However, findings on the sex-specific impacts of these enzymes and transporters are often scattered, highlighting the need for a comprehensive and up-to-date overview of knowledge in this area. This review compiles and analyzes existing data on sex differences in the expression and activity of clinically relevant hepatic drug-metabolizing enzymes and transporters across species, such as cytochrome P450s, UDP-glucuronosyltransferase, carboxylesterases, P-glycoprotein, breast cancer resistance protein, multidrug resistance-associated protein, organic anion-transporting polypeptides and organic cation transporters. It also summarizes how these differences influence clinical pharmacokinetics, adverse drug reactions, and drug dosing regimens. Furthermore, we explore potential underlying mechanisms, including the influence of sex hormones, sex chromosomes and lifestyle-related factors. Lastly, we discuss clinical implications and future directions in the field, highlighting the urgent need for more human-centered research to clarify the sex-specific impact on drug metabolism and transport in human.

Due to its asymptomatic nature in early stages, HCC is often diagnosed at advanced stages when treatment options are limited. Despite being a potentially curative option, liver transplantation remains hindered by high costs and donor scarcity, further compounded by suboptimal long-term success rates.

Morphological assessment and hematoxylin–eosin staining revealed thymic atrophy in cachexic HCC mice. Single-cell RNA sequencing of thymic stromal cells showed a reduction in medullary thymic epithelial cells (mTECs) II and III in cachexic mice. Autoimmune regulator (Aire) downregulation was accompanied by decreased expression of tissue-restricted antigens in mTECs. T cells from cachexic HCC mice induced organ-specific inflammation and T-cell infiltration in multiple organs of tumor-free mice. Following anti-mouse PD-1 antibody treatment, the incidence of inflammation in multiple organs markedly increased in cachexic HCC mice and in tumor-free mice that had received T cells from the cachexic HCC mice. Flow cytometry and immunofluorescence analyses revealed enrichment of thymic monocytic myeloid-derived suppressor cells (M-MDSCs) in cachexic HCC mice. M-MDSCs infiltrated the thymus in cachexic mice with cancer, and they induced apoptosis of mTECs from tumor-free mice &lt;em&gt;in vitro&lt;/em&gt; via nitric oxide production. Transfer of M-MDSCs led to inflammatory cell infiltration in multiple organs and thymic involution in tumor-free mice without affecting body weight.
