Far upstream element-binding protein 1 (FUBP1) is a single-stranded nucleic acid-binding protein that binds to the Far Upstream Element (FUSE) sequence and is involved in important biological processes, including DNA transcription, RNA biogenesis, and translation. Recent studies have highlighted the significance of aberrant expression or mutations in FUBP1 in the development of various tumors, with FUBP1 overexpression often indicating oncogenic roles in different tumor types. However, it is worth noting that recent research has discovered its tumor-suppressive role in cancer, which is not yet fully understood and appears to be tissue- or context-dependent.

Rationale: The consistency evaluation of generic drugs is important for the overall reformation of drug registration in China. In this study, we used meropenem as a model drug to explore the key techniques for clinical consistency evaluation by studying the plasma protein binding (PPB) ratio of different preparations. Because the free portion of drug is the effective part in vivo, it is essential to measure the free drug concentration in the circulatory system.

Circulating free androgens are important indicators for a variety of diseases, so accurate determination of these hormones in serum is of great clinical significance. However, there are still many challenges for the accurate quantification of free androgens using mass methods because of their very low levels and complex interferences in serum, as well as the high serum protein binding rate and high nonspecific binding (NSB) rate. Here, an HPLC-MS/MS method coupled with magnetic solid phase extraction (MSPE) and in-situ derivatization was developed to quantify two free androgens-free testosterone (FT) and free androstenedione (FA)-in human serum simultaneously and accurately.
