Cell Cycle-Dependent Expression of Bk Channels in Human Mesenchymal Endometrial Stem Cells.

The study of ion channels in stem cells provides important information about their role in stem cell fate. Previously we have identified the activity of calcium-activated potassium channels of big conductance (BK channels) in human endometrium-derived mesenchymal stem cells (eMSCs). BK channels could have significant impact into signaling processes by modulating membrane potential.

Cytogenetic and Transcriptomic Analysis of Human Endometrial MSC Retaining Proliferative Activity after Sublethal Heat Shock.

Temperature is an important exogenous factor capable of leading to irreversible processes in the vital activity of cells. However, the long-term effects of heat shock (HS) on mesenchymal stromal cells (MSC) remain unstudied. We investigated the karyotype and DNA repair drivers and pathways in the human endometrium MSC (eMSC) survived progeny at passage 6 after sublethal heat stress (sublethal heat stress survived progeny (SHS-SP)).

Somatic polyploidy is associated with the upregulation of c-MYC interacting genes and EMT-like signature.

The dependence of cancer on overexpressed c-MYC and its predisposition for polyploidy represents a double puzzle. We address this conundrum by cross-species transcription analysis of c-MYC interacting genes in polyploid vs. diploid tissues and cells, including human vs.

Insulin receptor-related receptor as an extracellular alkali sensor.

The insulin receptor-related receptor (IRR), an orphan receptor tyrosine kinase of the insulin receptor family, can be activated by alkaline media both in vitro and in vivo at pH >7.9. The alkali-sensing property of IRR is conserved in frog, mouse, and human.
