This study was performed to elucidate the effects of a high-fat/high-sucrose (HF/HS) diet on pancreatic islet functions in relation to modulation of WNT ligand expression in β-cells. Materials and Methods: Mice were fed either standard mouse chow or a HF/HS diet from 8 weeks of age. At 20 weeks of age, intraperitoneal glucose tolerance tests were performed in both groups of mice, followed by euthanasia and isolation of pancreatic islets. WNT-related gene expression in islets and MIN6 cells was measured by quantitative real-time RT-PCR. To explore the direct effects of WNT signals on pancreatic β-cells, MIN6 cells were exposed to recombinant mouse WNT4 protein (rmWNT4) for 48 h, and glucose-induced insulin secre- tion was measured. Furthermore, Wnt4 siRNAs were transfected into MIN6 cells, and cell viability and insulin secretion were measured in control and Wnt4 siRNA-transfected MIN6 cells. -

WNT10A Gene Wnt Family Member 10A
WNT10A gene Wnt family member 10A Normal Function The WNT10A gene is part of a large family of WNT genes, which play critical roles in development starting before birth. These genes provide instructions for making proteins that participate in chemical signaling pathways in the body. Wnt signaling controls the activity of certain genes and regulates the interactions between cells during embryonic development. The protein produced from the WNT10A gene plays a role in the development of many parts of the body. It appears to be essential for the formation of tissues that arise from an embryonic cell layer called the ectoderm. These tissues include the skin, hair, nails, teeth, and sweat glands. Researchers believe that the WNT10A protein is particularly important for the formation and shaping of both baby (primary) teeth and adult ( permanent) teeth. Health Conditions Related to Genetic Changes Hypohidrotic ectodermal dysplasia Several mutations in the WNT10A gene have been found to cause hypohidrotic ectodermal dysplasia, the most common form of ectodermal dysplasia. Starting before birth, ectodermal dysplasias result in the abnormal development of the skin, hair, nails, teeth, and sweat glands. Hypohidrotic ectodermal dysplasia is characterized by a reduced ability to sweat (hypohidrosis), sparse scalp and body hair (hypotrichosis), and several missing teeth (hypodontia) or teeth that are malformed. WNT10A gene mutations account for about 5 percent of all cases of hypohidrotic ectodermal dysplasia. Most of the WNT10A gene mutations associated with hypohidrotic ectodermal dysplasia change single protein building blocks (amino acids) in the WNT10A protein, which impairs its function. The resulting shortage of functional WNT10A protein disrupts Wnt signaling during the development of ectodermal tissues, particularly the teeth. -

Chemoresistance and the development of recurrent tumors are two of the leading factors of cancer-related deaths. The Adenomatous Polyposis Coli (APC) tumor suppressor is lost in many different cancers, including colorectal, breast, and prostate cancer, and its loss correlates with a decreased overall survival in cancer patients. While APC is commonly known for its role as a negative regulator of the WNT pathway, APC has numerous binding partners and functional roles. Through APC’s interactions with DNA repair proteins, DNA replication proteins, tubulin, and other components, recent evidence has shown that APC regulates the chemotherapy response in cancer cells. In this review article, we provide an overview of some of the cellular processes in which APC participates and how they impact chemoresistance through both epithelial- and TME-derived mechanisms. Keywords: adenomatous polyposis coli; chemoresistance; WNT signaling 1. -
The Sec14-Like Phosphatidylinositol Transfer Proteins Sec14l3/SEC14L2
RESEARCH ARTICLE The Sec14-like phosphatidylinositol transfer proteins Sec14l3/SEC14L2 act as GTPase proteins to mediate Wnt/Ca2+ signaling Bo Gong, Weimin Shen, Wanghua Xiao, Yaping Meng, Anming Meng*, Shunji Jia* State Key Laboratory of Membrane Biology, Tsinghua-Peking Center for Life Sciences, School of Life Sciences, Tsinghua University, Beijing, China Abstract The non-canonical Wnt/Ca2+ signaling pathway plays important roles in embryonic development, tissue formation and diseases. However, it is unclear how the Wnt ligand-stimulated, G protein-coupled receptor Frizzled activates phospholipases for calcium release. Here, we report that the zebrafish/human phosphatidylinositol transfer protein Sec14l3/SEC14L2 act as GTPase proteins to transduce Wnt signals from Frizzled to phospholipase C (PLC). Depletion of sec14l3 attenuates Wnt/Ca2+ responsive activity and causes convergent and extension (CE) defects in zebrafish embryos. Biochemical analyses in mammalian cells indicate that Sec14l3-GDP forms complex with Frizzled and Dishevelled; Wnt ligand binding of Frizzled induces translocation of Sec14l3 to the plasma membrane; and then Sec14l3-GTP binds to and activates phospholipase Cd4a (Plcd4a); subsequently, Plcd4a initiates phosphatidylinositol-4,5-bisphosphate (PIP2) signaling, ultimately stimulating calcium release. Furthermore, Plcd4a can act as a GTPase-activating protein to accelerate the hydrolysis of Sec14l3-bound GTP to GDP. Our data provide a new insight into GTPase protein-coupled Wnt/Ca2+ signaling transduction.
