- Smad6 suppresses the growth and self-renewal of hepatic progenitor cells.
- Ding ZY, Liang HF, Jin GN, Chen WX, Wang W, Datta PK, Zhang MZ, Zhang B, Chen XP.Author information Hepatic Surgery Centre, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, China.AbstractActivation of hepatic progenitor cells (HPCs) is commonly observed in chronic liver disease and Wnt/β-catenin signaling plays a crucial role in the expansion of HPCs. However, the molecular mechanisms that regulate the activation of Wnt/β-catenin signaling in the liver, especially in HPCs, remain largely elusive. Here, we reported that ectopic expression of Smad6 suppressed the proliferation and self-renewal of WB-F344 cells, a HPC cell line. Mechanistically, we found that Smad6 inhibited Wnt/β-catenin signaling through promoting the interaction of C-terminal binding protein (CtBP) with β-catenin/T-cell factor (TCF) complex to inhibit β-catenin mediated transcriptional activation in WB-F344 cells. We used siRNA targeting β-catenin to demonstrate that Wnt/β-catenin signaling was required for the proliferation and self-renewal of HPCs. Taken together, these results suggest that Smad6 is a regulatory molecule which regulates the proliferation, self-renewal and Wnt/β-catenin signaling in HPCs. J. Cell.

- TNF-α Upregulates Sclerostin Expression in Obese Mice Fed a High-Fat Diet.
- Baek K, Hwang HR, Park HJ, Kwon A, Qadir AS, Ko SH, Woo KM, Ryoo HM, Kim GS, Baek JH.Author information Department of Molecular Genetics, School of Dentistry and Dental Research Institute, Seoul National University, Seoul, Korea; Department of Pharmacology, College of Dentistry and Research Institute of Oral Science, Gangneung-Wonju National University, Gangwondo, Korea.AbstractSclerostin decreases bone mass by antagonizing the Wnt signaling pathway. We examined whether obesity-induced bone loss is associated with the expression of sclerostin. Five-week-old male mice were assigned to one of two groups (n = 10 each) and fed either a control diet (10% kcal from fat; CON) or a high-fat diet (60% kcal from fat; HF) for 12 weeks. Thex final body weight and whole body fat mass of the HF mice were higher than those of the CON mice. The distal femur cancellous bone mineral density and bone formation rate was lower in HF mice than in CON mice. The percent erosion surface was higher in the HF mice than the CON mice. The serum levels and femoral osteocytic protein expression levels of tumor necrosis factor-α (TNF-α) were significantly higher in HF mice than in CON mice. Sclerostin mRNA levels and osteocytic sclerostin protein levels in femoral cortex were also higher in HF mice than in CON mice. Sclerostin expression in MLO-Y4 osteocytes increased with TNF-α treatment, and TNF-α-induced sclerostin expression was blocked by the inhibition of NF-κB activation. Chromatin immunoprecipitation and a luciferase reporter assay demonstrated that NF-κB directly binds to the NF-κB binding elements on the mouse sost promoter and stimulates sclerostin expression. These results support a model in which, in the context of obesity or other inflammatory diseases that increase the production of TNF-α, TNF-α upregulates the expression of sclerostin through NF-κB signaling pathway, thus contributing to bone loss.

- Connective Tissue Growth Factor (CTGF/CCN2) Negatively Regulates BMP-2 Induced Osteoblast Differentiation and Signaling.
- Mundy C, Gannon M, Popoff SN.Author information Department of Anatomy and Cell Biology, Temple University School of Medicine, Philadelphia, Pennsylvania.AbstractConnective tissue growth factor (CTGF/CCN2) and bone morphogenetic protein (BMP)-2 are both produced and secreted by osteoblasts. Both proteins have been shown to have independent effects in regulating osteoblast proliferation, maturation and mineralization. However, how these two proteins interact during osteoblast differentiation remains unknown. In this study, we utilized two cell culture model systems, osteoblasts derived from CTGF knockout (KO) mice and osteoblasts infected with an adenovirus which over-expresses CTGF (Ad-CTGF), to investigate the effects of CTGF and BMP-2 on osteoblast development and function in vitro. Contrary to a previously published report, osteoblast maturation and mineralization were similar in osteogenic cultures derived from KO and WT calvaria in the absence of BMP-2 stimulation. Interestingly, in KO and WT osteoblast cultures stimulated with BMP-2, the KO osteoblasts exhibited enhanced osteoblast differentiation. This increase in osteoblast differentiation was accompanied by increased protein levels of phosphorylated Smad 1/5/8 and mRNA expression levels of bone morphogenetic protein receptor Ib. We also examined osteoblast differentiation in cultures that were infected with an adenoviral-CTGF vector (Ad-CTGF) and in controls. Continuous over-expression of CTGF resulted in decreased osteoblast maturation and mineralization in both unstimulated and BMP-2 stimulated cultures. Impaired osteoblast differentiation in cultures over-expressing CTGF was accompanied by decreased protein levels of phosphorylated Smad 1/5/8. Collectively, the data from these studies demonstrate that CTGF acts to negatively regulate BMP-2 induced signaling and osteoblast differentiation, and warrant additional studies to determine the precise mechanism(s) responsible for this effect.
