Elevated expression of matrix metalloproteinase-9 is associated with bladder cancer pathogenesis.

Objective: This study investigated the association between abnormal matrix metalloproteinase-9 (MMP-9) expression and bladder cancer (BC) development.

Materials And Methods: In a retrospective analysis, this study used tissue samples derived from 92 patients pathologically diagnosed with BC (experimental group), who were hospitalized between September 2012 and June 2014 at the Urinary Surgery of Department of Urology, Lanzhou University Second Hospital. As controls (control group), 63 normal pericancerous bladder mucosal tissues (3 cm distant form edge of BC foci) with confirmed pathology were selected from the same time period.

Correlations of Foxo3 and Foxo4 expressions with clinicopathological features and prognosis of bladder cancer.

Objective: The study is performed to explore the correlations of forkhead box O3 (FoxO3) and forkhead box O4 (FoxO4) expressions with clinicopathological features and prognosis of bladder cancer.

Methods: Bladder cancer tissues and adjacent normal tissues from the recruited 222 patients were collected. Quantitative real-time polymerase chain reaction (qRT-PCR), Western blotting and immunohistochemistry were applied to determine the expressions of FoxO3 and FoxO4.

Downregulation of VEGFA inhibits proliferation, promotes apoptosis, and suppresses migration and invasion of renal clear cell carcinoma.

Objective: The aim of this study was to investigate the effects of vascular endothelial growth factor A (VEGFA) on cell proliferation, apoptosis, migration, and invasion in renal clear cell carcinoma (RCCC).

Methods: Between June 2012 and June 2015, RCCC tissues were obtained for the experimental group, and RCCC adjacent tumor-free kidney parenchyma tissues were obtained for the control group. VEGFA mRNA and protein expressions and phosphoinositide 3-kinase, serine/threonine-specific protein kinase (AKT), and phosphorylated-AKT protein expressions were detected.

Elevated matrix metalloproteinase-9 expression may contribute to the pathogenesis of bladder cancer.

The present study investigated the potential association between matrix metalloproteinase-9 (MMP-9) expression and the pathogenesis of bladder cancer. The present study reviewed previous studies published in Chinese and English using predefined selection criteria, which identified high-quality studies concerning MMP-9 and bladder cancer. Statistical analyses of the data were conducted using Comprehensive Meta-Analysis software version 2.

Genes expression analyses of sea-island cotton (Gossypium barbadense L.) during fiber development.

Sea-island cotton (Gossypium barbadense L.) is one of the most valuable cotton species due to its silkiness, luster, long staples, and high strength, but its fiber development mechanism has not been surveyed comprehensively. We constructed a normalized fiber cDNA library (from -2 to 25 dpa) of G.
