Breast cancer,a predominant global health issue,requires ongoing exploration of new therapeutic ***(PAL),a well-known cyclin-dependent kinase(CDK)inhibitor,plays a critical role in breast cancer *** its efﬁcacy is recognized,the interplay between PAL and cellular autophagy,particularly in the context of the RAF/MEK/ERK signaling pathway,remains insufﬁciently *** 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)*** at elucidating the impact of PAL on autophagic processes and exploring the potential of combining it with trametinib(TRA),an MEK inhibitor,our research seeks to address the challenge of PAL-induced drug ***ﬁndings reveal that PAL signiﬁcantly decreases the viability of MCF7 and MDA-MB-468 cells and reduces tumor size in mice while showing minimal cytotoxicity in MCF10A ***,PAL also induces protective autophagy,potentially leading to drug resistance via the RAF/MEK/ERK pathway *** TRA effectively neutralized this autophagy,enhancing PAL’s anti-tumor efﬁcacy.A combination of PAL and TRA synergistically reduced cell viability and proliferation,and in vivo studies showed notable tumor size *** conclusion,the PAL and TRA combination emerges as a promising strategy for overcoming PAL-induced resistance,offering a new horizon in breast cancer treatment.
