Aging Cells Rejuvenated When Hydrogen Sulfide Gives Splicing Factors a Lift

For aging cells, the Fountain of Youth gushes with hydrogen sulfide, which isn’t exactly convenient. Yes, in the laboratory, hydrogen sulfide has been shown to reverse some of the manifestations of cellular senescence, a state in which cells cease to divide but linger on, secreting inflammatory factors and driving age-related maladies. The hydrogen sulfide, however, is usually delivered by hydrogen sulfide donors in nonphysiological conditions. Could hydrogen sulfide’s benefits&mdash
