The goal of this study is to examine the effect of Prom1 -/- in mouse primary hepatocyte transcriptomes.Prominin-1 (Prom1) is a major cell surface marker of cancer stem cells, but its physiological functions in the liver have not been elucidated. We analyzed the lev...

Publication date: Available online 20 January 2020Source: Pathology - Research and PracticeAuthor(s): Maryam Moghadasi, Mohammadreza Alivand, Masoumeh Fardi, Kobra Shojaei Moghadam, Saeed SolaliAbstractMicroRNAs are characterized as small, single-stranded, non-coding RNA molecules that bind to their target mRNA to prevent protein synthesis. MicroRNAs regulate various normal processes; however, they are aberrantly regulated in many cancers. They control the expression of various genes, including cancer-related genes. This causes microRNAs to be considered as a good target for further investigations for designing novel thera...

This study aimed to analyze the role and content of sEVs released during the differentiation of colorectal cancer stem cells. Here we show that sEVs secretion during colon cancer stem cells differentiation is partially controlled by CD147, a well-known player involved in colon cancer tumorigenesis. CD147 + sEVs activate a signaling cascade in recipient cells inducing molecular invasive features in colon cancer cells. CD147 knockdown as well as anti-CD147 antibodies impaired sEVs release and downstream effects on recipient cells and blocking multivesicular body maturation prevented sEVs release during the differentiation. O...

The J.P. Morgan Healthcare conference runs every year in San Francisco, a big draw for the biotech industry, and many organizations take the opportunity to host events at the same time. Among these, the SENS Research Foundation has for the past few years hosted a pitch day in which biotech companies in the longevity industry, largely startups, present to that portion of the Bay Area investor community interested in funding the treatment of aging as a medical condition. I was there to present on progress at Repair Biotechnologies, and took some notes on the other companies as they talked about their work. Kimera Labs ...

d M. Al-Abd Thymoquinone (TQ) has shown substantial evidence for its anticancer effects. Using human breast cancer cells, we evaluated the chemomodulatory effect of TQ on paclitaxel (PTX). TQ showed weak cytotoxic properties against MCF-7 and T47D breast cancer cells with IC50 values of 64.93 ± 14 µM and 165 ± 2 µM, respectively. Combining TQ with PTX showed apparent antagonism, increasing the IC50 values of PTX from 0.2 ± 0.07 µM to 0.7 ± 0.01 µM and from 0.1 ± 0.01 µM to 0.15 ± 0.02 µM in MCF-...

ero The MYB binding protein 1A (MYBBP1A, also known as p160) acts as a co-repressor of multiple transcription factors involved in many physiological processes. Therefore, MYBBP1A acts as a tumor suppressor in multiple aspects related to cell physiology, most of them very relevant for tumorigenesis. We explored the different roles of MYBBP1A in different aspects of cancer, such as mitosis, cellular senescence, epigenetic regulation, cell cycle, metabolism plasticity and stemness. We especially reviewed the relationships between MYBBP1A, the inhibitory role it plays by binding and inactivating c-MYB and its regulation of...

Conclusions: Overall, we propose that the four hub genes may be potential targets in trastuzumab-resistant gastric cancer and that ISGs may play a key role in promoting trastuzumab resistance in GC. PMID: 31949544 [PubMed - in process]

This study provides strong evidence that following a healthy lifestyle can substantially extend the years a person lives disease-free." Commentary on Recent Evidence for Cognitive Decline to Precede Amyloid Aggregation in Alzheimer's Disease I can't say that I think the data presented in the research noted here merits quite the degree of the attention that it has been given in the popular science press. It is interesting, but not compelling if its role...

Contributors : Annika Fendler ; Kun Son ; Wei Chen ; Walter BirchmeierSeries Type : Expression profiling by high throughput sequencingOrganism : Homo sapiensWe detected and characterized CXCR4+MET+CD44+ cancer stem cells (CSCs) that were quantitatively correlated with aggressive tumors. Transcriptional profiling and single-cell sequencing revealed a strong activation of WNT and NOTCH signaling in these CSCs. CEL-Seq was performed to study heterogeneity of the CXCR4+MET+CD44+ population.
