The status of p53 in a tumor can be inferred by next-generation sequencing (NGS) or immunohistochemistry (IHC). We examined the association between IHC and sequence whether alone, integrated with TP53 NGS, predicts outcome.From GOG-86P, randomized phase II study chemotherapy combined either bevacizumab temsirolimus advanced endometrial cancer, 213 cases had protein expression data measured NGS data. An analysis was designed to integrate presence absence mutation. These variables were further...

Breast cancer cell lines are frequently used as model systems to study the cellular properties and biology of breast cancer. Our objective was characterize a large, commonly employed panel obtained from American Type Culture Collection (ATCC 30-4500 K) enable researchers make more informed decisions in selecting for specific studies. Information about these wide variety sources. In addition, new information pathways that activated within each line generated. We determined key protein...

Tumor suppressor p53 is responsible for enforcing cell cycle checkpoints at G1/S and G2/M in response to DNA damage, thereby allowing both normal tumor cells repair before entering S M. However, with absent or mutated are able activate alternative signaling pathways that maintain the checkpoint, which becomes uniquely critical survival of such cells. We hypothesized abrogation G2 checkpoint might preferentially sensitize p53-defective DNA-damaging agents spare intact function. The tyrosine...

In previous studies, neoadjuvant chemotherapy followed by interval debulking surgery was not inferior to primary cytoreductive as initial treatment for advanced epithelial ovarian cancer. Our study aimed compare surgical and survival outcomes between the two treatments in a large national database.Data were extracted from National Cancer Database January 2004 December 2015. Patients with FIGO (International Federation of Gynecologists Obstetricians) stage III-IV cancer known sequence...

Venous thromboembolisms (VTEs) have been a leading secondary cause of death among ovarian cancer patients, prompting multiple studies risk factors. The objective this meta-analysis is to quantify the associations between VTE and most commonly reported factors patients. PubMed, Embase, Cumulative Index Nursing Allied Health Literature (CINAHL) were used identify observational studies. Two reviewers independently abstracted data assessed quality via Newcastle–Ottawa tool. A random effects...

Translation termination is promoted by class 1 and 2 release factors in all domains of life. While the role bacterial factors, RF1 RF2, translation well understood, precise contribution factor, RF3, to this process remains less clear. Here, we use a combination binding assays pre-steady state kinetics provide kinetic thermodynamic framework for understanding translational GTPase RF3 termination. First, find that GDP GTP have similar affinities that, on average, t 1/2 nucleotide dissociation...

In bacteria, stop codons are recognized by two similar class 1 release factors, factor (RF1) and 2 (RF2). Normally, during termination, the 3 (RF3), a GTPase, functions downstream of peptide where it accelerates dissociation RF1/RF2 prior to ribosome recycling. addition their canonical function in both classes also involved post peptidyl transfer quality control (post PT QC) mechanism termination factors recognize mismatched (i.e. error-containing) complexes promote premature termination....

Abstract Nearly a third of patients with high-grade serous ovarian cancer (HGSC) do not respond to initial therapy and have an overall poor prognosis. However, there are no validated tools that accurately predict which will respond. Our objective is create validate accurate models prediction for treatment response in HGSC. This retrospective case–control study integrates comprehensive clinical genomic data from 88 HGSC single institution. Responders were those progression-free survival at...

Few advances in the treatment of advanced epithelial ovarian cancer have improved patient overall survival. However, incorporation intraperitoneal administration platinum based chemotherapy to standard was one such advancement. It is understood that regimen associated with increased toxicity when compared intravenous alone; however, information regarding specific risk ototoxicity lacking literature.
