Mitochondrial transcription factor A is a proinflammatory mediator in hemorrhagic shock

Endogenous molecules released by dying cells [i.e., damage-associated molecular patterns (DAMPs)] after trauma and severe blood loss can activate pattern recognition receptors, leading to a cascade of inflammatory responses and organ injury. Mitochondrial transcription factor A (TFAM) is a transcription factor for mitochondrial DNA. TFAM is structurally related to high mobility group box 1 (HMG...

Heat shock factor 5 is essential for spermatogenesis in mice: Detected by a new monoclonal antibody

Objective(s): Here, we examined the function of our produced monoclonal antibody (mAb10C3) to recognize one of the most important members of the HEAT shock factor family, Hsf5, in embryonic development and in spermatogenic cells of adult mouse testis.Materials and Methods: The targeting effects of mAb10C3 were investigated by immunohisto...

Mediator as a general transcription factor.

Others have shown that yeast strains bearing a ts mutation in the Srb4 subunit of Mediator cease transcription of all mRNA at the restrictive temperature, in a manner virtually indistinguishable from a strain bearing a ts mutation in the largest subunit of RNA polymerase II. We find that srb4ts Mediator is defective for the stimulation of basal RNA polymerase II transcription at the restrictive...

Sphingosylphosphorylcholine is a proinflammatory mediator in cerebral arteries.

Inflammation has an important function in the development of cerebral vasospasm after subarachnoid hemorrhage (SAH); however, the mediators of this inflammatory response have not been clearly identified. In this study, we have investigated the potential function of two sphingolipids, which occur naturally in plasma and serum, sphingosylphosphorylcholine (SPC) and sphingosine 1-phosphate (S1P), ...
