EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Course Timetabling using Genetic Algorithm and Fuzzy Cross-Over

open access: yesJOIV : International Journal on Informatics Visualization
Course timetabling at universities presents a complex problem due to the limited timeframe to create schedules that avoid conflicts between activities. This issue becomes more challenging as the number of activities increases while the available rooms remain constant. Numerous studies have attempted to automate the scheduling process, but their success

My Favorite Sites: Linkage of genetics and ethics: more crossing over is needed [PDF]

open access: yesBiology of the Cell, 2005
Since the development of recombinant DNA technology in the mid 1970s, there has been increasing interest in the ethical, legal, and social implications of genetics and related fields. The web sites of five different organizations (government, academic, and independent not‐for‐profit) that deal explicitly with genetics and ethics are reviewed here. Some

Genetic Variation in a Crossing Population of Camellia oleifera Based on ddRAD Sequencing and Analysis of Association with Fruit Traits

open access: yesCurrent Issues in Molecular Biology
Tea oil is an important high-quality edible oil derived from woody plants. Camellia oleifera is the largest and most widely planted oil-producing plant in the Camellia genus in China, and its seeds are the most important source for obtaining tea oil.

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Interrogating the immune landscape of microsatellite stable RAS‐mutated colon cancer

open access: yesMolecular Oncology, EarlyView.
COLOSSUS project RAS‐mutated MSS colon cancer study explored transcriptomics and immune cell density by immunohistochemistry (IHC), Immunoscore (IS), ISIC/TuLIS scores, mutation counts, and detected different prevalences but similar microenvironment composition across immune markers with clinical relevance for future immunotherapy combination ...

SEGREGATION DISTORTION AND CROSSING OVER IN MALES OF DROSOPHILA ANANASSAE. I: PRELIMINARY GENETIC ANALYSIS

open access: yesGenetics, 1971
ANDLER and NOVITSKI (1957) proposed the term “meiotic drive” (or segregation distortion) to describe a condition which leads to unequal segregation of the two alleles present in a heterozygote in consequence of certain aberrant mechanisms during meiosis.

Overexpression of NtGSTU10 gene enhances nicotine content in hybrids by promoting the synthesis and transport metabolism of nicotine

open access: yesBMC Biotechnology
Background Nicotine exhibits positive heterosis, and through its utilization, new tobacco varieties with ideal nicotine content have been bred. However, the potential mechanism underlying the increased transport and nicotine accumulation capacity in ...

An efficient method for markerless mutant generation by allelic exchange in Clostridium acetobutylicum and Clostridium saccharobutylicum using suicide vectors

open access: yesBiotechnology for Biofuels, 2019
Background Clostridium acetobutylicum and Clostridium saccharobutylicum are Gram-positive, spore-forming, anaerobic bacterium capable of converting various sugars and polysaccharides into solvents (acetone, butanol, and ethanol).

Somatic mutational landscape in von Hippel–Lindau familial hemangioblastoma

open access: yesMolecular Oncology, EarlyView.
The causes of central nervous system (CNS) hemangioblastoma in Von Hippel–Lindau (vHL) disease are unclear. We used Whole Exome Sequencing (WES) on familial hemangioblastoma to investigate events that underlie tumor development. Our findings suggest that VHL loss creates a permissive environment for tumor formation, while additional alterations ...
