Nicotinamide promotes cell survival and differentiation as kinase inhibitor in human pluripotent stem cells

Project description:We examined the effect of nicotinamide on cell survival and differentiation in human pluripotent stem cells. Nicotinamide inhibited the phosphorylation of myosin light chain, suppressed actomyosin contraction, and led to improved cell survival after individualization. Then we analyzed the global gene expression profile after 24 hours of nicotinamide and ROCK inhibitor treatment, and found that the gene expression profile of human embryonic stem cell (hESC) treated with nicotinamide was much different from that of ROCK inhibitor treatment. Further analysis demonstrates that nicotinamide is an inhibitor of multiple kinases, including ROCK and CK1. We demonstrated that nicotinamide affected human embryonic stem cell (hESC) pluripotency and differentiation as a selective kinase inhibitor.

Probing the signaling requirements for naïve human pluripotency by high-throughput chemical screening [WGBS]

Project description:Background: Naïve human embryonic stem cells (hESCs) have been isolated that more closely resemble the pre-implantation epiblast compared to conventional “primed” hESCs, but the signaling principles underlying these discrete stem cell states remain incompletely understood. Methods:Here we performed high-throughput screening using a library of >3,000 well-annotated compounds to identify essential signaling requirements for naïve human pluripotency. Results:We report that MEK1/2 inhibitors can be replaced during maintenance of naïve human pluripotency by inhibitors targeting either upstream (FGFR, RAF1) or downstream (ERK1/2) kinases. Naïve hESCs maintained under these alternative conditions display elevated levels of ERK phosphorylation but retain genome-wide DNA hypomethylation and a transcriptional identity of the pre-implantation epiblast. In contrast, dual inhibition of MEK and ERK promotes efficient primed-to-naïve resetting in combination with PKC, ROCK, and TNKS inhibitors and Activin A. Conclusions: This work demonstrates that induction and maintenance of naïve human pluripotency are governed by distinct signaling requirements.

Transcriptome of bovine trophoblast stem cells (TSC) - in self-renewal and differentiation

Project description:In this study, we examine the transcriptome of bovine TSCs under self-renewal that is sustained by inhibiting RhoA-Rock pathway. Using systems biology of spontaneous differentiation, we identify that TGFB1 induces differentiation of bovine TSCs. We analyse the transcriptome of TSCs under TGFB1 induced differentiation. We also analyze pathways of differentiation that are dependent and independent of RhoA-Rock signaling through analysis of the transcriptome of TSCs exposed to both TGFB1 and ROCK inhibition.

Suspension Differentiation of fibroblast-like pancreatic progenitors

Project description:The purpose of this microarray study was to analyze the initial changes in gene expression that occurred during the first 48 hours of a pancreatic progenitor differentiation scheme. The experiment compared both progenitors cultured normally in 10% SCM with nicotinamide as well as progenitors cultured in suspension for 48 hours in 10% SCM with nicotinamide. For the described conditions, 4 sample pairs were analyzed by microarray, for a total of 8 hybridizations. Each biological set was comprised of one normal and one suspension culture sample. Each set was hybridized only once.

Regulation of gene expression upon inhibition of ROCK and MLCK in mammary epithelial cells

Project description:To understand how mechanical cues regulate cell metabolism, we compared early changes in gene expression in Ras-transformed MCF10AtK1 mammary epithelial cells grown in high cytoskeletal tension conditions (plastics) vs. cells grown in low cytoskeletal tension conditions (inhibition of the non-muscle myosin II regulatory kinases ROCK and MLCK with standard small-molecule inhibitors Y27632 and ML7, respectively). Keywords: Expression profiling by array

The FAM83 family of proteins are anchors for Casein Kinase 1 isoforms through the DUF1669 domain

Project description:The Casein Kinase 1 (CK1) family of Ser/Thr protein kinases are implicated in the regulation of many cellular processes, including cell cycle, circadian rhythm, Wnt and Sonic Hedgehog signalling. Regarded as constitutively active kinases, their regulation in cells is critically important but poorly understood. We report here that members of the FAM83 family of uncharacterized proteins are central regulators of CK1 isoforms in cells. The eight members of the FAM83 family (A-H) interact and co-localize with different CK1 alpha, alpha-like, delta and epsilon isoforms. We demonstrate that the interaction with CK1 isoforms is mediated through a number of residues within a conserved domain of unknown function, termed DUF1669, which characterises the FAM83 family. CK1-binding deficient mutants of FAM83 proteins interfere with the subcellular localization of CK1 isoforms as well as FAM83 proteins themselves and their cellular functions. We propose that DUF1669 be renamed the Polypeptide Anchor of CK1 (PACK1) domain.

Tankyrase inhibition promotes endocrine commitment of hPSC-derived pancreatic progenitors

Project description:To improve β-like cell differentiation from human pluripotent stem cells (hPSCs), we aimed to substitute a mechanistically elusive compound – nicotinamide (NA), which promotes pancreatic progenitor (PP) commitment, with a pathway-specific compound. By performing a low-throughput chemical screening, we demonstrated that tankyrase inhibitors (TNKSi) can replace NA and efficiently generate PPs. Surprisingly, highly selective TNKSi, such as WIKI4, generate PPs that give rise to islet-like populations with improved β-like cell frequencies and glucose responsiveness compared to NA-derived PPs. Characterization of differentially expressed genes (DEG) between WIKI4 and NA treatment revealed that WIKI4-derived PPs expressed higher levels of genes associated with integrin signalling and actin cytoskeleton pathways. Our findings show that compared to NA, WIKI4 treatment promotes changes in cell shape and motility. Together, our results provide novel insights into pancreatic differentiation and a model that better recapitulates native events associated with pancreas and endocrine commitment.

Nicotinamide promotes human pluripotent stem cells differentiation into cardiomyocytes [1]

Project description:Nicotinamide, the amide form of vitamin B3, is essential to maintain the human fetal development. It benefits the ectoderm and endoderm development, but its influence in mesoderm differentiation is elusive. In this study, we reported that nicotinamide regulated the gene expression of cardiovascular system, and it induced functional cardiomyocytes which was independent of canonical WNT signaling. Through a kinase screening, we found that nicotinamide inhibited the activity of P38δ to promote cardiomyocyte differentiation. Furthermore, we compared the gene expression of cardiomyocytes induced by WNT inhibitor IWP-2, nicotinamide or P38 inhibitor SB202190. The results showed that the cardiomyocytes induced by nicotinamide had similar gene expression profile compared with P38 inhibitor, which indicated nicotinamide promoted cardiac differentiation via the inhibition of P38.
