Wolfe-Simon et al. (Research Articles, 3 June 2011, p. 1163; published online 2 December 2010) reported that bacterium GFAJ-1 can substitute arsenic for phosphorus in its macromolecules, including DNA and proteins. If such arseno-DNA exists, then much of the past century of work with arsenate and phosphate chemistry, as well as much of what we think we know about metabolism, will need rewriting.

POLYPHARMACY AND CANCER: А NEW VISION FOR SKIN CANCER PATHOGENESIS-PHOTOTOXICITY AND PHOTOCARCINOGENICITY DUE TO NITROSAMINE CONTAMINATION DURING TELMISARTAN/ TAMSULOSIN INTAKE.

The toxicokinetics of nitrosamines remain a mystery to this day, though it appears that the role of nitrosamines in potentiating the generation of mutations required for the onset of skin cancer continues to be a significant concern. Nitrosamines are mutagens, genotoxic substances, and mediators of phototoxicity/carcinogenicity, whose long-term daily usage, in the context of polypharmacy, can result in the parallel appearance of heterogeneous forms of skin cancer: keratinocytic and melanocytic. But a number of clinical observations suggest that it is the nitrosamines that potentiate the multiple occurrences of skin cancer over the years, or recurrences of skin cancer localized in areas exposed to solar radiation.

5-Aminolevulinate synthase (ALAS) is a PLP-dependent enzyme that catalyzes the production of 5-aminolevulinate from succinyl-CoA and glycine. Its ability to catalyze the essentially irreversible - bond formation has significant potential in chemoenzymatic synthesis of α-amino ketones. Native ALAS, unfortunately, is extremely substrate-selective, and this seriously limits its synthetic utility.

The presence of () infection has been indicated to have a protective influence on esophageal cancer (EC) in some studies, but its specific impact on the risk of esophageal squamous cell carcinoma and esophageal adenocarcinoma remains inconclusive. This manuscript comment addresses the recent study by López-Gómez . Despite it was a retrospective observational study without a control group, this study revealed a notably low prevalence of infection among EC patients, indicating a potential association between and EC in Spain.
