The Creb-Regulated Transcriptional Coactivator (Crtc) family of transcriptional coregulators drive Creb1-mediated transcription effects on metabolism in many tissues, but the in vivo effects of Crtc2/Creb1 transcription on skeletal muscle metabolism are not known. Skeletal muscle-specific overexpression of Crtc2 (Crtc2 mice) induced greater mitochondrial activity, metabolic flux capacity for both carbohydrates and fats, improved glucose tolerance and insulin sensitivity, and increased oxidative capacity, supported by upregulation of key metabolic genes. Crtc2 overexpression led to greater weight loss during alternate day fasting (ADF), selective loss of fat rather than lean mass, maintenance of higher energy expenditure during the fast and reduced binge-eating …

In 2020, the global prevalence of human immunodeficiency virus (HIV) infection was estimated to be 38 million, and a total of 690,000 people died from acquired immunodeficiency syndrome (AIDS)–related complications. Notably, around 12.6 million people living with HIIV/AIDS did not have access to life-saving treatment. The advent of the highly active antiretroviral therapy (HAART) in the mid-1990s remarkably enhanced the life expectancy of people living with HIV/AIDS as a result of improved immune functions. However, HAART has several drawbacks, especially when it is not used properly, including a high risk for the development of drug resistance, as well as undesirable …

Development Of A Method Using Retrograde Neuronal Tracers To Neuroanatomically Characterize Respiratory Neural Circuitry, Samantha Thomas, Angelo Lepore

Phase 1

Introduction:

Loss of respiratory function is one of the leading causes of death following spinal cord injury (SCI). Existing studies have demonstrated that pre-phrenic interneurons (PPIN’s) can be recruited into the phrenic motor neuron (PhMN) pathway following cervical SCI and may contribute to respiratory recovery, but there is still a lack of information detailing the nature of these changes and the extent they may improve diaphragm function. This project aims to validate a method of utilizing neuronal tracers to further characterize the intact respiratory circuitry.

Methods:

This study was carried out using a rat model. A fluorophore-conjugated retrograde neuronal …
