Project description:Skin is the largest organ in the body and comprises several types of cells. The intercellular plasticity of keratinocytes, fibroblasts, and skin adipocytes contributes to wound healing and dermal adipogenesis. Although keratinocyte activates dermal adipose tissue (dWAT) differentiation upon hair follicular cycle, regulating dWAT hyperplasia through keratinocyte reprogramming is still unknown. We used the CRISPR/Cas9 base editor to induce single nucleotide polymorphisms in Forkhead-box N1 (Foxn1) and identified the p.L19M variant that induced the formation of a thicker dWAT regardless of hair follicular cycle or wound healing. Foxn1 p.L19M activates Wnt5β through transcriptional activity. Wnt5β signaling induces the conversion of dWAT dermal fibroblasts into adipose precursor cells (APCs) and promotes APC adipocyte differentiation through keratinocyte epithelial-mesenchymal transition (EMT) and adipogenic signaling. Wnt5β is involved in the entire process of dWAT hyperplasia through APC supply and adipogenic signaling as a single factor. Foxn1 p.L19M and Wnt5β are expressed in keratinocytes, and a keratinocyte-derived adipogenic signal is critical for dermal adipogenesis. In addition, transient expression of Foxn1 p.L19M or Wnt5β using adeno-associated virus reproduced dermal adipocyte hyperplasia in mice. Considering the increasing importance of dWAT in functions such as the immune response, wound healing, hair follicle growth, and temperature control, this finding has potential applications in skin regeneration

Project description:White adipose tissue (WAT) plays a central role in lipid storage and systemic energy, lipid, and glucose homeostasis. Understanding the intricacies of adipocyte formation could inform therapies for obesity and metabolic disorders. We have identified the POZ/BTB and AT Hook Containing Zinc Finger 1 (PATZ1) protein as an adipogenic transcription factor through an unbiased high-throughput cDNA screen for transcriptional modulators of adipogenesis. PATZ1 is expressed by both human and mouse adipocyte precursor cells (APCs) and adipocytes, and in cell models, PATZ1 expression promotes adipogenesis through a mechanism dependent on protein-protein interaction and DNA binding. Both adipocyte-specific and APC-specific ablation of PATZ1 in mice leads to decreased fat mass and hypertrophied adipocytes. Genome-wide PATZ1 DNA binding analyses using ChIP-Seq suggest PATZ1 facilitates adipogenesis through interactions with transcription factor machinery at the promoter regions of critical early adipogenic factors and histone modifiers. Purification of the PATZ1 complex showed that General Transcription Factor 2I (GTF2I) associates with PATZ1 in a differentiation-dependent manner. Downregulation of GTF2I levels during adipogenesis markedly augments PATZ1 adipogenic function, suggesting a repressive interaction between GTF2I and PATZ1. These findings identify PATZ1 as a regulator of both adiposity and adipocyte differentiation programs and advance our understanding of the complex transcriptional mechanisms underlying adipose tissue development and homeostasis.

Project description:To investigate the effect of ZNF395 on adipogenesis, we tested whether ZNF395 enhance cell conversion from human dermal Fibroblast (FIB) to Adipocyte (ADP). PPARG2 was reported as a master regulator and can induce adipogenesis in non-adipogenic fibroblasts. We transduced PPARG2 with or without ZNF395 in FIB with lentivirus. Interestingly, co-transduction of PPARG2 and ZNF395 showed higher occurrence of adipocyte-like cells as compared with PPARG2 alone. Moreover, genes related with lipid metabolic process and lipid transport was significantly up-regulated in combination of PPARG2 and ZNF395. These results suggest that ZNF395 co-ordinate the transcriptional regulatory pathway with PPARG2, necessary for the induction of adipogenesis. Total RNA was obteined from human dermal fibroblast transduced with mock lentivirus vector (FIB_ctrl), PPARG2 (FIB_PPARG2) and co-transduced with PPARG2 and ZNF395 (FIB_PPARG2+ZNF395).

Project description:we aimed to screen candidate genes of adipocyte/osteoblastogenesis using human mesenchymal stem cells (hMSCs) at 3, 5, and 7 days through RNA-Seq technique. The 275 significantly differentially expressed genes (DEGs) were identified simultaneously shared by two anecdotes. Furthermore, we confirmed that ANKRD1 (ankyrin repeat domain 1) facilitated adipogenesis and weaked osteoblastogenesis via RNA interference (RNAi), and IGF1 (insulin like growth factor 1) simultaneously enhancted adipo-osteoblastogenesis. This study would provide the potential molecular switches for the study of the balance of adipo-osteoblastogenesis and therapy of metabolic bone disease osteoporosis.
