Background

R-spondin3 (RSPO3), an activator of Wnt/β-catenin signaling, plays a key role in tumorigenesis of various cancers. RSPO3 contains two adjacent cysteine-rich furin-like domains (aa 35-135) with one potential N-glycosylation site (aa 36), followed by a thrombospondin (TSP-1) motif (aa 147-207) and a region rich in basic residues (aa 211-269). RSPO3 is a novel contraction-inducible myokine produced by cultured human myotubes. Human RSPO3 is a paracrine factor that may positively participate in the myogenesis processes of myoblasts and satellite cells. RSPO3 promotes the tumor growth of choriocarcinoma via Akt/PI3K/ERK signaling, which supports RSPO3 as an oncogenic driver promoting the progression of choriocarcinoma. RSPO3 plays a role in the regulation of Wnt (wingless-type MMTV integration site family)/beta-catenin and Wnt/planar cell polarity (PCP) signaling pathways, which are involved in development, cell growth and disease pathogenesis. Genome-wide association studies suggest a correlation of this protein with bone mineral density and risk of fracture.

Best dog toy on the market
Size: Medium (Pack of 1)
Our blue heeler doesn't go anywhere without this bone. He can chew on it till the cows come home and he doesn't get through it. Rebar enjoys it, plays with it for hours, it's a perfect size for both small and medium sized dogs, doesn't squeak and is easy to throw and retrieve.
