In the United States each year, almost 13,000 deaths are attributable to bladder cancer, with the majority of these deaths related to higher stage, muscle-invasive solid tumors. Epigenetic silencing of the secreted frizzled receptor proteins (SFRP), antagonists of the WNT pathway, leads to constitutive WNT signaling, altering cell morphology and motility. Identifying alterations in this pathway...
We evaluated the healing potential of human fetal aorta-derived CD133(+) progenitor cells and their conditioned medium (CD133(+) CCM) in a new model of ischemic diabetic ulcer. Streptozotocin-induced diabetic mice underwent bilateral limb ischemia and wounding. One wound was covered with collagen containing 2x10(4) CD133(+) or CD133(-) cells or vehicle. The contralateral wound, covered with onl...
Secreted frizzled-related proteins (sFRPs) are secreted glycoproteins involved in neoplastic growth. Four hormones synthesized in the heart, namely vessel dilator, atrial natriuretic peptide (ANP), kaliuretic peptide (KP) and long-acting natriuretic peptide (LANP), have anticancer effects both in vitro and in vivo. These heart hormones were evaluated for their ability to inhibit sFRP-3, which i...
OBJECTIVE Overload-induced heart failure is associated with myocyte apoptosis induced by unknown mechanisms. Wnt genes encode secreted signaling molecules that bind to frizzled receptors and stabilize cytosolic beta-catenin which is translocated into the nucleus, acts as transcriptional activator and imparts an apoptosis resistant phenotype. This signaling pathway is antagonized by secreted fri...
Objective: To investigate the correlation between serum secretory frizzled-related protein 5 (SFRP-5) expression levels and insulin resistance glucolipid metabolism in patients with gestational diabetes mellitus (GDM). Methods: Baseline data were collected from 58 GDM 51 healthy controls who admitted Affiliated Hospital of Hebei University May 2020 to June 2022. sSTRA5 concentrations peripheral...
Polarization of node cells along the anterior-posterior axis of mouse embryos is responsible for left-right symmetry breaking. How node cells become polarized has remained unknown, however. Wnt5a and Wnt5b are expressed posteriorly relative to the node, whereas genes for Sfrp inhibitors of Wnt signaling are expressed anteriorly. Here we show that polarization of node cells is impaired in Wnt5a-...
BACKGROUND Conserved Wnt ligands are critical for signalling during development; however, various factors modulate their activity. Among these factors are the Secreted Frizzled-Related Proteins (SFRP). We previously isolated the SFRP-4 gene from an involuting rat mammary gland and later showed that transgenic mice inappropriately expressing SFRP-4 during lactation exhibited a high level of apop...
The Wnt (wingless-type) signaling pathway plays an important role in embryonic development, tissue homeostasis, and tumor progression becaluse of its effect on cell proliferation, migration, and differentiation. Secreted frizzled-related proteins (SFRPs) are extracellular inhibitors of Wnt signaling that act by binding directly to Wnt ligands or to Frizzled receptors. In recent years, aberrant ...
