Autophagy, an evolutionarily conserved catabolic process involving the engulfment and degradation of non-essential or abnormal cellular organelles and proteins, is crucial for homeostatic maintenance in living cells. This highly regulated, multi-step process has been implicated in diverse diseases including cancer. Autophagy can function as either a promoter or a suppressor of cancer, which makes it a promising and challenging therapeutic target. Herein, we overview the regulatory mechanisms and dual roles of autophagy in cancer. We also describe some of the representative agents that exert their anticancer effects by regulating autophagy. Additionally, some emerging strategies aimed at modulating autophagy are discussed as having the potential for future anticancer drug discovery. In summary, these findings will provide valuable information to better utilize autophagy in the future development of anticancer therapeutics that meet clinical requirements.

Antibody-dependent cell-mediated cytotoxicity (ADCC) by NK cells is a key mechanism in anti-cancer therapies with monoclonal antibodies, including cetuximab (EGFR-targeting) and avelumab (PDL1-targeting). Fc gamma receptor IIIa (FcγRIIIa) polymorphisms impact ADCC, yet their clinical relevance in NK cell functionality remains debated. We developed two complementary flow cytometry assays: one to predict the FcγRIIIa-V158F polymorphism using a machine learning model, and a 15-color flow cytometry panel to assess antibody-induced NK cell functionality and cancer-immune cell interactions.

Erythroleukemia, a complex myeloproliferative disorder presenting as acute or chronic, is characterized by aberrant proliferation and differentiation of erythroid cells. Although nootkatone, a sesquiterpene derived from grapefruit peel and Alaska yellow cedar, has shown anticancer activity predominantly in solid tumors, its effects in erythroleukemia remain unexplored. This study aimed to investigate the impact of nootkatone and its derivatives on erythroleukemia.

Many oncoproteins are important therapeutic targets because of their critical role in inducing rapid cell proliferation, which represents one of the salient hallmarks of cancer. Chronic Myeloid Leukemia (CML) is a cancer of hematopoietic stem cells that is caused by the oncogene BCR-ABL1. BCR-ABL1 encodes a constitutively active tyrosine kinase protein that leads to the uncontrolled proliferation of myeloid cells, which is a hallmark of CML.

Background: BCL-2 was the first gene identified to have antiapoptotic effects, and venetoclax is an oral selective BCL-2 inhibitor, which has great potential in the treatment of patients with acute myeloid leukemia (AML) who are not candidates for intensive therapy. Notably, posaconazole, an oral antifungal drug, is also a strong factor that can affect blood venetoclax concentrations. To the best of our knowledge, the relationship between BCL-2 expression, posaconazole, and venetoclax, as well as their influence on treatment efficacy and the prognosis of patients with AML, has not been reported.
