BUFFALO, NY- February 27, 2024 – A new research paper was published in Aging (listed by MEDLINE/PubMed as "Aging (Albany NY)" and "Aging-US" by Web of Science) Volume 16, Issue 3, entitled, “The anti-aging effect of vitamin D and vitamin D receptor in Drosophila midgut.”
Adult stem cells are pivotal for maintaining tissue homeostasis, and their functional decline is linked to aging and its associated diseases, influenced by the niche cells’ environment. Age- and cancer-related reduction of vitamin D and its receptor levels are well documented in human clinical studies. However, the mechanisms through which the vitamin D/vitamin D receptor (VitD/VDR) pathway contributes to anti-aging and extends life expectancy are not well understood. In this new study, researchers Joung-Sun Park, Hyun-Jin Na and Yung-Jin Kim from Pusan National University and Korea Food Research Institute aimed to determine the protective role of the vitamin D/vitamin D receptor pathway in differentiated enterocytes (ECs) during intestinal stem cell (ISC) aging.
“This study aimed to determine the protective role of VitD/VDR in differentiated ECs during ISC aging using the adult Drosophila intestine model.”
By utilizing a well-established Drosophila midgut model for stem cell aging biology, the researchers revealed that vitamin D receptor knockdown in ECs induced ISC proliferation, EC death, ISC aging, and enteroendocrine cell differentiation. Additionally, age- and oxidative stress-induced increases in ISC proliferation and centrosome amplification were reduced by vitamin D treatment. In conclusion, this study provides direct evidence of the anti-aging role of the VitD/VDR pathway, involving protecting ECs during aging, and provides valuable insights for exploring the molecular mechanisms underlying enhanced healthy aging in Drosophila.
“Our findings suggest a direct evidence of the anti-aging role of the vitamin D/vitamin D receptor pathway and provides insights into the molecular mechanisms underlying healthy aging in Drosophila.”

About Aging-US:
Aging publishes research papers in all fields of aging research including but not limited, aging from yeast to mammals, cellular senescence, age-related diseases such as cancer and Alzheimer’s diseases and their prevention and treatment, anti-aging strategies and drug development and especially the role of signal transduction pathways such as mTOR in aging and potential approaches to modulate these signaling pathways to extend lifespan. The journal aims to promote treatment of age-related diseases by slowing down aging, validation of anti-aging drugs by treating age-related diseases, prevention of cancer by inhibiting aging. Cancer and COVID-19 are age-related diseases.
