HELQ Maintains Genome Stability of Primordial Germ Cells by Inhibiting LINE‐1 Expression

The FASEB Journal, Volume 39, Issue 12, 30 June 2025.
HELQ interacts with the histone demethylase KDM4B to maintain the level of H3K9me3 modification in the LINE‐1 region, thus inhibiting its expression and preserving genome stability. HELQ deficiency leads to elevated levels of KDM4B and reduces H3K9me3 modification, which increases LINE‐1 expression and subsequently genome instability in primordial germ

Rare case of bilateral vassal agenesis and AZFc microdeletion: A case report

Men's Health Journal, 2018
Introduction: Bilateral vassal agenesis (CBAVD) is a rare cause of male infertility. Also one of the nonobstructive cause of azoospermia and infertility in men is microdeletion in long arm of Y chromosome. In this case report we have reported a rare case
