Inhibition of heat shock protein 90 (Hsp90) abrogates signaling of multiple aberrantly activated oncogenic proteins simultaneously, particularly mutated or amplified kinases, which provides an attractive approach for cancer treatment. Here, we described that FS-93, a potent Hsp90 inhibitor, impacted the survival of several types of oncogene addicted cancer cells through inducing G2/M arrest and...

An i-motif is a non-canonical DNA structure implicated in gene regulation and linked to cancers. The C-rich strand of the HRAS oncogene, 5′-CGCCCGTGCCCTGCGCCCGCAACCCGA-3′ (herein referred as iHRAS), forms an vitro but its exact was unknown. member RAS proto-oncogene family. About 19 % US cancer patients carry mutations genes. We solved iHRAS at 1.77 Å resolution. reveals that folds into double ...

Background: Chemokines, proteins that operate within the body's immune system, play numerous roles in menstruation, bacterial infection, implantation of embryos, and the maintenance of early pregnancy. They are also strongly related to the pathogenesis of endometriosis. Materials and Methods: This is review article that were indentifical by computer search of MEDLINE (1984- 2013). Results:...

Cervical cancer is associated with persistent infections by high-risk Human Papillomavirus (HPV) types that may have nucleotide polymorphisms and, consequently, different oncogenic potentials. Therefore, this study aimed to evaluate the genetic variability and structural effects of E7 oncogene HPV58 in cervical scraping samples from Brazilian women. The was developed patients hospitals metropol...

Abstract Background Renal cell carcinoma (RCC) is one of the most common malignant tumors originating from renal parenchymal urinary epithelial system. Tripartite motif 47 (TRIM47) a member TRIM family proteins, which has E3 ligase activity and been demonstrated to be involved in occurrence prognosis many tumors. The main purpose this study explore role potential mechanism TRIM47 promoting biol...

Abstract Background The Chromobox (CBX) domain protein family, a core component of polycomb repressive complexes 1, is involved in transcriptional repression, cell differentiation, and program development by binding to methylated histone tails. Each CBX family member plays distinct role various biological processes through their own specific chromatin domains, due differences conserved sequence...

The genome of avian leukemia virus E26 shares homology with v-myb, the oncogene of avian myeloblastosis virus, and encodes a protein with an Mr of 135,000. Analyses of tryptic oligopeptides show that this protein is related to the proteins encoded by gag (Pr76gag) as well as v-myb (p45v-myb[AMV] ) and c-myb (p75c-myb). We found no evidence for the existence of additional myb-related proteins or...

Direct targeting of oncogenic MYC proteins has been an elusive goal of many cancer drug development efforts. In this issue of Cancer Discovery, Stegmaier and colleagues demonstrate that pharmacologically interfering with the bromodomain and extraterminal (BET) class of proteins potently depletes MYCN in neuroblastoma cells, resulting in cellular cytotoxicity and thus providing a novel approach ...

Although evidence obtained with the PC12 cell line has suggested a role for the ras oncogene proteins in the signal transduction of nerve growth factor-mediated fiber outgrowth, little is known about the signal transduction mechanisms involved in the neuronal response to neurotrophic factors in nontransformed cells. We report here that the oncogene protein T24-ras, when introduced into the cyto...
