Abstract
Kin17 DNA and RNA binding protein (Kin17) is an extremely conserved nuclear protein that is almost expressed in every type of mammal cells. Recently, Kin17 has been implicated into the regulation of tumorigenesis of diverse human cancers. However, its functions in thyroid cancer (TC) are still largely unexplored. Kin17 mRNA and protein level were tested by qRT-PCR and western blot, respectively. Effects of Kin17 on TC cell proliferation were estimated by colony formation assay and flow cytometry analysis in vitro as well as by in vivo tumor growth experiment. TC cell migratory and invasive capacities were assessed via wound-healing and transwell experiments. Epithelial-mesenchymal transition (EMT)-related proteins (E-cadherin and N-cadherin) and p38 MAPAK signaling pathway-related proteins (p-p38, p38, Cyclin D1, and p27) were examined via western blot. Kin17 was remarkably increased in TC tissue samples and cell lines at both mRNA and protein levels compared to normal tissue and control cell line. Knockdown of Kin17 obviously repressed TC cell proliferation, arrested cell cycle, and inhibited TC cell migration and invasion in vitro, while overexpression of Kin17 produced opposite effects. Kin17 knockdown suppressed p38 MAPK signaling pathway, while Kin17 overexpression activated this pathway. Treatment of p38 agonist (p79350) abolished the repressive effects of sh-Kin17 on TC cell proliferation, migration, and invasion, as well as on p38 pathway. Kin17 knockdown was also found to enhance the sensitivity of Doxorubicin of TC cells. In addition, Kin17 knockdown in vivo also markedly repressed TC tumor growth and p38 pathway. Kin17 functioned as an oncogene of TC by activating p38 MAPK signaling pathway.

Abstract
This study aimed to elucidate the potential effects of diallyl trisulfide (DATS) on human papillary-thyroid-carcinoma BCPAP cells and its underlying mechanisms. DATS is an organosulfur compound derived from garlic. In this study, we demonstrated that compared with the solvent control, DATS treatment at concentrations of 5, 10, and 20 μΜ decreased cell survival rates of BCPAP cells to 84.51 ± 2.67, 57.16 ± 1.18, and 41.22 ± 1.19% respectively. DATS also caused cell-cycle arrest at G0/G1 phase, and the proportion of cells arrested in G0/G1 phase rose from 68.8 ± 8.38 to 80.4 ± 8.38%, which eventually resulted in cell apoptosis through a mitochondrial apoptotic pathway in BCPAP cells. Further evidence showed that DATS activated ERK, JNK, and p38, members of the MAPK family. Moreover, ERK and JNK inhibitors partially reversed apoptosis in BCPAP cells induced by DATS treatment. Taken together, our results demonstrated that DATS exerted an apoptosis-inducing effect on papillary-thyroid-cancer cells via activation of the MAPK signaling pathway, which shed light on a prospective therapeutic target for thyroid-cancer treatment.
