This protein is involved in the WNT signaling pathway acting as a coreceptor for WNT …” Loss of function mutation in the gene for low density lipoprotein receptor related protein 5 has been shown to cause osteoporosis. WNT role associated with LRP5 is that is controls multiple aspect of skeletal development. Pathways activated by WNT increase bone mass through stimulation of pre- osteoblast replication. LRP5 bind to several different molecules such as WNT and DKK and co receptor protein Frizzled
The Wnts are secreted glycoproteins that makes a large family of nineteen proteins in humans hinting to a daunting complexity of signaling regulation, function and biological functions. To date major signaling branches downstream of the Fz receptor have been identified including a canonical or Wnt/β-catenin dependent pathway and the non-canonical or β-catenin-independent pathway which can be further divided into the Planar Cell Polarity and the Wnt/Ca2+ pathways, and these branches
an extremely detailed explanation of those individual subunits of the complex interacting specifically with different activators and repressors to regulate specific signaling pathways for example nuclear receptors interacts with Med1, MAP kinase pathway requires Med23, CDK8 interacts with myc and Med15 is required for TGFb signaling however the molecular mechanism of mediator regulatory function is not well understood. It carries on explaining the importance of Med12 in vivo pro... ... middle of
is used because the tissue formed encapsulates the enamel organ. The invagination between two “lobes” of the dental sac gives rise to dental papilla. According to Ten Cate’s Oral Histology textbook, when the enamel knot is formed, there are many signaling molecules that are expressed, including Bmp2, Bmp4, Bmp7, Fgf4, Fgf9, Wnt10b, Slit1 and Shh. The enamel knot signals are formed at the future cusps (example: molars) Eventually, the enamel organ will form the enamel, the dental papilla will form
In this essay I am going to talk about the lungs and the stages of their embryonic development. I chose the lungs because they are one of the most important organs for survival -they supply oxygen to cells and release carbon dioxide to the atmosphere. This essay will mostly focus on the different stages of the lung development- the embryonic, the pseudoglandular, the canalicular, the terminal sac, and the postnatal stage. The successful maturation of the lungs requires the completion of both biochemical
Induced pluripotent stem cells (iPSCs) have the capacity to have a widespread impact on biomedical research and therapeutic approaches to an array of diseases and disorders. These stem cells are of extreme potency because they can self-renew in culture while maintaining the capability to become virtually any cell type (Zhu and Huangfu, 2013). While there are many ethical concerns regarding embryonic stem cells, induced pluripotent stem cells arise from adult somatic cells that can be reprogrammed
