BACKGROUND The transforming growth factor-beta (TGF-β) signaling pathway plays a critical role in promoting tumor growth. TGF-β1was found to be overexpressed in anaplastic thyroid cancer (ATC). We therefore tested our hypothesis that targeting TGF-β1 inhibits tumorigenesis of ATC cells. MATERIAL AND METHODS Effects of TGF-β1 stimulation or TGF-β1 inhibition by small interfering RNA (TGF-β1siRNA...
Primordial Germ Cells (PGCs) are unipotent precursors of the gametes. PGCs can give rise to a type of pluripotent stem cells in vitro that are called embryonic germ (EG) cells. PGCs can also acquire such pluripotency in vivo and generate teratomas. Under specific culture conditions, PGCs can be reprogrammed to embryonic germ cells which are capable of expression of key pluripotency marker...
OBJECTIVE Anaplastic thyroid cancer (ATC) is one of the most lethal human malignancies. However, the molecular mechanisms of ATC invasion are poorly understood. The transforming growth factor-beta (TGF-β) signaling pathway plays a critical role in promoting tumor metastasis. TGF-β1 was found to be overexpressed in anaplastic thyroid cancer (ATC). We therefore tested our hypothesis that targeted...
The dual effect of the ubiquitous inflammatory cytokine transforming growth factor beta1 (TGF beta) on cellular proliferation and tumor metastasis is intriguing but complex. In epithelial cell- and neural cell-derived tumors, TGF beta serves as a growth inhibitor at the beginning of tumor development but later becomes a growth accelerator for transformed tumors. The somatostatin (SST) signaling...
The Six1 homeodomain protein is a developmental transcription factor that has been implicated in tumor onset and progression. Our recent work shows that Six1 overexpression in human breast cancer cell lines is sufficient to induce epithelial-to-mesenchymal transition (EMT) andmetastasis. Importantly, Six1-induced EMT and metastasis are dependent on TGF-b signaling. The TGF-b pathway plays a dua...
Human respiratory syncytial virus (RSV) is a lung tropic virus causing severe airway diseases including bronchiolitis and pneumonia among infants, children, and immuno-compromised individuals. RSV triggers transforming growth factor-β (TGF-β) production from lung epithelial cells and TGF-β facilitates RSV infection of these cells. However, it is still unknown whether RSV infected myeloid cells ...
TGF-β1 is enriched in the tumor microenvironment and acts as a key inducer of epithelial to mesenchymal transition (EMT) in lung cancer. The NOTCH signaling pathway is conserved across species and is an essential pathway for development, cell differentiation, and cancer biology. Dysregulation of Notch signaling is a common feature of non-small cell lung cancer (NSCLC) and is correlated with poo...
Transforming growth factor-beta (TGF-β) plays a crucial role in cancer during development and metastasis. The TGF-β signaling pathway begins with the binding of active to receptor type II, which ultimately leads expression target genes nucleus. In this study, 56 compounds from Allium cepa were docked against transforming I II (TGFBR II) identify small molecular weight capable firmly kinase doma...
Clinically, there is a great need for small molecule inhibitors that could control pathogenic effects of transforming growth factor (TGF-beta) and/or modulate effects of TGF-beta in normal responses. Inhibition of TGF-beta signaling would be predicted to enhance re-epithelialization of cutaneous wounds and reduce scarring fibrosis. Selective small molecule inhibitors of the TGF-beta signaling p...
Aim and Background: Chronic myeloid leukemia (CML) is a clonal myeloproliferative disorder with cytogenetic characterization of the abnormal Philadelphia chromosome. This chromosome results from a reciprocal translocation between chromosomes 9 and 22. This is an important signaling pathway in the process of cancer cell proliferation and apoptosis, as well as the pathogenesis of TGF-β disease, i...
