The Claim
The long non-coding RNA LOC100507600, transcribed antisense to LCT, is positively correlated with lactase mRNA levels in human jejunum (R²=0.73), and its knockdown reduces LCT mRNA by 25% in intestinal cells, indicating a direct regulatory role in lactase expression.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
A specific RNA molecule called LOC100507600, which is produced near the lactase gene, is associated with higher levels of lactase mRNA in the human small intestine. Reducing this RNA molecule decreases lactase mRNA by 25% in intestinal cells.
See the scientific wording
The long non-coding RNA LOC100507600, transcribed antisense to LCT, is positively correlated with lactase mRNA levels in human jejunum (R²=0.73), and its knockdown reduces LCT mRNA by 25% in intestinal cells, suggesting it plays a direct regulatory role in lactase expression.
A long RNA molecule made in the opposite direction of the lactase gene blocks a molecular barrier that normally stops the gene from being turned on. When this RNA is present, the barrier disappears, allowing a distant switch to connect to the lactase gene and turn it on strongly. When this RNA is removed, the barrier returns and the gene stays off.
What the research says
1 studyStudy: Lactase non-persistence is directed by DNA variation-dependent epigenetic aging
Scientists found that a hidden RNA molecule near the lactase gene helps keep lactase levels high—when they reduced it, lactase dropped by 25%. The study confirms that nearby RNA plays a key role in making lactase, just like the claim says.
