Dietary restriction extends longevity in organisms ranging from bacteria to mice and protects primates a variety of diseases, but the contribution each dietary component aging is poorly understood. Here we demonstrate that glucose specific amino acids promote stress sensitization through differential activation Ras/cAMP/PKA, PKH1/2 Tor/S6K pathways. Whereas sensitized cells Ras-dependent mechanism, threonine valine promoted cellular primarily by activating pathway serine via PDK1 orthologs...
Summary In mammals, extended periods of fasting leads to the accumulation blood ketone bodies including acetoacetate. Here we show that similar conversion leucine acetoacetate in starvation conditions induced body‐like acetic acid generation from S. cerevisiae . Whereas wild‐type and ras2Δ cells accumulated acid, long‐lived tor1Δ sch9Δ mutants rapidly depleted it through a mitochondrial acetate CoA transferase‐dependent mechanism, which was essential for lifespan extension. The sch9...
A clone (P2) coding for an allergen of Parietaria judaica (Pj) pollen has been isolated and sequenced from a cDNA library in lambda ZAP using pool 23 sera Pj‐allergic patients. The contained insert 622 nucleotides with open reading frame 133 amino acids (aa) putative signal peptide 31 aa giving deduced mature processed protein 102 molecular mass 11 344 Da. expressed recombinant protein, named rPar j 2.0101, was major since it reacted IgE 82% (23/28) the subjects analyzed. It shown to be new...
Abstract Par j 1.0101 is one of the two major allergens Parietaria judaica (Pj) pollen, and its three-dimensional structure was built by structural homology modeling. The resultant model used to identify putative IgE binding regions. Western blot analysis gene fragmentation products showed that 1 30 region capable specific from a pool sera (n = 30) patients allergic Pj pollen. Using as guide, deletion site-directed mutagenesis performed, amino acids involved in were identified. In addition,...
Background: The circulating tumor DNA (ctDNA) diagnostic accuracy for detecting phosphatidylinositol 4,5-bisphosphate 3-kinase catalytic subunit alpha ( PIK3CA) mutations in breast cancer (BC) is under discussion. We aimed to compare plasma and tissue PIK3CA alterations, encompassing factors that could affect the results. Methods: Two reviewers selected studies from different databases until December 2020. considered BC patients with matched ctDNA. performed meta-regression subgroup analyses...
