Histone serotonylation is a permissive modification that enhances TFIID binding to H3K4me3

…, NV Bhanu, B Zhang, YHE Loh, A Ramakrishnan… - Nature, 2019 - nature.com
Chemical modifications of histones can mediate diverse DNA-templated processes,
including gene transcription 1 , 2 – 3 . Here we provide evidence for a class of histone post-…

Hypoxic niches attract and sequester tumor-associated macrophages and cytotoxic T cells and reprogram them for immunosuppression

…, Z Chen, VJ Marallano, C Brusco, A Ramakrishnan… - Immunity, 2023 - cell.com
Glioblastoma (GBM), a highly lethal brain cancer, is notorious for immunosuppression, but
the mechanisms remain unclear. Here, we documented a temporospatial patterning of tumor-…

Dopaminylation of histone H3 in ventral tegmental area regulates cocaine seeking

…, P Zhong, LA Farrelly, ACW Smith, A Ramakrishnan… - Science, 2020 - science.org
Vulnerability to relapse during periods of attempted abstinence from cocaine use is hypothesized
to result from the rewiring of brain reward circuitries, particularly ventral tegmental area …

[HTML][HTML] Early life stress alters transcriptomic patterning across reward circuitry in male and female mice

CJ Peña, M Smith, A Ramakrishnan, HM Cates… - Nature …, 2019 - nature.com
Abuse, neglect, and other forms of early life stress (ELS) significantly increase risk for psychiatric
disorders including depression. In this study, we show that ELS in a postnatal sensitive …

Long-term behavioral and cell-type-specific molecular effects of early life stress are mediated by H3K79me2 dynamics in medium spiny neurons

…, S Sidoli, O Issler, A Godino, A Ramakrishnan… - Nature …, 2021 - nature.com
Animals susceptible to chronic social defeat stress (CSDS) exhibit depression-related
behaviors, with aberrant transcription across several limbic brain regions, most notably in the …

…, A Minier-Toribio, EM Hicks, A Ramakrishnan… - Science …, 2023 - science.org
Opioid use disorder (OUD) looms as one of the most severe medical crises facing society.
More effective therapeutics will require a deeper understanding of molecular changes …

Cocaine self-administration alters transcriptome-wide responses in the brain's reward circuitry

…, YHE Loh, I Purushothaman, A Ramakrishnan… - Biological …, 2018 - Elsevier
Background Global changes in gene expression underlying circuit and behavioral dysregulation
associated with cocaine addiction remain incompletely understood. Here, we show how …
