Neurogenic Decisions Require a Cell Cycle Independent Function of The

Accumulating data suggest that cell cycle dynamics play a major role in the regulation of this balance. Here we show that the G2/M cell cycle regulator CDC25B phosphatase is required in mammals to finely tune neuronal production in the neural tube. We show that in chick neural progenitors, CDC25B activity favors fast nuclei departure from the apical surface in early G1, stimulates neurogenic divisions and promotes neuronal differentiation. We design a mathematical model showing that within a limited period of time, cell cycle length modifications cannot account for changes in the ratio of the mode of division. Using a CDC25B point mutation that cannot interact with CDK, we show that part of CDC25B activity is independent *For correspondence: of its action on the cell cycle.

2012 Annual Report Stanford Institute for Stem Cell Biology and Regenerative Medicine
2012 ANNUAL REPORT STANFORD INSTITUTE FOR STEM CELL BIOLOGY AND REGENERATIVE MEDICINE DOLOR SET AMET 1 MESSAGE FROM THE DIRECTOR The year 2012 was a pivotal one. We now have several discoveries coming from the Institute that are either at, or will soon be at, the clinical trial stage. With this in mind, we need to beef up our ability to carry out stem cell therapies at Stanford. The key to any stem cell therapy is to identify and isolate pure populations of stem cells in a sterile facility so that those cells can be administered to patients. I’m pleased to say that we now nearly have pledges of support to establish a Stem Cell Therapy Center at Stanford, which will allow us to isolate pure populations of stem cells and will make such clinical trials possible. This is a major partnership of Stanford Medicine: the Institute is partnering with Stanford Hospital, thanks to Amir Rubin, and with Lucille Packard Children’s Hospital, thanks to Chris Dawes. Our first cohort of patients at the new Stem Cell Therapy Center will be women with widespread, metastatic breast cancer. We will obtain their ‘mobilized blood,’ which contains blood-forming stem cells and also circulating cancer cells, and from that we will purify the stem cells of all cancer cells to safely regenerate their blood and immune cells after very high-dose chemotherapy. Years ago, a small clinical trial at Stanford using high-dose chemotherapy and these sorts of purified stem cell transplants led to 33% survival over the last 14 years among women with stage-four 1 breast cancer (while of those that received purified mobilized primary eating cells of the immune system, macrophages. -

Its regulation is complex and while there are many methods available, there is " autophagy currently no single effective way of detecting and monitoring autophagy. It has several " endocrine glands cellular functions that are conserved throughout the body, as well as a variety of different " crinophagy physiological roles depending on the context of its occurrence in the body. Autophagy is also " endocrine diseases involved in the pathology of a wide range of diseases. Within the endocrine system, autophagy has both its traditional conserved functions and specific functions. In the endocrine glands, autophagy plays a critical role in controlling intracellular hormone levels. In peptide-secreting cells of glands such as the pituitary gland, crinophagy, a specific form of autophagy, targets the secretory granules to control the levels of stored hormone. In steroid-secreting cells of glands such as the testes and adrenal gland, autophagy targets the steroid-producing organelles. -

Simulated Microgravity Inhibits Cell Focal Adhesions Leading to Reduced
www.nature.com/scientificreports OPEN Simulated microgravity inhibits cell focal adhesions leading to reduced melanoma cell proliferation and Received: 4 December 2017 Accepted: 18 January 2018 metastasis via FAK/RhoA-regulated Published: xx xx xxxx mTORC1 and AMPK pathways Xin Tan1, Aizhang Xu2,3, Tuo Zhao1, Qin Zhao1, Jun Zhang1, Cuihong Fan1, Yulin Deng1, Andrew Freywald4, Harald Genth5 & Jim Xiang1,2,3 Simulated microgravity (SMG) was reported to afect tumor cell proliferation and metastasis. However, the underlying mechanism is elusive. In this study, we demonstrate that clinostat-modelled SMG reduces BL6-10 melanoma cell proliferation, adhesion and invasiveness in vitro and decreases tumor lung metastasis in vivo. It down-regulates metastasis-related integrin α6β4, MMP9 and Met72 molecules. SMG signifcantly reduces formation of focal adhesions and activation of focal adhesion kinase (FAK) and Rho family proteins (RhoA, Rac1 and Cdc42) and of mTORC1 kinase, but activates AMPK and ULK1 kinases. We demonstrate that SMG inhibits NADH induction and glycolysis, but induces mitochondrial biogenesis. Interestingly, administration of a RhoA activator, the cytotoxic necrotizing factor-1 (CNF1) efectively converts SMG-triggered alterations and efects on mitochondria biogenesis or glycolysis. CNF1 also converts the SMG-altered cell proliferation and tumor metastasis. In contrast, mTORC inhibitor, rapamycin, produces opposite responses and mimics SMG-induced efects in cells at normal gravity. Taken together, our observations indicate that SMG inhibits focal adhesions, leading to inhibition of signaling FAK and RhoA, and the mTORC1 pathway, which results in activation of the AMPK pathway and reduced melanoma cell proliferation and metastasis. Overall, our fndings shed a new light on efects of microgravity on cell biology and human health. -
