Hedgehog (Hh) is first described as a genetic mutation that has “spiked” phenotype in the cuticles of Drosophila in later 1970s. Since then, Hh signaling has been implicated in regulation of differentiation, proliferation, tissue polarity, stem cell population and carcinogenesis. The first link of Hh signaling to cancer was established through discovery of genetic mutations of Hh receptor gene PTCH1...
Nicotine, the chemical compound which causes cigarette addiction, could be responsible for some lung cancers. Evidence for genetic influence on smoking behavior and nicotine dependence has prompted a search for susceptibility genes. Furthermore, assessing the impact of sequence variants on smoking-related diseases is important to public health. Recently, the locus containing two genes encoding nicotine...
DEC1, also known as SHARP-2 or Stral3, is an important molecule in embryonic differentiation and a bHLH type transcriptional regulator. It has recently been identified to be abundantly expressed in several human tumors and might play an important role in tumor development. But its expression in gastric carcinoma is unknown. In this study we show that DEC1 was frequently expressed in six gastric carcinoma...
