Does intravesical Escherichia coli lipopolysaccharide stimulate an increase in bladder nerve growth factor?
E. coli LPS can stimulate increased NGF message and protein in the bladder. The increase in NGF protein preceded the increase in mRNA, suggesting that this increase was not the result of gene transcription. It is possible that NGF participates in the pathogenesis of pain associated with bacterial cystitis.
The presence of atypia and mitosis across a uterine serous carcinoma is notoriously variable in magnitude and extent, potentially making evaluation of these features difficult and subsequent grading subjective. Our findings thus show that actual prognostic utility of application of MDACC two-tier grading system to uterine serous carcinoma may not be applicable.
