A C-type lectin from Bothrops jararacussu venom can adhere to extracellular matrix proteins and induce the rolling of leukocytes

Journal of Venomous Animals and Toxins including Tropical Diseases, 2007
Purification of a lectin from Bothrops jararacussu venom (BjcuL) was carried out using agarose-D-galactose affinity gel. MALDI-TOF gave a major signal at m/z 32028, suggesting the presence of a dimmer composed of two identical subunits.

Inside Out Integrin Activation Mediated by PIEZO1 Signaling in Erythroblasts

Frontiers in Physiology, 2020
The non-selective mechanosensitive ion channel PIEZO1 controls erythrocyte volume homeostasis. Different missense gain-of-function mutations in PIEZO1 gene have been identified that cause Hereditary Xerocytosis (HX), a rare autosomal dominant haemolytic ...

Expression of variant fibronectins in wound healing: cellular source and biological activity of the EIIIA segment in rat hepatic fibrogenesis

Journal of Cell Biology, 1994
We have examined the cell-specific expression of two fibronectin isoforms, EIIIA and EIIIB, during experimental hepatic fibrosis induced by ligation of the biliary duct.

Phytophthora have distinct endogenous small RNA populations that include short interfering and microRNAs. [PDF]

PLoS ONE, 2013
In eukaryotes, RNA silencing pathways utilize 20-30-nucleotide small RNAs to regulate gene expression, specify and maintain chromatin structure, and repress viruses and mobile genetic elements.

Fibroblast cellular and plasma fibronectins are similar but not identical

Journal of Cell Biology, 1979
Fibronectins are multimeric, adhesive glycoproteins present on cell surfaces and circulating in blood. Cellular fibronectin produced by fibroblasts in vitro and fibronectin isolated from plasma are known to be very similar immunologically and ...

Pathophysiology of matrix metalloproteinases in breast cancer progression

Journal of Clinical and Scientific Research, 2019
Matrix metalloproteinases (MMPs) are secretary or membrane type proteolytic enzymes that act on extracellular matrix protein components such as collagens, gelatins, elastins, laminins, fibronectins, and integrins. MMPs are synthesized as zymogens and are

Microenvironment commits breast tumor ECs to dedifferentiation by micro-RNA-200-b-3p regulation and extracellular matrix remodeling

Frontiers in Cell and Developmental Biology, 2023
Introduction: Hypoxia shapes the tumor microenvironment, modulates distinct cell population activities, and activates pathological angiogenesis in cancer, where endothelial cells (ECs) are the most important players.
