Objective: To investigate the role of p38 mitogen-activated protein kinase (MAPK) signal transduction pathways in regulating the in vitro invasion of JAR human choriocarcinoma cells induced by phorbol 12-myristate 13-acetate (PMA).
Methods: ELISA was used to detect the kinase activity of the JAR cells in response to PMA stimulation, and the in vitro invasion capabilities of the stimulated cells were observed using transwell assay. Changes in the proliferation and activity of the JAR cells cultured in vitro following PMA treatment were also observed by MTT assay.
Results: p38 MAPK was activated dose-dependently in JAR cells upon the stimulation by PMA, which significantly enhanced the in vitro invasion of the JAR cells, while treatment of the cells with SB203580, a specific inhibitor of p38 MAPK, inhibited the invasion of the cells. The growth of the cells, as observed from the growth curves, was not affected by the treatment of PMA and/or SB203580.
Conclusion: Activation of p38 MAPK signal transduction pathway may enhance the invasion capability of JAR cells, and p38 MAPK inhibition may therefore yield new possibility to control the invasion of choriocarcinoma.

Introduction: Tumor suppressor gene (TSG) inactivation by epigenetic modifications contributes to the carcinogenesis and progression of colorectal cancer (CRC). Expression profiling and CpG methylomics revealed that a forkhead-box transcriptional factor, FOXS1, is downregulated and methylated in CRC.
Objectives: To assess the biological functions and underlying mechanisms of FOXS1 in colorectal cancer.

Introduction: Periodontal diseases are prevalent among middle-aged and elderly individuals. There's still no satisfactory solution for tooth loss caused by periodontal diseases. Human periodontal ligament stem cells (hPDLSCs) is a distinctive subgroup of mesenchymal stem cells, which play a crucial role in periodontal supportive tissues, but their application value hasn't been fully explored yet.

Introduction: Despite of numerous studies of the placenta, some molecular and cellular characteristics, particularly the relationship among different cell types, have not been well understood. We aim to investigate the basic and intricate details of cellular and molecular elements in early and late phase placentas to gain better understanding of the immune regulation of human reproductive process.
Methods: A novel combination of techniques of spatial transcriptomics(ST), multiple immunohistochemistry, and a dual labeling combining immunohistochemistry and (fluorescence in situ hybridization) FISH on normal and ectopic pregnancy and animal models was employed to investigate the placenta at tissue, cell, protein and molecular levels and to trace the fetal and maternal origin of every cell in early and late placentas.
