Hyaluronic acid is a major component of extracellular matrix which plays an important role in development, cellular response to injury and inflammation, cell migration, and cancer. The naked mole-rat (Heterocephalus glaber) contains abundant high-molecular-mass hyaluronic acid in its tissues, which co...
lactis Lc4. Such an effect was noted when applying the Lc4-derived CFS on two CRC cell lines - HCT116 and HT-29. We aimed to identify the main native molecule(s) responsible for this effect and to elucidate its mechanism of action. Materials and methods...
Gut microorganisms are solely responsible for the reduction of bilirubin to urobilinogen, potentially using the molecule as a terminal electron acceptor in anaerobic respiration. Despite the recognized role of gut microorganisms in bilirubin reduction, the gut microbial enzyme that reduces bilirubin to ur...
To summarize, each portion of the parent molecule seemed to play an important role, only the modification of salicylate fragment being tolerated. Figure 7 The effect of promysalin and the derivative analogs on S. thermophilus DSM 20617 T cell membrane integrity and cell viability. Flow ...
Creatine, an amino acid, which is located in the body’s muscles and the brain, is made of seafood and red meat. On the other hand, creatine supplement is made by combining cyanamide and sarcosine, which are vegan in nature. Does creatine come from plants? No, creatine is not present ...
The expression of the mutant alpha globin protein was observed in immunoprecipitate from lysed RBCs, in which an approximate 400 Da peak shift (corresponding to the loss of four amino acids from the polypeptide chain) was observed in a matrix-assisted laser desorption ionization mass spectrometer...
It is thus possible that these represent a contact site responsible for the transfer of lipids between the organelles. In S. cerevisiae it was also reported that an intimate physical contact is created as peroxisomes stably adhere to LDs when cells are grown in oleic acid (where peroxisomes ...
