Article Title: Integrative Quantitative Analysis of Platelet Proteome and Site-Specific Glycoproteome Reveals Diagnostic Potential of Platelet Glycoproteins for Liver Cancer.
Article Snippet: The role of peripheral blood platelets as indicators of cancer progression is increasingly recognized, and the significance of abnormal glycosylation in platelet function and related disorders is gaining attention.. However, the potential of platelets as a source of protein site-specific glycosylation for cancer diagnosis remains underexplored.. In this study, we proposed a general pipeline that integrates quantitative proteomics with site-specific glycoproteomics, allowing for an in-depth investigation of the platelet glycoproteome.

Article Title: Adipocytes promote cancer stemness properties in oral squamous cell carcinoma through C3/C3AR axis and sphingolipid metabolism.
Article Snippet: There is convincing evidence that being overweight or having obesity is associated with an increased risk of developing oral squamous cell carcinoma (OSCC).. Despite OSCC frequently spread to the cervical lymph nodes, where adipose tissue is the predominant tissue within the microenvironment, it is still largely unknown whether adipocytes could contribute to the formation of oral cancer stem cells (CSCs) niche during the oral carcinogenesis.. Here, we report that adipocytes promote the CSCs phenotype of OSCC cells through the activation of complement C3 (C3).
