    • C-terminally truncated human O6-alkylguanine-DNA alkyltransferase retains activity.

      Elder, Rhoderick H; Tumelty, J; Douglas, K T; Margison, Geoffrey P; Rafferty, Joseph A; CRC Department of Carcinogenesis, Paterson Institute for Cancer Research, Christie Hospital (NHS) Trust, Manchester, U.K. (1992-08-01)
      A cDNA encoding the human O6-alkylguanine-DNA alkyltransferase (ATase; EC 2.1.1.63; methylated-DNA: protein-cysteine methyltransferase) has been manipulated to generate a C-terminally deleted protein which retains full methyl-transfer activity. The elimination of 22 amino-acid residues from the C-terminus was achieved by endonuclease-SacI digestion of the 623 bp cDNA coding sequence and ligation of a SacI/HindIII linker containing an in-frame stop codon. The truncated protein was characterized by its reduced molecular mass in immunoblots probed with an antiserum against the full-length protein and by fluorography after incubation with [3H]methylated calf thymus DNA. The rate of methyl transfer was virtually identical for the full-length and truncated ATases. The construction of such a truncated, yet still functional, ATase, with a molecular mass of 19.7 kDa should facilitate a detailed n.m.r. structural study and help to determine the functional significance of the C-terminal domain of mammalian ATases.
    • The C/EBPdelta protein is stabilized by estrogen receptor α activity, inhibits SNAI2 expression and associates with good prognosis in breast cancer.

      Hypoxia and inflammatory cytokines like interleukin-6 (IL-6, IL6) are strongly linked to cancer progression, and signal in part through the transcription factor Ccaat/enhancer-binding protein δ (C/EBPδ, CEBPD), which has been shown to promote mesenchymal features and malignant progression of glioblastoma. Here we report a different role for C/EBPδ in breast cancer. We found that the C/EBPδ protein is expressed in normal breast epithelial cells and in low-grade cancers. C/EBPδ protein (but not mRNA) expression correlates with estrogen receptor (ER+) and progesterone receptor (PGR) expression and longer progression-free survival of breast cancer patients. Specifically in ER+ breast cancers, CEBPD-but not the related CEBPB-mRNA in combination with IL6 correlated with lower risk of progression. Functional studies in cell lines showed that ERα promotes C/EBPδ expression at the level of protein stability by inhibition of the FBXW7 pathway. Furthermore, we found that C/EBPδ attenuates cell growth, motility and invasiveness by inhibiting expression of the SNAI2 (Slug) transcriptional repressor, which leads to expression of the cyclin-dependent kinase inhibitor CDKN1A (p21(CIP1/WAF1)). These findings identify a molecular mechanism by which ERα signaling reduces the aggressiveness of cancer cells, and demonstrate that C/EBPδ can have different functions in different types of cancer. Furthermore, our results support a potentially beneficial role for the IL-6 pathway specifically in ER+ breast cancer and call for further evaluation of the role of intra-tumoral IL-6 expression and of which cancers might benefit from current attempts to target the IL-6 pathway as a therapeutic strategy.Oncogene advance online publication, 16 May 2016; doi:10.1038/onc.2016.156.
    • C1q binding activity in the sera of patients with chronic lung diseases.

      Cooper, K Michael; Moore, Michael; Hilton, A M; Paterson Laboratories, Christie Hospital and Holt Radium Institute, Manchester, UK (1981-07)
      Sera from patients with chronic lung diseases were tested for the presence of immune complexes (ICs) by the 125I-C1q-binding assay. Contrary to earlier reports, modification of the test system by addition of heparin decreased rather than increased the ability of the test to discriminate between control and pathological sera. Using the unmodified system, elevated C1q-binding activity (C1qBA) was found in patients with asthma (18%), chronic bronchitis (18%), sarcoidosis (18%), fibrosing alveolitis (50%), bronchogenic carcinoma (52%) and bronchiectasis (67%). Studies with the reducing agent 2-mercaptoethanol (2-ME) suggested a role for IgM rheumatoid factor (RF) and/or IgG-containing complexes in the C1q-reactive material of sera from patients with bronchiectasis and bronchogenic carcinoma. In the latter two groups, C1qBA was found to correlate with serum levels of IgG and IgA but not with C3 and C4. A weak condition between levels of C-reactive protein (CRP) and C1qBA was found in the bronchogenic carcinoma group. Carcinoembryonic antigen (CEA) levels were elevated in all groups studied but no correlation with C1qBA was demonstrated, suggesting that CEA and CEA-ICs, if present, do not have an influence on the C1qBA of such sera. The results indicate that elevated serum C1qBA is a concomitant of both chronic inflammatory and neoplastic diseases of the lung but the extent of any similarity in the non-immunoglobulin components of the immune complexes in the respective conditions remains unknown.
    • CADRE: the Central Aspergillus Data REpository.

      Mabey, J E; Anderson, M J; Giles, P F; Miller, Crispin J; Attwood, Teresa K; Paton, N W; Bornberg-Bauer, E; Robson, G D; Oliver, S; Denning, David W; et al. (2004-01-01)
      CADRE is a public resource for housing and analysing genomic data extracted from species of Aspergillus. It arose to enable maintenance of the complete annotated genomic sequence of Aspergillus fumigatus and to provide tools for searching, analysing and visualizing features of fungal genomes. By implementing CADRE using Ensembl, a framework is in place for storing and comparing several genomes: the resource will thus expand by including other Aspergillus genomes (such as Aspergillus nidulans) as they become available. CADRE is accessible at http://www.cadre. man.ac.uk.

    • Calibration of low activity caesium tubes and needles traceable to the therapy level standard.

      Deshpande, N A; Wilkinson, John M; North Western Medical Physics Department, Christie Hospital, Manchester, UK. (1994-02)
      A technique for deriving the reference air kerma rate for low activity brachytherapy sources that is traceable to the therapy level standard at the National Physical Laboratory is presented. Correction factors have been generated to account for the finite source and detector size. The air kerma rate calibration of the secondary standard for caesium quality has been derived by polynomial curve fitting. The reference air kerma rates for several caesium tubes and needles have been determined and the results compared with the manufacturers' source test reports. For all the source types used the agreement between methods was within 2%.

    • Can metabolomics in addition to genomics add to prognostic and predictive information in breast cancer?

      Howell, Anthony; School of Cancer and Enabling Studies, University of Manchester, Paterson Institute for Cancer Research, Manchester, UK. anthony.howell@christie.nhs.uk (2010)
      Genomic data from breast cancers provide additional prognostic and predictive information that is beginning to be used for patient management. The question arises whether additional information derived from other 'omic' approaches such as metabolomics can provide additional information. In an article published this month in BMC Cancer, Borgan et al. add metabolomic information to genomic measures in breast tumours and demonstrate, for the first time, that it may be possible to further define subgroups of patients which could be of value clinically.

      Evidence for an association between aspirin or other nonsteroidal antiinflammatory drug (NSAID) use and basal cell carcinoma (BCC) has been inconsistent.
    • Can the uptake of breast screening by Asian women be increased? A randomized controlled trial of a linkworker intervention.

      Hoare, Tanya; Thomas, C; Biggs, A; Booth, M; Bradley, S; Friedman, E; Centre for Cancer Epidemiology, Christie Hospital NHS Trust, Withington, Manchester. (1994-06)
      This study investigates the effectiveness of a linkworker intervention, giving encouragement and explanations about breast screening, on the subsequent attendance for screening by 'Asian' women. The control group received no visits. The study population comprised all women with Asian names, from a batch of general practices where high proportions of patients were Asian, who were invited for screening. It was found that 59 per cent of the intervention group could be contacted by linkworkers. No difference in attendance was found between the intervention and control groups (49 per cent and 47 per cent). Twenty-five per cent of women were permanently or temporarily not resident at the invitation address. Attendance for screening was related to length of stay in the United Kingdom. This type of intervention was not a successful strategy for promoting uptake by Asian women, and indicates that it is essential to evaluate rigorously projects with such objectives.

    • A cancer cell-specific inducer of apoptosis.

      Human papillomavirus (HPV) DNA is found in virtually all cervical cancers, strongly suggesting that these viruses are necessary to initiate this disease. The HPV E2 protein is required for viral replication, but E2 expression is usually lost in HPV-transformed cells because of the integration of viral DNA into the host chromosome. Several studies have shown that the reintroduction of E2 into HPV-transformed cells can induce growth arrest and apoptotic cell death. This raises the possibility that E2 could be useful in the treatment of HPV-induced disease. However, the effects of E2 on cell proliferation are not limited to HPV-transformed cells. The E2 protein from HPV type 16 can induce apoptosis via at least two pathways. One pathway involves the binding of E2 to p53 and operates in HPV-transformed cells, many non-HPV-transformed cell lines, and untransformed normal cells. The second pathway requires the binding of E2 to the viral genome and operates only in HPV-transformed cells. A mutation in E2 that significantly reduces the binding of this protein to p53 abrogates the induction of apoptosis in non-HPV-transformed cells and normal cells, but has no effect on the ability of the mutated protein to induce apoptosis in HPV-transformed cells. Here we show that a chimeric protein consisting of this mutant of E2, fused to the herpes simplex virus type 1 VP22 protein, can traffic between cells in a three-dimensional tumor model and induce apoptosis in HPV-transformed cells with high specificity. This cancer cell-specific inducer of apoptosis may be useful in the treatment of cervical cancer and other HPV-induced diseases.

    • Cancer experience in the relatives of an unselected series of breast cancer patients.

      Teare, M Dawn; Wallace, S A; Harris, Martin; Howell, Anthony; Birch, Jillian M; Cancer Research Campaign Paediatric and Familial Cancer Research Group, Christie Hospital NHS Trust, Manchester, UK. (1994-07)
      First- and second-degree relatives of an unselected series of 402 breast cancer patients have been studied for their cancer experience. In the first-degree relatives an excess of all cancers is seen [overall relative risk (RR) = 1.28, P = 0.002; males RR = 1.26, P = 0.047; females RR = 1.30, P = 0.022). There is a marked excess of sarcoma (RR = 4.26, P = 0.0064); females are at high risk of breast cancer (RR = 2.68, P < 0.0001) and males have an excess of carcinoma of the lip, oral cavity and pharynx (RR = 4.22, P = 0.0032). Second-degree relatives have a non-significant excess of all cancers (RR = 1.14, P = 0.14); females have a borderline excess of breast cancer (RR = 1.53, P = 0.08) and an excess of carcinoma of the kidney (RR = 7.46, P = 0.0012) and males have an excess of carcinoma of the trachea and lung (RR = 1.50, P = 0.032). No excess of prostate or ovarian carcinoma was seen. Relatives are at slightly higher risk if the index patient is diagnosed between the ages of 40 and 49 (first-degree RR = 1.64, P = 0.007; second-degree RR = 1.43, P = 0.02). The excess of cancers, including breast cancers, is not limited to a few high-risk families, but appears to be spread across many. These observations may be accounted for by shared environmental factors within families or a common predisposing gene with low penetrance.
    • Cancer metabolism: a therapeutic perspective.

      Awareness that the metabolic phenotype of cells within tumours is heterogeneous - and distinct from that of their normal counterparts - is growing. In general, tumour cells metabolize glucose, lactate, pyruvate, hydroxybutyrate, acetate, glutamine, and fatty acids at much higher rates than their nontumour equivalents; however, the metabolic ecology of tumours is complex because they contain multiple metabolic compartments, which are linked by the transfer of these catabolites. This metabolic variability and flexibility enables tumour cells to generate ATP as an energy source, while maintaining the reduction-oxidation (redox) balance and committing resources to biosynthesis - processes that are essential for cell survival, growth, and proliferation. Importantly, experimental evidence indicates that metabolic coupling between cell populations with different, complementary metabolic profiles can induce cancer progression. Thus, targeting the metabolic differences between tumour and normal cells holds promise as a novel anticancer strategy. In this Review, we discuss how cancer cells reprogramme their metabolism and that of other cells within the tumour microenvironment in order to survive and propagate, thus driving disease progression; in particular, we highlight potential metabolic vulnerabilities that might be targeted therapeutically.

      Dive, Caroline; Shishido, S; Kuhn, P (2017-02-09)
      The Kuhn laboratory at the University of Southern California and the Dive laboratory at the Cancer Research UK's Manchester Institute are teaming up to apply new cancer cell detection technology to identify patients that will progress after initial treatment. Researchers will take a simple blood sample to identify early those patients whose cancer has returned, while analyzing CTCs in great detail, providing new clues on the most effective therapy for the patient's cancer.

    • Cancer phenotype correlates with constitutional TP53 genotype in families with the Li-Fraumeni syndrome.

      Birch, Jillian M; Blair, Val; Kelsey, Anna M; Evans, D Gareth R; Harris, Martin; Tricker, K J; Varley, Jennifer; CRC Paediatric and Familial Cancer Research Group and Department of Histopathology, Royal Manchester Children's Hospital, UK. (1998-09-03)
      The Li-Fraumeni cancer predisposition syndrome is associated with germline TP53 mutations in the majority of families. We have investigated cancer incidence in 34 Li-Fraumeni families, according to their constitutional TP53 mutation status. Families with germline missense mutations in the core DNA binding domain showed a more highly penetrant cancer phenotype than families with other TP53 mutations or no mutation. Cancer phenotype in families carrying such mutations was characterized by a higher cancer incidence and earlier ages at diagnosis, especially of breast cancer and brain tumours, compared with families carrying protein truncating or other inactivating mutations (P=0.03 for all cancers, P=0.006 for breast cancers, P=0.05 for brain tumours). Proband cancers showed significantly younger ages at diagnosis in those with missense mutations in the DNA binding domain than in those with protein inactivating mutations (P=0.031). In individuals with the former type of mutation, there was a significantly lower proportion of tumours which showed loss of the wild-type TP53 allele (P=0.004). These results are consistent with observations in experimental systems which demonstrate that certain mutations exhibit gain of function and/or dominant-negative properties. Our results support an enhanced oncogenic potential for such mutations in human populations.
    • Cancer stem cell metabolism.

      Cancer is now viewed as a stem cell disease. There is still no consensus on the metabolic characteristics of cancer stem cells, with several studies indicating that they are mainly glycolytic and others pointing instead to mitochondrial metabolism as their principal source of energy. Cancer stem cells also seem to adapt their metabolism to microenvironmental changes by conveniently shifting energy production from one pathway to another, or by acquiring intermediate metabolic phenotypes. Determining the role of cancer stem cell metabolism in carcinogenesis has become a major focus in cancer research, and substantial efforts are conducted towards discovering clinical targets.
