Nicotinamide adenine dinucleotide (NAD) is a critical cofactor in mitochondrial energy production. The NADH/NAD ratio, reflecting the balance between NADH (reduced) and NADoxidized, is a key marker for the severity of mitochondrial diseases. We recently developed a streamlined LC-MS/MS method for the precise measurement of NADH and NAD.

Inflammation disrupts the normal function of granulosa cells (GCs), which leads to ovarian dysfunction and fertility decline. Inflammatory conditions such as polycystic ovary syndrome (PCOS), primary ovarian insufficiency (POI), endometriosis, and age-related ovarian decline are often associated with chronic low-grade inflammation. Nicotinamide mononucleotide (NMN) is an important precursor of NAD and has gained attention for its potential to modulate cellular metabolism, redox homeostasis, and mitigate inflammation.

The hypoxic environment of solid tumors significantly diminishes the therapeutic efficacy of oxygen-dependent photodynamic therapy. Developing efficient photosensitizers that operate photoredox catalysis presents a promising strategy to overcome this challenge. Herein, we report the rational design of two rhenium(I) tricarbonyl complexes ( and ) with electron donor-acceptor-donor configuration.

Background: The wide variability in clinical responses to anti-tumor immunotherapy drives the search for personalized strategies. One of the promising approaches is drug screening using patient-derived models composed of tumor and immune cells. In this regard, the selection of an appropriate in vitro model and the choice of cellular response assay are critical for reliable predictions.
