Abstract: Premature infants (PIs) are at risk of suffering necrotizing enterocolitis (NEC), and infants consuming human milk (HM) show a lower incidence than infants receiving formula. The composition of HM has been studied in depth, but the lipid content of HM-derived small extracellular vesicles

Abstract: The nuclear mitochondrial DNA (NUMT) is found in cancer cells, but the mitochondrial DNAs entering the nuclei in normal cells have not been captured. Here, we utilized super-resolution optical imaging to capture the phenomenon by the probe PicoGreen and found mitochondrial DNAs and mitochondria accumulated in the nucleoli by four probes and overexpressing the MRPL58-DsRed.

J., Wei, Y., Chapman, H. A., Le Saux, C. J. Abstract: Reciprocal interactions between alveolar fibroblasts and epithelial cells are crucial for lung homeostasis, injury repair, and fibrogenesis, but underlying mechanisms remain unclear. To investigate this, we administered the fibroblast-selective TGF{beta}1

A., Gygi, S., Kellogg, D. Abstract: Cell growth is required for cell cycle progression. The amount of growth required for cell cycle progression is reduced in poor nutrients, which leads to a reduction in cell size. In budding yeast, nutrients influence cell size by modulating the duration and extent of

Abstract: Epithelia must be able to resist mechanical force to preserve tissue integrity. While intercellular junctions are known to be important for the mechanical resistance of epithelia, the roles of tight junctions (TJs) remain to be established. We previously demonstrated that epithelial cells devoid of the

Abstract: A core pathophysiologic feature underlying many respiratory diseases is multiciliated cell dysfunction, leading to inadequate mucociliary clearance. Due to the prevalence and highly variable etiology of mucociliary dysfunction in respiratory diseases, it is critical to understand the mechanisms controlling

Abstract: Stimulated emission depletion microscopy (STED) is a powerful tool for studying nanoscale cell structure and activity, but the difficulties it encounters in multicolor imaging limit its application in biological research. To overcome the disadvantages of limited number of channels and high cost of

Abstract: We have previously identified the novel splicing variant of mouse Ppar{gamma} (Ppar{gamma}1sv) and proposed the synergistic regulation of the early stage of adipocyte differentiation by Ppar{gamma}1sv and Ppar{gamma}2. Here, we report the finding of PPAR{gamma}-binding sites within the Ppar{gamma} gene locus and its importance in adipogenesis and propose

Abstract: Mitochondria are not only essential for energy production in eukaryocytes but also a key regulator of intracellular signaling. Here, we report an unappreciated role of mitochondria in regulating cytosolic protein translation in skeletal muscle cells (myofibers). We show that the expression of mitochondrial protein FAM210A

Abstract: An emerging approach to studying major mental illness is through proteostasis, with the identification of several proteins that form insoluble aggregates in the brains of patients. One of these is Disrupted in Schizophrenia 1 (DISC1), a neurodevelopmentally-important scaffold protein, and the product of a classic schizophrenia risk gene. DISC1 was seen to

Abstract: Rapid recovery of proteasome activity may contribute to intrinsic and acquired resistance to FDA-approved proteasome inhibitors. Previous studies have demonstrated that the expression of proteasome genes in cells treated with sub-lethal concentrations of proteasome inhibitors is upregulated by the transcription factor Nrf1 (NFE2L1), which is activated by a novel

Abstract: Lysosomes have long been known for their acidic lumen and efficient degradation of cellular byproducts. In recent years it has become clear that their function is far more sophisticated, involving multiple cell signaling pathways and interactions with other organelles. Unfortunately, their acidic interior, fast dynamics, and small

Abstract: The PAR polarity network is a paradigmatic example of how systems of mutually antagonism interactions among peripheral membrane binding proteins allow them to form and maintain complementary polar domains in response to a transient polarizing cue. The oligomeric scaffolding protein PAR-3 has emerged as a keystone member of the PAR network in many different

Abstract: Protein-bound ceramides, specialized ceramides covalently bound to corneocyte surface proteins, are essential for skin permeability barrier function. However, their exact structure and target amino acid residues are unknown. Here, we found that epoxy-enone (EE) ceramides, precursors of protein-bound ceramides, as

Abstract: X-ray tomography and x-ray fluorescence imaging are two non-invasive imaging techniques to study cellular structures and chemical element distributions, respectively. However, correlative X-ray tomography and fluorescence imaging for the same cell has yet to be routinely realized due to

Abstract: Cells arrest growth and enter a quiescent state upon nutrient deprivation. However, the molecular processes by which cells respond to different starvation signals to regulate exit from the cell division cycle and initiation of quiescence remains poorly understood. To study the role of protein expression and signaling in quiescence we combined temporal
