miR-124-3p regulates the involvement of Ptpn1 in testicular development and spermatogenesis in mouse

Lvjing Luo, Lishuang Sun, Shu Li, Huiting Liu, Zhengyu Chen, Shi Huang, Yinyin Mo, Genliang Li

Summary: This study analyzed the expression of Ptpn1 and miR-124-3p in testicular tissues of mice and investigated their regulatory relationship. The results showed that Ptpn1 expression was up-regulated in adult mouse testis compared to juvenile mouse testis, while miR-124-3p expression showed an opposite pattern. Further analysis suggested that the down-regulation of miR-124-3p may contribute to the high expression of Ptpn1 in adult mouse testis.

Increased histone acetylation is the signature of repressed state on the genes transcribed by RNA polymerase III

Aneeshkumar Gopalakrishnan Arimbasseri, Ashutosh Shukla, Ashis Kumar Pradhan, Purnima Bhargava

Summary: Covalent modifications, such as histone acetylations, are associated with transcriptionally active chromatin regions. Pol III-transcribed genes are repressed under stress conditions, and this repression is linked to increased histone acetylations. A nucleosome in the upstream region of the SNR6 gene plays a regulatory role during repression, with different dynamics of H3K9 and H3K14 acetylations. The increase in acetylations on this nucleosome may be part of the signaling mechanisms preparing cells for stress-related repression and reactivation.

Beta-mannosidosis in a domestic cat associated with a missense variant in MANBA

Martin L. Katz, James Cook, Charles H. Vite, Rebecca S. Campbell, Lyndon M. Coghill, Leslie A. Lyons

Summary: This article describes a neurologic evaluation of a 6-month-old cat with progressive motor impairment. Whole genome sequence analysis identified a mutation in the MANBA gene that resulted in the loss of beta-mannosidase activity and caused beta-mannosidosis. Postmortem examination revealed significant accumulation of vacuolar inclusions in the cat's brain tissue.

The CRISPR Revolution: Unraveling the mysteries of Life's genetic code

Zohreh Harsij, Zahra Ghafoorzadeh, Elahe Goharian

Summary: A biotechnological revolution is triggered by the versatility, accuracy, and efficiency of CRISPR-Cas systems. Diagnosing nucleic acid biomarkers using CRISPR is a highly sensitive method. It can detect a wide range of infectious and non-infectious diseases, mutations, and CRISPR deletions associated with genetic disorders. Additionally, this technology has applications in protein and micromolecule testing. However, despite its many contributions to biomedical science, CRISPR technology has negative impacts on the health of living organisms, environmental conditions, and population structures.
