Project description:Paraffin-embedded lung and spleen tissues analyzed by Eksigent nanoLC-Ultra 2D System and QExactive mass spectrometer. Both lung and spleen tissues were extracted from animals at 4 different conditions (Not infected Ad libitum, Not infected Caloric restricted, Mycobacterium Tuberculosis (MTB) infected Ad libitum, Mycobacterium Tuberculosis (MTB) infected Caloric restricted). Globally, 24 and 23 runs are uploaded for lung and spleen tissues, respectively.
Project description:Aging is a key risk factor for disease in mammals, yet its molecular basis across organs remains unclear. Here, we performed bulk RNA sequencing on eight organs (brain, heart, kidney, liver, lung, skeletal muscle, spleen, testis) from male C57BL/6J mice at distinct life stages. Our analysis revealed that age-related transcriptomic shifts vary in timing and magnitude: early in lung, spleen, testis; mid-life in heart, kidney, skeletal muscle; and late in brain and liver. Magnitude ranged from very low (testis), low (brain, heart), moderate (lungs, skeletal muscle) to high (kidneys, liver, spleen). We uncovered organ-specific aging signatures, for instance, mitochondrial and epigenetic regulation in the kidney, metabolic/detoxification in the lung, and angiogenesis as well as ribosome biogenesis in the spleen). We also identified shared transcriptomic signatures, such as cellular senescence in the kidney and skeletal muscle, ECM remodeling in the heart, skeletal muscle and spleen), or inflammation in the heart, kidney, liver and lungs. These findings highlight unique and overlapping transcriptomic aging signatures, informing future therapeutic strategies to improve healthspan.
Project description:The importance of unanchored Ub in innate immunity has been shown only for a limited number of unanchored Ub-interactors. We investigated what additional cellular factors interact with unanchored Ub and whether unanchored Ub plays a broader role in innate immunity. To identify unanchored Ub-interacting factors from murine lungs, we used His-tagged recombinant poly-Ub chains as bait. These chains were mixed with lung tissue lysates and protein complexes were isolated with Ni-NTA beads. Sample elutions were subjected to mass spectrometry (LC-MSMS) analysis.
