Identification of a Novel Human E-Cadherin Splice Variant and Assessment of Its Effects Upon EMT-Related Events.

Epithelial Cadherin (E-cadherin) is involved in calcium-dependent cell-cell adhesion and signal transduction. The E-cadherin decrease/loss is a hallmark of Epithelial to Mesenchymal Transition (EMT), a key event in tumor progression. The underlying molecular mechanisms that trigger E-cadherin loss and consequent EMT have not been completely elucidated.

The acrosome reaction response assay: a new way to identify patients in whom pentoxifylline would improve the human follicular fluid-induced acrosome reaction.

The effect of pentoxifylline on the spontaneous and follicular fluid (hFF)-induced acrosome reaction (AR) was studied in an attempt to identify those patients who would benefit from the use of pentoxifylline as an AR-stimulating agent. Pentoxifylline (1 mg/ml) produced no significant increase over spontaneous AR at any of the time points studied (60 min: 6.2% +/- 2.
