The reverse transcriptase inhibitor 3TC protects against age-related cognitive dysfunction

Project description:Aging is the primary risk factor for most neurodegenerative diseases, including Alzheimer's disease. Major hallmarks of brain aging include neuroinflammation/immune activation and reduced neuronal health/function. These processes contribute to cognitive dysfunction (a key risk factor for Alzheimer's disease), but their upstream causes are incompletely understood. Age-related increases in transposable element (TE) transcripts might contribute to reduced cognitive function with brain aging, as the reverse transcriptase inhibitor 3TC reduces inflammation in peripheral tissues and TE transcripts have been linked with tau pathology in Alzheimer's disease. However, the effects of 3TC on cognitive function with aging have not been investigated. Here, in support of a role for TE transcripts in brain aging/cognitive decline, we show that 3TC: (a) improves cognitive function and reduces neuroinflammation in old wild-type mice; (b) preserves neuronal health with aging in mice and Caenorhabditis elegans; and (c) enhances cognitive function in a mouse model of tauopathy. We also provide insight on potential underlying mechanisms, as well as evidence of translational relevance for these observations by showing that TE transcripts accumulate with brain aging in humans, and that these age-related increases intersect with those observed in Alzheimer's disease. Collectively, our results suggest that TE transcript accumulation during aging may contribute to cognitive decline and neurodegeneration, and that targeting these events with reverse transcriptase inhibitors like 3TC could be a viable therapeutic strategy.

Mass spectrum for identifying the interacting proteins of telomerase reverse transcriptase

Project description:The 293T cells overexpressing human telomerase reverse transcriptase (hTERT) were lysed and co-immunoprecipitation was performed using hTERT antibody. Then protein mass spectrum was conducted in order to identify the hTERT-interacting proteins.

Evolution of a Reverse Transcriptase to Map N1-Methyladenosine in Human mRNA

Project description:Chemical modifications on mRNA are increasingly recognized as a critical regulatory layer of the flow of genetic information, but quantitative tools to monitor RNA modifications in a whole-transcriptome and site-specific manner are lacking. Here we describe a versatile directed evolution platform that rapidly selects for reverse transcriptases that install mutations during reverse transcription at sites of a given type of RNA modification, allowing for site-specific identification of the modification. To develop and validate the platform, we evolved the HIV-1 reverse transcriptase against N1-methyladenosine (m1A). Iterative rounds of selection yielded reverse transcriptases with both robust read-through and high mutation rates at m1A sites. We apply the evolved reverse transcriptase to identify thousands of statistically confident m1A sites in human mRNA, some of which can be detected in antibody-free RNA-seq libraries. Together, this work develops and validates the reverse transcriptase evolution platform and provides new tools, analysis methods, and datasets to study m1A biology.

Reverse transcriptase inhibitors in Aicardi-Goutières syndrome

Project description:Aicardi-Goutières syndrome (AGS) is a genetically heterogeneous encephalopathy whose pathology is linked to an abnormal type I interferon response induced by self-derived nucleic acids. Data indicate that endogenous retroelements represent one source of interferon-stimulatory self-nucleic acid. No effective therapies are available for this disorder. In this pilot study involving patients with AGS due to mutations in TREX1, RNASEH2A, RNASEH2B or SAMHD1 three nucleoside analogue reverse transcriptase inhibitors (RTIs) were administered over 12 months. Transcription profiling was done by RNA-seq.
