The relationship of Adriamycin sensitivity to oxygen utilization by the cell is unclear. We examined the oxygen uptake and Adriamycin sensitivity of seven human colon carcinoma cell lines under normal aerobic conditions. Adriamycin sensitivity was inversely related to oxygen consumption and lactate dehydrogenase-specific activity.

High drug resistance remains a challenge for chemotherapy against hepatocellular carcinoma (HCC). Combining chemotherapeutic agents with microRNA (miRNA), which simultaneously regulates multiple pathways, offers a promising approach to improve therapeutic efficacy against HCC. Although cationic amphiphilic copolymers have been used to co-deliver these agents, their effectiveness is often limited by low co-encapsulation efficiency and inherent cationic toxicity.

Reactive oxygen species (ROS) play a critical role in regulating various physiological processes. To gain a comprehensive understanding of their distinct functions in different physiological events, it is imperative to detect binary ROS simultaneously. However, the development of the sensing method capable of binary ROS detection remains a significant challenge.

With the rising global cancer burden, the dependency on chemotherapy also rises along with the complication of chemoresistance development. Studies on multi-drug resistant proteins provide a wide range of regulators, although the exact mechanism is not yet clearly understood. Epigenetic modifications play a vital role in the regulation of cellular processes and also in determining the efficacy of cancer therapy by modulating resistance development and tumor progression.

Acquired resistance to chemotherapeutic drugs is the primary cause of treatment failure in the clinic. While multiple factors contribute to this resistance, increased expression of ABC transporters-such as P-glycoprotein (P-gp), breast cancer resistance protein (BCRP), and multidrug resistance proteins-play significant roles in the development of resistance to various chemotherapeutics. We found that Erastin, a ferroptosis inducer, was significantly cytotoxic to NCI/ADR-RES, a P-gp-expressing human ovarian cancer cell line.

Background: Triple-negative breast cancer (TNBC) is an aggressive subtype with limited treatment options and high resistance to chemotherapy. Doxorubicin is commonly used, but its efficacy is limited by variable sensitivity and resistance. Bacopaside II, a saponin compound, has shown anti-cancer potential.
