Sex-specific gene and isoform expression characterizes hippocampal aging in rhesus macaques

Victoria Harper-Alexander, Sam Peterson, Saida Sadikova, Steven G. Kohama, Daniel Ramos Ram

This study identifies sex-specific gene and isoform expression changes in hippocampal aging of rhesus macaques and finds shared transcriptional signatures with Alzheimer's disease.

Aging macaques bridge the translational gap in perivascular space biology

William A. Liguore, Daniel L. Schwartz, Juan A. Piantino, Avanthika Rajendran, Greg Jensen, Joshua A. Karpf, Mykyta M. Chernov, Randall L. Woltjer, Steven G. Kohama, Lisa C. Silbert, Alison R. Weiss

This study shows that aging rhesus macaques exhibit age-dependent perivascular space burden, mirroring human patterns, and validates MRI-detected structures as perivascular spaces.

Modulation of neural gene networks by estradiol in old rhesus macaque females.

Rita P. Cervera‐Juanes, Kip D. Zimmerman, Larry Wilhelm, Dongqin Zhu, Jessica Bodie, Steven G. Kohama, Henryk F. Urbanski

This study examines how estradiol affects gene expression and DNA methylation in the brains of old rhesus macaques after ovariectomy and hormone treatment, identifying molecular networks and gene changes linked to estrogen depletion.
