Colorectal cancer (CRC) is one of the leading causes of cancer death worldwide, with most mortalities being caused by metastases. However, the underlying molecular mechanism of CRC metastases remains largely unknown. Emerging evidence has shown the role of the tripartite motif family, especially tripartite motif protein 6 (TRIM6), in carcinogenesis. In this study, we used CRC cell lines with TRIM6 knockdown and overexpression to investigate the function of TRIM6 in CRC metastasis. We found that TRIM6 promotes CRC cell migration and invasion both and . TRIM6 knockdown slows down the migration and invasion processes, whereas TRIM6 overexpression accelerates CRC cell migration and invasion. TRIM6 is potentially the upstream regulatory factor for signal transducer and activator of transcription 3 (STAT3) the suppressor of cytokine signaling 2 (SOCS2). A total of 70 samples from patients with CRC further confirmed that TRIM6 expression level is positively correlated with STAT3 phosphorylation and negatively correlated with SOCS2 expression. Therefore, TRIM6 could be a potential therapeutic target for CRC metastasis.

Colorectal cancer (CRC) is among the most common cancer types for both sexes. Tripartite motif 36 (TRIM36) has been reported to be aberrantly expressed in several cancer types, suggesting its involvement in cancer progression. However, the role of TRIM36 in the colorectal carcinogenesis remain unknown.

During skeletal muscle unloading, phosphoinositide 3-kinase (PI3K), and especially PI3K gamma (PI3Kγ), can be activated by changes in membrane potential. Activated IP3 can increase the ability of Ca to enter the nucleus through IP3 receptors. This may contribute to the activation of transcription factors that initiate muscle atrophy processes.

Introduction: Cancer cachexia (CC) is characterized by weight loss with specifically reduced skeletal muscles and adipose tissues in patients with late-stage cancer. Dihydroartemisinin (DHA), an effective antimalarial derivative of artemisinin, has been demonstrated to have anti-inflammatory and antitumor properties.
Materials And Methods: This study examined the effects of DHA on the Lewis lung carcinoma (LLC)-induced CC mouse model.

Purpose: Cardiac inflammation is a basic pathological process of diabetic cardiomyopathy (DCM). Inflammatory response is closely related to pyroptosis, which is a recently identified programmed cell death type. Curcumin (CUR) is a polyphenol extracted from turmeric and has been reported to be crucial in alleviating pyroptosis in DCM.
