Promoter Orientation of Prokaryotic Phase-variable Genes by PCR
Bio-Protocol, 2012 One major mechanism of phase variable gene expression in prokaryotes is through inversion of the promoter element for a gene or operon. This protocol describes how to detect the promoter orientation of a phase-variable gene by PCR.

International Journal of Agricultural Sustainability, 2021 Sustainable intensification (SI) is promoted as a rural development paradigm for sub-Saharan Africa. Achieving SI requires smallholder farmers to have access to information that is context-specific, increases their decision-making capacities, and adapts ...

Seed treatments for improved germination of caper (Capparis spinosa) [PDF]
, 2004 [EN] This study analyses the effects of seven treatments for removing hardseededness and four for breaking physiological dormancy in caper seeds. Seeds were germinated in a growth chamber and the maximum germination percentage, the time to reach 50% of ...

COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells
Molecular Oncology, EarlyView.This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

SEMIPERMEABILITY OF SEED COVERINGS AND STIMULATION OF SEEDS [PDF]
Plant Physiology, 1927 In a previous paper (6) the writer assumed that the methods of seed stimulation, advocated by Popoff (9) are of little value for agriculture and horticulture [cf. also Bredeman (1)]. Many publications witness the great interest on the subject of seed stimulation.

Molecular 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

Molecular 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 ...
