Conversely, increased TGF-β1 and activated TGF-βRI and Smad3 have all been shown to have tumor-promoting effects in experimental systems of human and mouse SCCs.
Immunohistochemical Study of TGF-β1 in Oral Leukoplakia and Oral Squamous Cell Carcinoma: Correlations Between Clinicopathologic Factors and Overall Survival.
Nintedanib dose-dependently inhibited the TGF-β1-induced expression of a panel of pro-fibrotic activation markers in both ADC-TAFs and control fibroblasts derived from uninvolved lung parenchyma, whereas such inhibition was very modest in SCC-TAFs.
Immunohistochemical Expression of CD105 and TGF-β1 in Oral Squamous Cell Carcinoma and Adjacent Apparently Normal Oral Mucosa and its Correlation With Clinicopathologic Features.
We incubated the p16-positive CERV196 and p16-negative HNSCC22B SCC cell lines with EGF and EGF/TGFβ1 (10 ng/ml) and detected E-cadherin, vimentin and β-catenin by immunocytochemistry and enzyme-linked immunosorbent assay after 5, 24 and 96 h.
The transforming growth factor beta-1 (TGFβ-1-509 C/T) polymorphism was inversely associated with having an oral SCCA among persons homozygous for the recessive variant (ORcrude = 0.27; 95% CI 0.09-0.79).
TGF-β1 protein and its receptor I (TGF-βR1) were overexpressed in urine samples in malignant group compared with chronic cystitis and in SQCC group compared with TCC group.
Because transforming growth factor beta1 (TGF-beta1) is up-regulated in OSCC tumors, we examined the relationship between TGF-beta1 signaling and MMP-9 in human OSCC specimens.
A study in this issue of Cancer Cell shows that mice with a targeted knockout of the type II TGFbeta receptor in stratified epithelia specifically develop spontaneous squamous cell carcinomas in the anogenital region, but not in the skin.
A panel of 45 formalin-fixed and paraffin-embedded NSCLC specimens showed positive immunostaining for TGF-beta 1, TGF-beta RI, and TGF-beta RII, with reduced TGF-beta RII in poorly differentiated adenocarcinomas and squamous cell carcinomas and some moderately differentiated adenocarcinomas.
A significant majority of a new series of human SCC cell lines were found to be as sensitive as primary human epidermal keratinocytes to TGF-beta 1 growth inhibition.
TGF-beta 1 and EGF regulation of PTH-rP gene expression in squamous cell carcinomas of gynecologic origin is unique for each cell line studied and different from that in human lung carcinoid cells.
