Wnt proteins are secreted morphogens that are required for basic developmental processes, such as cell-fate specification, progenitor-cell proliferation and the control of asymmetric cell division, in many different species and organs. There are at least three different Wnt pathways: the canonical pathway, the planar cell polarity (PCP) pathway and the Wnt/Ca2+ pathway. In the canonical Wnt pathway, the major effect of Wnt ligand binding to its receptor is the stabilization of cytoplasmic beta-catenin through inhibition of the bea-catenin degradation complex. Beta-catenin is then free to enter the nucleus and activate Wnt-regulated genes through its interaction with TCF (T-cell factor) family transcription factors and concomitant recruitment of coactivators. Planar cell polarity (PCP) signaling leads to the activation of the small GTPases RHOA (RAS homologue gene-family member A) and RAC1, which activate the stress kinase JNK (Jun N-terminal kinase) and ROCK (RHO-associated coiled-coil-containing protein kinase 1) and leads to remodelling of the cytoskeleton and changes in cell adhesion and motility. WNT-Ca2+ signalling is mediated through G proteins and phospholipases and leads to transient increases in cytoplasmic free calcium that subsequently activate the kinase PKC (protein kinase C) and CAMKII (calcium calmodulin mediated kinase II) and the phosphatase calcineurin.

Learn what RNA is and get information about its appearance, bases, function, and properties. Explore the different types of ribonucleic acid.
Liposomes are versatile delivery systems that encapsulate siRNA, enhancing stability and targeted delivery for therapeutic applications.
UCLA life scientists have created an accurate new method to identify genetic markers for many diseases — a significant step toward a new era of personalized medicine, tailored to each person’s DNA and RNA. The powerful method, called GIREMI (pronounced Gir-REMY), will help scientists to inexpensively identify RNA editing sites, genetic mutations and single nucleotide
Transfer RNA
This is an industry innovative automatic nucleic acid extractor, which is compact and lightweight and fits perfectly into the biosafety cabinet. It adopts the magnetic bead method to extract nucleic acid from samples. Through self-developed mixing extraction technology, the liquid and magnetic beads are mixed evenly, and after lysis, nucleic acid adsorption, washing and elution, nucleic acid extraction and purification of DNA and RNA viruses are realized, and finally, high purity nucleic acid is obtained. In addition, the extraction process does not require additional reagents, and the fully automated operation reduces labor costs.

What's the difference between DNA and RNA? DNA, or deoxyribonucleic acid, is like a blueprint of biological guidelines that a living organism must follow to exist and remain functional. RNA, or ribonucleic acid, helps carry out this blueprint's guidelines. Of the two, RNA is more versatile than DNA...
