The EGFR Polymorphism Increased the Risk of Hepatocellular Carcinoma Through the miR-3196-Dependent Approach in Chinese Han Population

Alleviation of doxorubicin adverse effects via loading into various drug-delivery systems: a comparative study

Aim: Drug resistance is still a significant barrier to effective hepatocellular carcinoma therapy. Address the issue of doxorubicin resistance and inter-receptor crosstalk various doxorubicin formulations were investigated. Methods: Hepatocellular carcinoma was carried out using 3-methylechloroanthrene. Animals were then treated with doxorubicin, liposomal doxorubicin, titanium-loaded doxorubicin (TiO2-Dox), lactoferrin-doxorubicin and PEGylated doxorubicin. Biochemical and molecular analyses were assessed. Results: Results have declared a significant alternation of both sodium and potassium concentrations upon 3-methylechloroanthrene administration. Arginase-I and α-L-Fucodinase tumor biomarkers were significantly elevated. C-myc, Hprt-1 and EGFR gene expression were over-expressed. Treatment with the aforementioned treatment regimens significantly modulated all measured parameters. Conclusion: TiO2-Dox, doxorubicin-lactoferrin and PEGylated doxorubicin could be a promising regimen in hepatocellular carcinoma and overcoming the problem of drug resistance.

mTOR: A Potential New Target in Nonalcoholic Fatty Liver Disease

The global prevalence of nonalcoholic fatty liver disease (NAFLD) continues to rise, yet effective treatments are lacking due to the complex pathogenesis of this disease. Although recent research has provided evidence for the “multiple strikes” theory, the classic “two strikes” theory has not been overturned. Therefore, there is a crucial need to identify multiple targets in NAFLD pathogenesis for the development of diagnostic markers and targeted therapeutics. Since its discovery, the mechanistic target of rapamycin (mTOR) has been recognized as the central node of a network that regulates cell growth and development and is closely related to liver lipid metabolism and other processes. This paper will explore the mechanisms by which mTOR regulates lipid metabolism (SREBPs), insulin resistance (Foxo1, Lipin1), oxidative stress (PIG3, p53, JNK), intestinal microbiota (TLRs), autophagy, inflammation, genetic polymorphisms, and epigenetics in NAFLD. The specific influence of mTOR on NAFLD was hypothesized to be divided into micro regulation (the mechanism of mTOR’s influence on NAFLD factors) and macro mediation (the relationship between various influencing factors) to summarize the influence of mTOR on the developmental process of NAFLD, and prove the importance of mTOR as an influencing factor of NAFLD regarding multiple aspects. The effects of crosstalk between mTOR and its upstream regulators, Notch, Hedgehog, and Hippo, on the occurrence and development of NAFLD-associated hepatocellular carcinoma are also summarized. This analysis will hopefully support the development of diagnostic markers and new therapeutic targets in NAFLD.
