Aphidicolin is an antibiotic of novel structure produced by the mold Cephalosporium aphidicola. It is a potent inhibitor of cellular deoxyribonucleic acid synthesis, and it also strongly inhibits the growth of herpes simplex virus both in tissue culture and in the rabbit eye. Aphidicolin is active against iododeoxyuridine-resistant herpes virus, and does not itself readily induce the formation of drug-resistant strains of herpesvirus.

Studies in rodent models have been the accepted approach by regulatory agencies to evaluate potential developmental neurotoxicity (DNT) of chemicals for decades. These studies, however, are inefficient and cannot meet the demand for the thousands of chemicals that need to be assessed for DNT hazard. As such, several new approach methods (NAMs) have been developed to circumvent limitations of these traditional studies.

Previous studies suggest a connection between the FA protein FANCD2 and the non-FA protein mechanistic target of rapamycin (mTOR). A recent study showed that mTOR is involved in actin-dependent DNA replication fork restart, suggesting possible roles in the FA DNA repair pathway.

Sensorineural hearing loss (SNHL) is mainly caused by the damage of cochlear hair cells (HCs). As HCs and supporting cells (SCs) do not proliferate in postnatal mammals, the loss of HCs and SCs is irreversible, emphasizing the importance of preserving their numbers to prevent SNHL. It is known that insulin-like growth factor 1 (IGF1) is instrumental in the treatment of SNHL.

Although fungi produce highly structurally diverse metabolites, many of which have served as excellent sources of pharmaceuticals, no fungi-derived agent has been approved as a cancer drug so far. This is despite a tremendous amount of research being aimed at the identification of fungal metabolites with promising anticancer activities. This review discusses the results of clinical testing of fungal metabolites and their synthetic derivatives, with the goal to evaluate how far we are from an approved cancer drug of fungal origin.

Muscle fructose 1,6-bisphosphate aldolase (ALDA) is a glycolytic enzyme which may localize both in nuclei and cytoplasm of cells, however its role in the nuclei is unclear. Here, we demonstrate the links between subcellular localization of ALDA and the cell cycle progression as well as the availability of energetic substrates. Results of our studies indicate that nuclear localization of ALDA correlates with the proliferative activity of the cells and with the expression of Ki-67, a marker of proliferation, both in the KLN-205 (mouse lung cancer cells) and human squamous cell lung cancer cells (hSCC).
