Role of the transcription factor SOX8 in hepatocellular carcinoma development and lymph node metastasis

Xiong Teng, Tian-Man Li, Kai Peng, Yuhua Li et autres

Background: in HCC LNM. Methods: knockdown and overexpression were assessed in HCC cell lines via proliferation, migration, and invasion assays. Changes in epithelial-mesenchymal transition (EMT) markers (E-cadherin, N-cadherin, Vimentin) were examined by Western blot. Results: drives EMT to promote HCC cell invasiveness …

Generation of high-repetition-rate, high-power, few-cycle, 2-µm laser pulses with a single-stage all-fiber nonlinear compressor

Zhen Yuan, Kejian Yang, Yang Li, Jingjie Hao et autres

We demonstrate a high-repetition-rate, high-power, few-cycle 2-µm laser employing a single-stage, all-fiber nonlinear pulse compressor. The compressor consists of three cascaded dispersion-compensating fibers that are spliced, with group velocity dispersions of −0.095 ps 2 /m, 0.137 ps 2 /m, and −0.076 ps …
