Comprehensive analysis of skin growth-related hub genes and microenvironment characterization in a mouse expanded skin model.

Background: Mechanical stretch-mediated tissue expansion is effective for obtaining extra skin and soft tissue required for the repair of defects or reconstruction of surface organs. Understanding the cellular and molecular mechanisms and identifying hub genes and key cell types associated with skin expansion could help predict the success of skin growth during expansion procedures.

Methods: We analyzed murine chip sequencing data and single-cell sequencing data available from the Gene Expression Omnibus database.

Hepatitis B virus induces sorafenib resistance in liver cancer via upregulation of cIAP2 expression.

Background: HBV promotes cell survival by upregulating the expression of the cellular inhibitor of apoptosis protein 2 (cIAP2), however whether it is involved in HBV-induced sorafenib resistance in liver cancer remains unclear.

Methods: cIAP2 overexpression and knockdown was adopted to assess the involvement of cIAP2 in HBV-induced sorafenib resistance. Anti-HBV drug lamivudine and Akt inhibitor were used to investigate the impact of HBV replication on cIAP2 expression and sorafenib resistance.
