AIM: To discover novel biomarkers for early diagnosis, prognosis or treatment of human colorectal cancer. METHODS: i TRAQ 2D LC-MS/MS analysis was used to identify differentially expressed proteins(DEPs) in the human colonic epithelial carcinogenic process using laser capture microdissection-purified colonic epithelial cells from normal colon, adenoma, carcinoma in situ and invasive carcinoma tissues. RESULTS: A total of 326 DEPs were identified, and four DEPs(DMBT1, S100A9, Galectin-10, and S100A8) with progressive alteration in the carcinogenic process were further validated by immunohistochemistry. The DEPs were involved in multiple biological processes including cell cycle, cell adhesion, translation, m RNA processing, and protein synthesis. Some of the DEPs involved in cellular process such as "translation" and "m RNA splicing" were progressively up-regulated, while some DEPs involved in other processes such as "metabolism" and "cell response to stress" was progressively downregulated. Other proteins with up- or down-regulation at certain stages of carcinogenesis may play various roles at different stages of the colorectal carcinogenic process. CONCLUSION: These findings give insights into our understanding of the mechanisms of colorectal carcinogenesis and provide clues for further investigation of carcinogenesis and identification of biomarkers.

Science China Materials 2025年第01期 303-304页

作者： hui huang College of Materials Science and Opto-Electronic Technology Center of Materials Science and Optoelectronics Engineering University of Chinese Academy of Sciences

Organic semiconductors (OSCs), as an emerging next-generation semiconductor material, hold promising prospects in fields such as flexible displays, electronic skins, smart healthcare,and the Internet of Things, due to their excellent flexibility,solution processability, and tunable band structures [1,2]. These molecules are often classified into n-type and p-type, depending on whether the prevalent charge carriers are electrons or holes[3].

AIM: To develop a potent and safe gene therapy for esophageal ***: An expression vector carrying fusion suicide gene(y CDgly TK) and sh RNA against vascular endothelial growth factor(VEGF) was constructed and delivered into EC9706 esophageal cancer cells by calcium phosphate nanoparticles(CPNP). To achieve tumor selectivity, expression of the fusion suicide gene was driven by a tumor-specific human telomerase reverse transcriptase(h TERT) promoter. The biologic properties and therapeutic efficiency of the vector, in the presence of prodrug 5-fluorocytosine(5-FC), were evaluated in vitro and in ***: Both in vitro and in vivo testing showed that the expression vector was efficiently introduced by CPNP into tumor cells, leading to cellular expression of y CDgly TK and decreased VEGF level. With exposure to 5-FC, it exhibited strong anti-tumor effects against esophageal cancer. Combination of VEGF sh RNA with the fusion suicide gene demonstrated strong anti-tumor ***: The sh VEGF-h TERT-y CDgly TK/5-FC system provided a novel approach for esophageal cancer-targeted gene therapy.
