Cell signaling molecules in hydra: insights into evolutionarily ancient functions of signaling pathways

New Insights into Reelin-Mediated Signaling Pathways

Reelin, a multifunctional extracellular protein that is important for mammalian brain development and function, is secreted by different cell types in the prenatal or postnatal brain. The spatiotemporal regulation of Reelin expression and distribution during development relates to its multifaceted function in the brain. Prenatally Reelin controls neuronal radial migration and proper positioning...

Renal carcinogenesis--insights into signaling pathways.

Renal cancer represents about 3% of all human malignancies, 96% of cases being sporadic forms and only 4% hereditary. Research in renal tumor pathogenesis is currently oriented on the genetic and proteins framework of the renal cell carcinoma, with the aim to translate the level of knowledge on tumor subtypes from histological to molecular issues, simultaneously with the deciphering of the mann...

TLR2 and TLR4 Signaling Pathways and Gastric Cancer: Insights from Transcriptomics and Sample Validation

Background: Pattern recognition receptors, especially toll-like receptors (TLRs), as the first line of defense for pathogen detection, were found to be associated with H.­ pylori infection and gastric cancer (GC). However, the expression levels of TLRs, i.e. TLR2 and TLR4, as the main receptors sensed by H.­ pylori, still remain largely ambiguous. We aimed to investigate the patterns of key tra...

Mesenchymal Stem Cells: Signaling Pathways in Transdifferentiation Into Retinal Progenitor Cells

Several signaling pathways and transcription factors control the cell fate in its in vitro development and differentiation. The orchestrated use of these factors results in cell specification. In coculture methods, many of these factors secrete from host cells but control the process. Today, transcription factors required for retinal progenitor cells are well known, but the generation of these ...
