Coexpression Analysis of the EZH2 Gene Using The Cancer Genome Atlas and Oncomine Databases Identifies Coexpressed Genes Involved in Biological Networks in Breast Cancer, Glioblastoma, and Prostate Cancer.

CONCLUSIONS Coexpression analysis of EZH2 identified its role in the cell cycle, mitosis, and DNA repair. The molecular mechanisms involved in EZH2 gene expression in the cell response to DNA damage requires further study to determine whether EZH2 is a potential human cancer biomarker.

AbstractAs standard treatments for cancer, DNA-damaging chemotherapeutic agents and irradiation therapy improve survival in patients with various cancers. Wee1, a kinase associated with the cell cycle, causes G2/M cell cycle arrest to allow repair of injured DNA in cancer cells, and a Wee1 inhibitor has been confirmed to lead to apoptosis in cancer cells. Recently, there has been renewed interest in exploring the immune environment which plays a significant role in tumour suppression. A Wee1 inhibitor combined with radiotherapy has been tested in lung, pancreatic, and prostate cancer and melanoma in vivo or in vitro. There...

ConclusionIn this study, we identified aBRCA2 c.8827C>T nonsense mutation with a truncated BRCA2 protein in a consanguineous Chinese Han family, suggesting individuals with this mutation should be regularly screened for malignancies such as breast, prostate, and ovarian cancer. Our study verified the function of thisBRCA2 mutation site and provided a new target for the precise treatment of such patients.

Abstract Sumoylation is the Posttranslational modification gaining most of the research interest recently. Sumoylation is involved in various crucial functions of the cell such as regulation of cell cycle, DNA damage repair, apoptosis etc. Oncology is advancing in radiotherapy, targeted chemotherapy, various forms of immunotherapy and targeted gene therapy. Researches are being conducted to prove its connotation with a variety of cancers and inhibitors are being developed to obstruct the fatal effect caused by misbalance of the SUMO-catalytic cycle. It has been shown that upregulation of certain enzymes of Sumoyla...

(Institute of Cancer Research) A drug already licensed for the treatment of breast and ovarian cancers is more effective than targeted hormone therapy at keeping cancer in check in some men with advanced prostate cancer, a major clinical trial reports.Olaparib, a pill lacking the side effects of chemotherapy, can target an Achilles heel in prostate cancers with a weakness in their ability to repair damaged DNA.

Immunotherapy has revolutionized the treatment of both hematological malignancies and solid tumors. The use of immunotherapy has improved outcome for patients with cancer across multiple tumor types, including lung, melanoma, ovarian, genitourinary, and more recently breast cancer with durable responses seen even in patients with widespread metastatic disease. Despite the promising results, immunotherapy still helps only a subset of patients due to overall low response rates. Moreover, the response to immunotherapy is highly cancer specific and results have not been as promising in cancers that are considered less immunoge...

SrivastavaAbstractThe recent development of high throughput compound screening has allowed drug repurposing to emerge as an effective avenue for discovering novel treatments for cancer. FDA-approved antipsychotic drugs fluspirilene, penfluridol, and pimozide are clinically used for the treatment of psychotic disorders, primarily schizophrenia. These compounds, belong to diphenylbutylpiperidine class of antipsychotic drugs, are the potent inhibitors of dopamine D2 receptor and calcium chan...

AbstractBackgroundPoly(ADP-ribose) polymerases (PARPs) play a key role in DNA damage repair (DDR). DDR defects due to HRRm (eg BRCA mutation [BRCAm]) or resulting in HRD (eg global loss of heterozygosity) may sensitize tumors to PARP inhibitors, eg olaparib. Olaparib monotherapy has activity in BRCAm ovarian, breast, pancreatic, and prostate cancer, and in prostate cancer with DDR defects beyond BRCAm (TOPARP). Olaparib improved efficacy outcomes vs placebo/chemotherapy as treatment in  ≤ 3rd-line (3L) HER2-negative BRCAm breast cancer (OlympiAD) and ≥2L BRCAm ovarian cancer (SOLO3), and maintenance the...

In conclusion, our data show how oncogenic and tumor-suppressive drivers of cellular senescence act to regulate surveillance processes that can be circumvented to enable SnCs to elude immune recognition but can be reversed by cell surface-targeted interventions to purge the SnCs that persist in vitro and in patients. Since eliminating SnCs can prevent tumor progression, delay the onset of degenerative diseases, and restore fitness; since NKG2D-Ls are not widely expressed in healthy human tissues and NKG2D-L shedding is an evasion mechanism also employed by tumor cells; and since increasing numbers of B cells express NKG2D ...
