Anticancer activity of RecQL1 helicase siRNA in mouse xenograft models

RecQL1 DNA repair helicase: A potential tumor marker and therapeutic target against hepatocellular carcinoma.

RecQL1 in the human RecQ DNA helicase family participates in DNA repair and recombination pathways in cell cycle replication. Immunohistochemical analysis of human hepatocellular carcinoma (HCC) tissues showed that RecQL1 expression is strongly correlated with histological grade and MIB-1 indices of HCC, and that the expression was greater in simple HCCs inducing extranodular growth or portal v...

Radiolabeled liposome imaging determines an indication for liposomal anticancer agent in ovarian cancer mouse xenograft models

Liposomal anticancer agents can effectively deliver drugs to tumor lesions, but their therapeutic effects are enhanced in only limited number of patients. Appropriate biomarkers to identify responder patients to these liposomal agents will improve their treatment efficacies. We carried out pharmacological and histopathological analyses of mouse xenograft models bearing human ovarian cancers (Ca...

RECQL1 and WRN DNA repair helicases: potential therapeutic targets and proliferative markers against cancers

RECQL1 and WRN helicases in the human RecQ helicase family participate in maintaining genome stability, DNA repair, replication, and recombination pathways in the cell cycle. They are expressed highly in rapidly proliferating cells and tumor cells, suggesting that they have important roles in the replication of a genome. Although mice deficient in these helicases are indistinguishable from wild...

Tunicamycin potentiates cisplatin anticancer efficacy through the DPAGT1/Akt/ABCG2 pathway in mouse Xenograft models of human hepatocellular carcinoma.

Hepatocellular carcinoma is highly chemoresistant, and ATP-binding cassette subfamily G member 2 (ABCG2) is thought to play a critical role in this drug resistance. The present study aims to develop effective therapeutic strategies to decrease ABCG2 expression level and to surmount drug resistance in hepatocellular carcinoma chemotherapy. First, we verified a positive correlation between the AB...
