The aim of the present study is to explore whether vasculogenic mimicry (VM) and bacterial L-form infection exist in human epithelial ovarian cancer (EOC) or not and to elucidate the correlation of L-form infection, expression of hypoxia inducible factor 1α (HIF-1α)/MMP-9 and VM. In 87 specimens of EOC and 20 specimens of ovarian benign epithelial tumor tissues, L-form infection was detected by Gram's staining, expression of HIF-1α/MMP-9 and VM were detected by immunohistochemical and histochemical staining. The results showed that the positive rates of HIF-1α and MMP-9 protein in EOC were 52.9% and 66.7%, while in benign epithelial tumor tissues, the positive rates were 10.0% and 10.0% respectively, and there were significant differences between them (P < 0.05). In EOC and benign epithelial tumor tissues, L-form infections ratios were 24.1% and 0, respectively, and the difference was also significant (P < 0.01). Expression of VM, HIF-1α and MMP-9 in EOC was significantly related to differentiation, abdominal implantation and lymph node metastasis and FIGO stage (P < 0.01). L-form infection had relationship with abdominal implantation, lymph node metastasis and FIGO stage . The expression of HIF-1α had positive relationship with expression of MMP-9 and VM (r = 0.505, 0.585, respectively, P < 0.01); there was also a positive relationship between MMP-9 expression and VM (r = 0.625, P < 0.01). Overexpression of VM, HIF-1α and MMP-9 were related to poor prognosis: the survival rates were significantly lower in positive patients than those in negative patients (P < 0.05). And the group with L-form infection also had poor prognosis: the survival rates were lower than those in group without infection (P < 0.05). FIGO stage, expression of VM, HIF-1α and MMP-9 were independent prognosis factors of EOC (P < 0.05). The results suggest that L-form infection, the expression of HIF-1α, MMP-9 and VM in EOC are related to differentiation, lymph node metastasis, clinical stage and prognosis. Combined detection of these indexes has an important role in predicting the progression and prognosis of EOC.
Am old enough to understand the difference between the Bay of Pigs - and roasting a pig at a epicurian feast. Been thru the hippy, yippie and yuppie years - always remaining who I am.
Very much believe in "Sing your own song - weave your own tapestry"
Am young enough to still know the thrill of new discoveries, the beauty of the evening, to celebrate the joy of another tommorow.
Survived these many decades with a severe medical problems. Sorting out the maze of now having two lymphomas and all their nasty little companions, but I continue.
Besides, being a simple iconoclastic eclectic, have been called many things. An incurable romanticist - with a strong touch of reality. Thinker, intellectual (God, how I hate that term) - been told I am a lion with the heart of the poet.
Know how to wage war and conquer my foes - but would rather be known as one who brings hope and life. To bring hope into anothers life is the ultimate of joys.
Life should be about bringing hope, peace, vision... a sense of purpose beyond yourself.
