Smad anchor for receptor activation (SARA) is known as Smad cofactor that interacts directly with Smad2/3 and functions to recruit Smad2/3 to the TGF-beta receptor. SARA plays an essential role in TGF-beta-induced Smad2 activation and it may modulate TGF-beta signaling through regulating the balance between Smad2 and Smad3. SARA also functions as an anchor for catalytic subunit of protein phosp...
Transforming growth factor (TGF)-β/Smad signaling plays an important role in colon cancer development, progression and metastasis. In this study we demonstrated that the microRNA-130a/301a/454 family is up-regulated in colon cancer tissues compared to paired adjacent normal mucosa, which share the same 3'-untranslational region (3'-UTR) binding seed sequence and are predicated to target Smad4. ...
Members of the transforming growth factor-beta family (e.g. TGF-beta, BMP and activin) are critical regulators of tooth morphogenesis. The basic TGF-beta signaling engine consists of a receptor complex that activates Smads and a Smad-containing complex that controls transcription of the downstream target genes. Little is known about the expression of endogenous Smads during tooth morphogenesis....
Invasion and metastasis are the major causes of death in patients with esophageal squamous cell carcinoma (ESCC). Epithelial-mesenchymal transition (EMT) is a critical step in tumor progression and transforming growth factor-β1 (TGF-β1) signaling has been shown to play an important role in EMT. In this study, we investigated how TGF-β1 signaling pathways contributed to EMT in three ESCC cell li...
We previously demonstrated that blocking hepatocyte growth factor (HGF) receptor/c-Met signaling inhibited arthritis and articular bone destruction in mouse models of rheumatoid arthritis (RA). In the present study, we investigated the role of c-Met signaling in osteoblast differentiation using the C2C12 myoblast cell line derived from murine satellite cells and the MC3T3-E1 murine pre-osteobla...
During development and in pathological contexts such as fibrosis and cancer progression, epithelial cells can initiate a complex transcriptional reprogramming, accompanied by dramatic morphological changes, in a process named 'epithelial-mesenchymal transition' (EMT). In this transition, epithelial cells lose their epithelial characteristics to acquire mesenchymal properties and increased motil...
Administration of bleomycin (BM) produces inflammation and fibrosis of the lung in humans and experimental animals. The molecular defects by which BM induces these pathological effects have not been studied in detail. We studied the expression of Smad family proteins, key molecules involved in mediating transforming growth factor (TGF)-beta signaling from the cell membrane to the nucleus, durin...
Bone morphogenetic proteins (BMP) have been implicated in the development of bone metastases in prostate cancer. In this study, we investigated the role which BMP-9 played in prostate cancer and found that the expression of BMP-9 was decreased or absent in prostate cancer, particularly in the foci of higher grade disease. We further investigated the influence of BMP-9 on the biological behavior...
