Triosephosphate isomerase (TPI) deficiency is a poorly understood disease characterized by hemolytic anemia, cardiomyopathy, neurologic dysfunction, and early death. TPI deficiency is one of a group of diseases known as glycolytic enzymopathies, but is unique for its severe patient neuropathology and early mortality. The disease is caused by missense mutations and dysfunction in the glycolytic ...

A thiol protease inhibitor (TPI) was found in culture media of human malignant melanoma cells (Bowes) at 1.5 to 2.3 units/day/flask (full sheet, 75 sq cm). This amount well exceeded that for cultured nonmalignant cells (human fetal lung fibroblasts). In the intracellular region of the melanoma cells, TPI activity was localized mainly in the cytosol fraction. The difference in specific activitie...

Evidence for the in planta defensive function of trypsin protease inhibitors (TPIs) comes from observations of enhanced herbivore resistance after heterologous TPI expression or the manipulation of signal cascades that activate numerous defense responses, including TPI production; no studies have altered the expression of an endogenous pi gene to examine defensive function. We isolated two gene...

Tailored patient information (TPI) systems are computer programs which produce persoualised heath-information material for patients. TPI systems are of growing interest to the natural-language generation (NLG) community; many TPI systems have also been developed in the medical community, usually with mail-merge technology. No matter what technology is used, experience shows that it is not easy ...

The glycolytic enzyme triosephosphate isomerase (TPI; EC 5.3.1.1) of Staphylococcus aureus is a candidate adhesion molecule for the interaction between the bacterium and the fungal pathogen Cryptococcus neoformans. TPI may recognize the mannan backbone of glucuronoxylomannan (GXM) of C. neoformans. We purified TPI from extracts of S. aureus surface proteins to investigate its binding by surface...

ABSTRACT Triosephosphate isomerase (TPI) catalyzes the interconversion of dihydroxyacetone phosphate (DHAP) and glyceraldehyde-3-phosphate (G3P). This reaction is required for glycolysis and gluconeogenesis, and tpi has been predicted to be essential for growth of Mycobacterium tuberculosis. However, when studying a conditionally regulated tpi knockdown mutant, we noticed that depletion of TPI ...

BACKGROUND AND PURPOSE This study aimed to test the explanatory qualities of the Stroke-Thrombolytic Predictive Instrument (S-TPI) when applied to patients treated in routine practice. METHODS S-TPI predictions were compared with observed outcomes in terms of normal/near-normal (modified Rankin Scale score, ≤1) and catastrophic outcome (modified Rankin Scale score, ≥5) at 3 months. Logistic r...

The inhibition of triosephosphate isomerase (TPI) in glycolysis by the pyruvate kinase (PK) substrate phosphoenolpyruvate (PEP) results in a newly discovered feedback loop that counters oxidative stress in cancer and actively respiring cells. The mechanism underlying this inhibition is illuminated by the co-crystal structure of TPI with bound PEP at 1.6 Å resolution, and by mutational studies g...

The complete gene encoding Schistosoma mansoni triosephosphate isomerase (TPI) was isolated from a lambda phage genomic library on 2 overlapping clones. These genomic clones have been characterized by restriction mapping and DNA sequencing of the 5' flanking region, the exons, the intron boundaries and the polyadenylation addition site. S. mansoni TPI is encoded by 6 exons spanning a region of ...

TPI deficiency glycolytic enzymopathy is a progressive neurodegenerative condition that remains poorly understood. The disease is caused exclusively by specific missense mutations affecting the triose phosphate isomerase protein (TPI) and clinically features hemolytic anemia, adult-onset neurological impairment, degeneration, and reduced longevity. TPI has a well-characterized role in glycolysi...
