KLHL21 suppresses gastric tumourigenesis via maintaining STAT3 signalling equilibrium in stomach homoeostasis.

Objective: Precancerous metaplasia transition to dysplasia poses a risk for subsequent intestinal-type gastric adenocarcinoma. However, the molecular basis underlying the transformation from metaplastic to cancerous cells remains poorly understood.

Design: An integrated analysis of genes associated with metaplasia, dysplasia was conducted, verified and characterised in the gastric tissues of patients by single-cell RNA sequencing and immunostaining.

Integrase-deficient lentivirus: opportunities and challenges for human gene therapy.

Lentiviruses are powerful tools for gene delivery and have been widely used for the dissection of gene functions in both replicating and quiescent cells. Recently, lentiviruses have also been used for delivering target sequences in gene therapy. Although the lentiviral system provides sustained exogenous gene expression, serious concerns have been raised due to its unfavorable insertion-mediated mutagenesis effect, thereby resulting in the silencing or activation of some unexpected genes.
