Gene Finding Offers New Hope for Cancer Therapy
A groundbreaking study published in Frontiers in Endocrinology has identified the gene SDR42E1 as crucial for vitamin D absorption and metabolism.This discovery holds significant potential for precision medicine, including advancements in cancer treatment.
Vitamin D is vital not only as a nutrient but also as a precursor to calcitriol, a hormone essential for overall health. It plays a key role in regulating calcium and phosphate absorption for bone health, and influences cellular growth, muscle function, nerve cells, and the immune system.
“We demonstrate that blocking or inhibiting the SDR42E1 gene can selectively halt the growth of cancer cells,” stated Dr. Georges Nemer, an associate professor at Hamad Bin Khalifa University in Qatar and the study’s led author.
Dr.Nemer and his team were motivated by prior research linking a specific mutation in the SDR42E1 gene on chromosome 16 to vitamin D deficiency. This mutation leads to a premature interruption, rendering the gene inactive.
Utilizing CRISPR/CAS9 gene editing technology, the researchers rendered the SDR42E1 gene inactive in a colorectal cancer cell line, HCT116. these cells typically exhibit high SDR42E1 expression, suggesting its importance for their survival.
Following the introduction of the defective gene version, the viability of the cancer cells decreased by 53%. Furthermore, the expression levels of 4,663 “downstream” genes were altered, indicating that SDR42E1 acts as a critical molecular switch in numerous vital cellular processes.
Many of these affected genes are implicated in cancer-related cellular signaling and the absorption and metabolism of cholesterol-like molecules.
These findings suggest that inhibiting this gene could selectively destroy cancer cells while sparing healthy neighboring cells.
“Our results pave the way for new avenues in precision oncology, although clinical translation necessitates rigorous validation and extensive growth,” commented dr. Nafiz Hendi, a professor at Middle East University in Jordan and another lead author of the study.
Beyond its potential in targeting cancer cells through vitamin D deprivation, the study suggests SDR42E1 has a dual function. Artificially increasing its levels in specific tissues through genetic technology could also offer therapeutic benefits.
background: Vitamin D, often called the “sunshine vitamin,” is crucial for maintaining calcium and phosphate levels in the body, which are essential for building and maintaining strong bones. its role extends beyond bone health, impacting immune function, cell growth, and the nervous system. Vitamin D deficiency is a widespread issue, linked to various health problems including osteoporosis and potentially certain cancers. The discovery of SDR42E1’s role in vitamin D absorption and metabolism provides a new molecular target for understanding and treating conditions related to vitamin D levels.
Context: Precision medicine aims to tailor medical treatment to the individual characteristics of each patient. By understanding the genetic underpinnings of nutrient absorption and metabolism, researchers can develop more targeted and effective therapies. The identification of SDR42E1 as a key player in vitamin D pathways opens doors for personalized approaches to managing vitamin D levels and potentially treating diseases where these pathways are dysregulated.
Ancient Trends: Research into vitamin D’s health benefits has evolved significantly over the decades. Initially recognized for its role in preventing rickets, scientific understanding has expanded to encompass its broader impact on immunity, chronic disease prevention, and cellular regulation.the development of genetic editing tools like CRISPR/CAS9 has accelerated the pace of discovery, allowing scientists to investigate the precise molecular mechanisms involved in vitamin D’s action.
