Mouse Ptchd3 (patched domain containing 3) was previously identified as a male germ-cell specific gene. The protein product of this gene has been found on the surface of mouse, rat and human sperm. Since Ptchd3 contains a conserved patched domain, we hypothesize that it functions as a membrane receptor for the hedgehog ligand. Herein, we used a Ptchd3 knockout mouse model to study its function in mouse development and spermatogenesis. We found that Ptchd3 knockout mice were born and lived normally. The fertility and sperm production of knockout males were not changed. Moreover, our data indicated that the expression levels of several hedgehog signaling genes were not affected in mutant testis. Taken together, these findings demonstrate that Ptchd3 is a non-essential gene in mouse development and spermatogenesis.

Obesity has become one of the public health problems that threatens children's health, but its specific etiology and pathogenesis are still unclear. Recently, many long noncoding RNAs (lncRNAs) have been shown to be involved in the occurrence of obesity. However, their roles are still poorly understood.

Background: Copy number variations (CNVs) can contribute to variable degrees of fitness and/or disease predisposition. Recent studies show that at least 1% of any given genome is copy number variable when compared to the human reference sequence assembly. Homozygous deletions (or CNV nulls) that are found in the normal population are of particular interest because they may serve to define non-essential genes in human biology.

Olfactory sensation modulates the TGF-β and insulin signaling pathways to control this developmental decision. Four mutant alleles of daf-25 (abnormal DAuer Formation) were isolated from screens for mutants exhibiting constitutive dauer formation and found to be defective in olfaction.
