Abstract
Endogenous and environmental oxidation is increasingly becoming an important factor associated with numerous disorders in both children and adults. The lung is particularly prone to oxidation, as the gas exchange organ is continuously exposed to a great deal of airborne oxidants. Lung oxidation-induced toxicity is a critical clinical problem that is currently lacking cure. For example, treatment for acute respiratory distress syndrome (ARDS), a common type of acute diffuse lung injury, is strictly supportive. Alkylating chemotherapeutics and many methyl chemicals can cause acute or chronic lung injury, which is also difficult to treat. Many new approaches are being tried to improve the treatment of lung oxidation and alkylation; one of these is the use of DNA repair proteins, such as base excision repair proteins that are largely involved in repairing DNA damage caused by oxidation and alkylation. Recent advances have revealed their promising potential for treating oxidation toxicity. Here we discuss discoveries that have led to this possibility, including pioneering research into the cellular signaling transduction and molecular mechanisms of DNA repair proteins. In conclusion, when combined with other therapeutic measures such as anti-oxidant chemicals and enzymes, DNA repair proteins may have great potential for treating acute and chronic lung toxicity induced by oxidation and alkylation.

Melatonin Signaling in Health and Disease
Melatonin regulates a multitude of physiological functions, including circadian rhythms, acting as a scavenger of free radicals, an anti-inflammatory agent, a modulator of mitochondrial homeostasis, an antioxidant, and an enhancer of nitric oxide bioavailability. AANAT is the rate-limiting enzyme responsible for converting serotonin to NAS, further converted to melatonin by ...read more
Programmed Cell Death Genes in Oncology: Pioneering Therapeutic and Diagnostic Frontiers
Programmed Cell Death (PCD) is recognized as a pivotal biological mechanism with far-reaching effects in the realm of cancer therapy. This complex process encompasses a variety of cell death modalities, including apoptosis, autophagic cell death, pyroptosis, and ferroptosis, each of which contributes to the intricate landscape of cancer development and ...read more
