Aldo-keto reductase 1C3 (AKR1C3) is correlated with tumor development and chemotherapy resistance. The catalytic activity of the enzyme has been recognized as one of the important factors in inducing anthracycline (ANT) resistance in cancer cells. Inhibition of AKR1C3 activity may provide a promising approach to restore the chemosensitivity of ANT-resistant cancers. Herein, a series of biaryl-containing AKR1C3 inhibitors has been developed. The best analogue selectively blocked AKR1C3-mediated reduction of doxorubicin (DOX) in MCF-7 transfected cell models. Furthermore, co-treatment of significantly synergized DOX cytotoxicity and reversed the DOX resistance in MCF-7 cells overexpressing AKR1C3. The potential synergism of over DOX cytotoxicity was demonstrated and . Our findings indicate that inhibition of AKR1C3 potentially enhances the therapeutic efficacy of ANTs and even suggests that AKR1C3 inhibitors may serve as effective adjuvants to overcome AKR1C3-mediated chemotherapy resistance in cancer treatment.

Human aldo-keto reductase 1C3 (AKR1C3) is a steroid modifying enzyme involved in cancer progression. Here, A-ring modified 17α-picolyl and 17()-picolinylidene androstane derivatives are shown to inhibit AKR1C3 activity . None of the androstane derivatives have off-target affinity for the androgen receptor, based on a fluorescence assay in yeast cells.

Aldo-keto reductases (AKRs) are a superfamily of NAD(P)(H)-dependent oxidoreductases (phase I enzymes) that reduce aldehydes and ketones to primary and secondary alcohols, respectively. Four percent of xenobiotic biotransformation has been attributed to AKRs, although this is likely an underestimate because this is based on their ability to act as carbonyl reductases. AKRs also have an emerging role in nitroreduction.

Epidemiological studies and in vivo animal models have shown that exposure to PFAS can lead to cardiovascular toxicity and promote atherosclerosis. In this study, we explored the effects of PFOA and PFOS exposure on lipid accumulation in macrophages and analyzed critical markers of foam cell formation, which are early precursors of atherosclerotic lesions. Our results demonstrate that PFOS and PFOA enhance lipid and cholesterol accumulation in human U937-derived macrophages, which is characteristic of foam cells.

Introduction: Osteosarcoma (OS) is an invasive and lethal malignancy showing a low 5 year survival rate, underscoring the need for identifying new therapeutic targets and their inhibitors to enhance prevention and treatment strategies.
Methods: In this study, in vitro experiments including CCK-8 assay, anchorage-independent growth assays, and plate cloning assays were used to detect the anti-proliferation ability of natural compound tangeretin towards OS cells. An integrated approach was performed including WGCNA and network pharmacology to identify the key genes of tangeretin for the treatment of OS.

Esophageal adenocarcinoma (EAC) is the predominant subtype of esophageal cancer (EC) in high-income countries, and radioresistance is one of the key factors for the poor prognosis. In this study, we successfully established a radioresistant EAC in vitro model. Aldo-keto reductase 1C3 (AKR1C3) was identified as a promising regulator of radioresistance by RNA-seq analysis and subsequent functional studies.
