Summary: Plant secondary metabolites are commonly used in pharmaceutical agents, especially in cancer therapy, to reduce the doses of chemotherapeutic drugs, enhance cell growth inhibition, avoid side effects, and increase cancer cell sensitivity to chemotherapy. They interact with membrane proteins and nucleic acids, inducing apoptosis to overcome multidrug resistance. Consuming dietary supplements containing secondary metabolites may affect the bioavailability, efficacy, and safety of drugs that are substrates of P-glycoprotein.

Summary: Carboplatin-resistant RB cells exhibit higher autophagy activity compared to parent cells, leading to multi-drug resistance. This study introduces a new strategy of inducing autophagy-dependent ferroptosis to eliminate drug-resistant RB cells. The effectiveness and safety of a cell-permeable derivative of itaconate in inducing ferritinophagy-dependent ferroptosis were evaluated.

Summary: Multidrug resistance (MDR) is a major reason for chemotherapy failure, and developing nano-delivery systems for MDR tumors has become important. This review systematically summarizes recent advances in nanotechnology targeting different mechanisms of MDR. However, there are still issues with nano-delivery systems for MDR tumors, such as excessive use of carrier materials, low drug-loading capacity, and limited targeting mechanisms.

Summary: This study found that plant pathogens can develop multidrug resistance (MDR) through metabolomic and efflux activities. The genes encoding ABC and MFS transporters were identified to be associated with MDR in Rhizoctonia solani, and their expression levels were higher in MDR mutant compared to the wild-type strain. Two of these transporters were found to be related to MDR and their roles were confirmed by detecting their protein products and high accumulation of an antifungal compound. These findings contribute to our understanding of fungicide resistance and the development of MDR.

Summary: Vibrio harveyi infection in aquaculture has caused significant economic losses. This study found that a pathogenic strain of V. harveyi could be induced to become a multiple-resistant strain by enrofloxacin, and the mechanism of multidrug resistance was mainly related to the upregulation of the efflux and SOS systems. This research is important for addressing the issue of drug resistance in V. harveyi.

Summary: The development of a lab-on-a-chip system enabled the investigation of drug resistance in leukemia cells using coupled dielectrophoretic detection (DEP-D) and impedimetric counting (IM-C) techniques. Conductivity matching and frequency values allowed for successful discrimination between drug resistant and wild type cells.

Summary: The study found differences in autophagy regulation in resistant hepatocellular carcinoma cells, and demonstrated that the combination of an autophagy inhibitor and a chemotherapeutic agent can promote cell death, reduce drug resistance, and increase reactive oxygen species production and apoptosis induction.

Summary: Identifying effective reversal agents to overcome multidrug resistance is crucial for improving tumor chemotherapy. In this study, a metal cluster-based probe called clusterbody was developed for flow sorting-assisted single-cell mass spectrometry analysis. The clusterbody, synthesized through biomimetic mineralization, selectively recognizes an efflux pump protein and enables high-throughput cell sorting based on fluorescence emitted by the probe. Protein abundance at the single-cell level is determined through precise signal amplification using laser ablation inductively coupled plasma mass spectrometry, allowing quantitative evaluation of reversal agent treatment. This work provides a new approach to identify reversal agents and sheds light on developing combined or synergetic tumor therapy.

Summary: In this study, it was found that elevated expression of TCP1 in acute myeloid leukemia patients was associated with low complete response rate and poor overall survival. Further investigations revealed that TCP1 contributes to drug resistance by inhibiting autophagy and activating the AKT/mTOR signaling pathway. Targeting the TCP1/AKT/mTOR signaling pathway provides a new strategy for overcoming drug resistance in AML.

Summary: This paper provides an overview of the possible role of miRNAs in the molecular mechanisms that lead to multidrug resistance (MDR). miRNAs regulate post-transcriptional processes in the proteosynthetic pathway and may serve as specific effectors or interesting targets for cancer therapy.

Summary: Cancer is a global health problem with high incidence and mortality rates. Osthole, a coumarin compound extracted from Cnidium monnieri (L.) Cuss., has shown promising anticancer effects. Studies have revealed that osthole inhibits cancer cell proliferation, induces apoptosis, suppresses migration and invasion, inhibits angiogenesis, enhances sensitivity to chemotherapy drugs, and reverses multidrug resistance.
