Differential Expression and Distribution of Slco4a1 and Slco1b2 in an Internal Environment Disorder-induced Hepatocellular Carcinoma Mouse Model
Haoxuan Luo, Yang Xie, Shan Huang, Yu ZhangObjective:
This study aims to enhance the understanding of underlying mechanisms and potential therapies of the solute carrier organic anion (SLCO) transporter family in internal environment disorder (IED)-induced hepatocellular carcinoma (HCC). This could lead to new therapeutic strategies and offer new directions for the creation of new patents for HCC treatment products.
Methods:
The orthotopic transplantation (OT), IED and IED-based OT (IED-OT) mouse models were established. Expression patterns of Slco4a1 and Slco1b2 were determined using reverse transcriptionquantitative polymerase chain reaction (RT-qPCR), western blotting (WB) and immunohistochemistry (IHC) in various tissues, including lung, stomach, liver, spleen, kidney, colon, small intestine, HCC tissues and adjacent non-cancerous tissues.
Results:
Animals exhibited symptoms, including weight loss, lethargy, chills, dyspnea, altered hair texture, and gastrointestinal disturbances, confirming the successful establishment of the IED model. The analysis demonstrated differential expression and tissue-specific distribution of Slco4a1 and Slco1b2, which are associated with IED-induced changes. These alterations potentially disrupt organ transport functions, thereby promoting the development of HCC. Additionally, they suggest a role in rebalancing the tumor microenvironment and mitigating damage resulting from abnormal substance accumulation.
Conclusions:
Changes in SLCO expression and distribution induced by IED may play pivotal roles in the development of HCC. These findings contribute insights that could inform novel therapeutic strategies against HCC.
