Hyperthermia and cisplatin combination therapy promotes caspase-8 accumulation and activation to enhance apoptosis and pyroptosis in cancer cells.

Background: Hyperthermia can play a synergistic role with chemotherapy in combination therapy. Although the association between caspase activation, apoptosis, and pyroptosis have been published for both cisplatin (CDDP) and hyperthermia therapies independently, the interactions between these molecular pathways in combination therapy are unknown. The present study aimed to investigate the possible interactions between caspase 8 activation, apoptosis, and pyroptosis in combination therapy.

Co-delivery of Cas9 mRNA and guide RNAs for editing of LGMN gene represses breast cancer cell metastasis.

Legumain (or asparagine endopeptidase/AEP) is a lysosomal cysteine endopeptidase associated with increased invasive and migratory behavior in a variety of cancers. In this study, co-delivery of Cas9 mRNA and guide RNA (gRNA) by lipid nanoparticles (LNP) for editing of LGMN gene was performed. For in-vitro transcription (IVT) of gRNA, two templates were designed: linearized pUC57-T7-gRNA and T7-gRNA oligos, and the effectiveness of gRNA was verified in multiple ways.
