Circadian rhythms and breast cancer: unraveling the biological clock’s role in tumor microenvironment and ageing

Frontiers in Immunology, Год журнала: 2024, Номер 15

Опубликована: Июль 30, 2024

Breast cancer (BC) is one of the most common and fatal malignancies among women worldwide. Circadian rhythms have emerged in recent studies as being involved pathogenesis breast cancer. In this paper, we reviewed molecular mechanisms by which dysregulation circadian genes impacts development BC, focusing on critical clock genes, brain muscle ARNT-like protein 1 (BMAL1) locomotor output cycles kaput (CLOCK). We discussed how rhythm disruption (CRD) changes tumor microenvironment (TME), immune responses, inflammation, angiogenesis. The CRD compromises surveillance features activities effectors, including CD8+ T cells tumor-associated macrophages, that are important an effective anti-tumor response. Meanwhile, review, discuss bidirectional interactions: age rhythms, aging further increases risk through reduced vasoactive intestinal polypeptide (VIP), affecting suprachiasmatic nucleus (SCN) synchronization, ability to repair damaged DNA, weakened immunity. These complex interplays open new avenues toward targeted therapies combination drugs with chronotherapy potentiate response while reducing progression for better outcomes.

Targeting BMAL1 reverses drug resistance of acute myeloid leukemia cells and promotes ferroptosis through HMGB1-GPX4 signaling pathway

Journal of Cancer Research and Clinical Oncology, Год журнала: 2024, Номер 150(5)

Опубликована: Май 4, 2024

Abstract Purpose Acute myeloid leukemia (AML) is a refractory hematologic malignancy that poses serious threat to human health. Exploring alternative therapeutic strategies capable of inducing modes cell death, such as ferroptosis, holds great promise viable and effective intervention. Methods We analyzed online database data collected clinical samples verify the expression function BMAL1 in AML. conducted experiments on AML proliferation, cycle, chemotherapy resistance by overexpressing/knocking down using assays MDA detection BODIPY 581/591 C11 staining. validated transcriptional regulation HMGB1 through ChIP assay, luciferase RNA level detection, western blotting. Finally, we confirmed results our at animal level. Results up-regulation an observed phenomenon patients. Furthermore, there existed strong correlation between elevated levels inferior prognosis individuals with found knocking inhibited growth blocking cycle. Conversely, overexpressing promoted proliferation. Moreover, research revealed ferroptosis cells BMAL1-HMGB1-GPX4 pathway. can enhance efficacy certain first-line cancer drugs, including venetoclax, dasatinib, sorafenib. Conclusion Our suggest plays crucial regulatory role drug resistance, ferroptosis. could be potential important target for
