  • Acetyl-CoA Synthetase 1 regulates global histone propionylation and metabolic stress responses. bioRxiv : the preprint server for biology Garcia, K. C., Zhu, C., Morrison, A. J. 2026

    Abstract

    Cells and organisms are often exposed to various metabolic environments that require adaptive responses for survival. One common way cells adapt to fluctuating nutrient environments is through regulated transcription of metabolic genes. Intermediary metabolites, such as acetyl-CoA, produced by metabolic pathways, serve as cofactors for histone post-translational modifications, which in turn regulate gene expression. However, increasing evidence shows that non-acetyl acyl-CoAs, such as propionyl-CoA, participate in gene regulation during metabolic stress. In this report, we find that histone propionylation functions as a global response to glucose starvation. Furthermore, we find that Acetyl-CoA Synthetase 1 (Acs1) binds chromatin and is the primary enzyme responsible for generating propionyl-CoA in the nucleus. Together, our findings reveal that Acs1-mediated histone propionylation constitutes a novel pathway for metabolic adaptation, linking nutrient availability to chromatin modification.

  • Revolutionizing Postdoctoral Training Using the Social Ecological Model: Insights and Experiences from the Propel Scholars. GEN biotechnology Hayes, C. A., Headley, C. A., Nava, A. R., Vizcarra, E. A., Garcia, K. C., Mullen, M. M., Morales, J. F., Venida, A. C., Follis, S. 2024; 3 (4): 196-206

    Abstract

    The dissatisfaction within the postdoctoral training phase has led to the drastic reduction in the number of U.S. citizens pursuing postdoctoral positions within the biological and biomedical sciences fields. Even more so, there is an obvious disparity in not only the recruitment but the retention among underrepresented groups to pursue careers as academic scientists. The proposed social-ecological model and National Institute of Health advisory committee suggests reforming the postdoctoral training phase to overcome these downward trends and disparities. Importantly, some programs like the Stanford Propel Postdoctoral Program were integrating this framework and recommendations without knowledge that they would be released 2 years later. The goal of the Propel Program is to provide social, cohort, financial, and institutional support to diverse cohorts of postdoctoral trainee to diversify the professoriate. Within this piece, several of the Propel scholars come together to provide their perspectives on how the Propel Program has benefited their postdoctoral training experience.
