Background Cancer cells that enter the metastatic cascade require traits that allow them to survive within the circulation and colonize distant organ sites. As disseminating cancer cells adapt to their changing microenvironments, they also modify their metabolism and metabolite production. Methods A mouse xenograft model of spontaneous tumor metastasis was used to determine the metabolic rewi...

The phthalocyanine dyes, Remazol Turquoise Blue G133, Everzol Turquoise Blue and Heligon Blue S4 are found to be biosorbed by Phanerochaete chrysosporium (white-rot fungi) and also metabolised by its ligninolytic extracellular enzymes resulting in dye decolourisation, formation of free copper ions and organic metabolites with ultimate extensive phthalocyanine ring breakdown. It is believed that...

Intracellular metabolites were evaluated during the continuous growth of Trichoderma harzianum P49P11 under carbon-limited conditions. Four different conditions in duplicate investigated (10 and 20 g/L glucose, 5.26/5.26 fructose/glucose 10 sucrose feed). Differences values some specific concentrations intracellular observed at steady-state for duplicates. The presence extracellular polysacchar...

Background Metabolomics, aiming at the quantification of all extracellular and intracellular metabolites, is a valuable tool for characterizing, understanding and manipulating the physiology of mammalian cells. While extracellular metabolite analysis is well established, required quenching and extraction procedures for intracellular metabolite analysis in mammalian suspension cells are not yet ...

results there were 39 cases with lymph node metastasis in 59 malignant tumors, and 0 cases in 6 benign follicular type tumors. the staining scores by jt-95 of the 39 tumors with lymph node metastasis were 5+ in eight cases and 6+ in 31 cases. on the other hand, the scores of 20 malignant tumors without lymph node metastasis were < 4+ in all of the cases. in the co-cultured assay, numerous adhes...

matrix metalloproteinases (mmps) are a family of neutral proteinases that are important in normal development, cellular differentiation or migration, angiogenesis, neurogenesis, wound repair, and a wide range of pathological processes such as oxidative stress and neuroinflammation. mmps have been demonstrated to increase the permeability of the blood–brain barrier (bbb) by degrading the compone...

BACKGROUND Saccharomyces cerevisiae var. boulardii is the only yeast species with probiotic properties. It is considered to have therapeutic significance in gastrointestinal disorders. In the present study, a comparative physiological study between this yeast and Saccharomyces cerevisiae (BY4742) was performed by evaluating two prominent traits of probiotic species, responses to different stres...

This study aimed to investigate the effect of potential metabolite(s) produced by Paraburkholderia spp. isolated from Rhizopogon roseolus (shouro mushroom) sporocarp on mycelial growth R. roseolus. For this purpose, we selected two molecularly identified bacteria: P. fungorum GIB024 and caledonica KN1. Direct confrontation assay at three different distances, a pour plate method that sampled bac...
