WebTTF1 gene copy number analysis using the TCGA HCC dataset. To assess whether TTF1 gene copy number variations affected TTF1 gene expression, we extracted copy number data from the TCGA dataset. A strong correlation between copy number and TTF1 expression was observed in tumor tissues (R=0.583, P<0.001; Fig. 1C).. Increased … WebD. Origin of syncytial elements. The giant and multinucleated cells forming either pseudo-syncytia or real syncytia scored positive for the pneumocyte markers Surfactant-A (a, x20), TTF1 (b, x20) and Napsin (c, x20), indicative of their epithelial origin.

WebTTF1 was first identified as a thyroid-specific DNA-binding activity which interacted with the rat thyroglobulin gene. Human TTF1 is a single polypeptide of 371 amino acids that is … TTF-1 positive cells are found in the lung as type II pneumocytes and club cells. In the thyroid, follicular and parafollicular cells are also positive for TTF-1. For lung cancers, adenocarcinomas are usually positive, while squamous cell carcinomas and large cell carcinomas are rarely positive. Small cell carcinomas (of any primary site) are usually positive.
