Description
Intravaginal HIV microbicides could provide women with a self-controlled means for HIV prevention, but results from clinical trials have been largely disappointing. We postulated that unrecognized effects of intravaginal gels on the upper female reproductive tract (FRT) might contribute to the lower-than-expected efficacy of HIV microbicides. In this observational crossover study, 28 healthy female volunteers used no product (control cycle) or used a nightly application of intravaginal nonoxynol-9 gel [N9] as a 'failed' microbicide or the universal placebo gel [UPG] as a 'safe' gel, from the end of menses to the mid-luteal phase (intervention cycles). They then underwent sample collection for measurements of T-cell phenotypes, transcriptional profiling, and protein levels from 3 anatomic sites above the vagina: the cervical transformation zone, the endocervix and the endometrium. We used hierarchical statistical models to estimate mean (95% CI) intervention:control fold-changes in relevant phenotype levels. Exposure to N9 and UPG generated a common 'harm signature' that included transcriptional up-regulation of inflammatory genes CCL20 and IL8 in the cervix, decreased protein concentrations of secretory leukocyte protease inhibitor and increased percentages of terminally differentiated CD4+ effector T-cells in the endocervix, and transcriptional up-regulation of inflammatory mediators KIR3DS1, glycodelin-A, and osteopontin in the endometrium. These results underscore the need to consider the effects of microbicide agents and gel excipients on the upper FRT in studies of vaginal microbicides. Given the pro-inflammatory effects of UPG on the upper FRT, it may not be a suitable placebo for microbicide trials.

Description
Cutaneous, acral and mucosal subtypes of melanoma were evaluated by whole-genome sequencing, revealing genes affected by novel recurrent mutations to the promoter (TERT, DPH3, OXNAD1, RPL13A, RALY, RPL18A, AP2A1), 5-UTR (HNRNPUL1, CCDC77, PES1), and 3-UTR (DYNAP, CHIT1, FUT9, CCDC141, CDH9, PTPRT) regions. TERT promoter mutations had the highest frequency of any mutation, but neither they nor ATRX mutations, associated with the alternative telomere lengthening mechanism, were correlated with greater telomere length. Genomic landscapes largely reflected ultraviolet radiation mutagenesis in cutaneous melanoma and provided novel insights into melanoma pathogenesis. In contrast, acral and mucosal melanomas exhibited predominantly structural changes, and mutation signatures of unknown aetiology not previously identified in melanoma. The majority of melanomas had potentially actionable mutations, most of which were in components of the mitogen-activated protein kinase and phosphoinositol kinase pathways.

- Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Microarrays were used to examine gene expression changes that may be present in the fallopian tube epithelium of morphologically normal BRCA1 mutation positive and negative subjects. Fallopian tube epithelia has been implicated as an early point of origin for serous carcninoma. By examining the early events present in the microenvironment of this tissue between BRCA1 mutation carriers and non-carriers, we hoped to elucidate mechanisms that may lead to the development of epithelial ovarian cancer.
Publication Title
Identification of abrogated pathways in fallopian tube epithelium from BRCA1 mutation carriers.
