Abstract Breast cancer, a predominant global health issue, requires ongoing exploration of new therapeutic strategies. Palbociclib (PAL), a well-known cyclin-dependent kinase (CDK) inhibitor, plays a critical role in breast cancer treatment. While its efficacy is recognized, the interplay between PAL and cellular autophagy, particularly in the context of the RAF/MEK/ERK signaling pathway, remains insufficiently explored. This study investigates PAL’s inhibitory effects on breast cancer using both in vitro (MCF7 and MDA-MB-468 cells) and in vivo (tumor-bearing nude mice) models. Aimed at elucidating the impact of PAL on autophagic processes and exploring the potential of combining it with trametinib… More > Graphic Abstract

Abstract Osteosarcoma is the most common primary bone malignancy manifested predominantly in children and young adults. Studies indicate that miR-107 is involved in the pathogenesis of osteosarcoma and that tropomyosin 1 (TPM1) acts as a tumor suppressor in many types of cancer. In this study, we analyzed the effect of miR-107 on human osteosarcoma cells and investigated the mechanism in which TPM1 is involved. miR-107 expression in human osteosarcoma tissues and cells was analyzed in quantitative real-time PCR (qRT-PCR). Human osteosarcoma (U2OS) cells were transfected with miR-107 mimic, inhibitor, or scramble controls to evaluate the effect… More >
