Serum KLB level is associated with the severity of HBV-related liver diseases and has important diagnostic value for HCC. Therefore, it could be a predictive biomarker for monitoring disease progression.
In-depth research on its processing methods, active ingredients, quality control, pharmacokinetics, pharmacological and toxicological mechanisms, and standardized clinical application is needed. This paper provides a reference for the application and research of mirabilite in the future.
Taken together, this study has unveiled the tumor-promoting role of KLB mediated by its regulation on exosomes secretion through a Rab8a-dependent mechanism. These findings could be exploited to develop novel theranostic targets for prostate cancer.
Furthermore, the results revealed that HDAC3 inhibitor‑mediated acetylated modification led to KLB inactivation, resulting in the blockade of FGF21‑KLB signaling, which further triggered the expression of EMT induction‑related genes in Huh7 cells. In conclusion, the present study demonstrated that aberrant acetylated modification of KLB inhibited FGF21‑KLB signaling, thereby promoting β‑catenin signaling‑driven EMT and HCC metastasis.
