Abstract
Polyamines are polycationic molecules which contains two or more amino groups (-NH3+) highly charged at physiological pH, and among them we found spermine, spermidine, putrescine, and cadaverine. They interact with proteins, nucleic acids, modulate Ca2+, K+, and Na+ channels, and protect sperm from oxidative stress. In this work, we evaluate the effect of spermine, spermidine, and putrescine on the total, progressive and kinematic parameters of motility, capacitation, acrosome reaction, also in presence and absence of the dbcAMP, an analogue of the cAMP, and the IBMX, a phosphodiesterase inhibitor. In addition, we evaluated the intracellular concentrations of cAMP [cAMP]i, and performed an in silico analysis between polyamines and the sAC from mouse to predict the possible interaction among them. Our results showed that all polyamines decrease drastically the total, progressive and the kinetic parameters of sperm motility, decrease the capacitation, and only spermidine and putrescine impeded the acquisition of acrosome reaction. Moreover, the effect of polyamines was attenuated but not countered by the addition of db-cAMP and IBMX, suggesting a possible inhibition of the sAC. Also, the presence of polyamines induced a decrease of the [cAMP]i, and the in silico analysis predicted a strong interaction among polyamines and the sAC. Overall, the evidence suggests that probably the polyamines interact and inhibit the activity of the sAC.

Cl- is required for HCO3- entry necessary for sperm capacitation in guinea pig: involvement of a Cl-/HCO3- exchanger (SLC26A3) and CFTR. Biol Reprod 2008; 80:115-23.

Abstract
Our previous study demonstrated the involvement of cystic fibrosis transmembrane conductance regulator (CFTR) in transporting bicarbonate that is necessary for sperm capacitation; however, whether its involvement is direct or indirect remains unclear. The present study investigated the possibility of a Cl-/HCO3- exchanger (solute carrier family 26, number 3 [SLC26A3]) operating with CFTR during guinea pig sperm capacitation. Incubating sperm in media with various concentrations of Cl- resulted in varied percentages of capacitated sperm in a concentration-dependent manner. Depletion of Cl-, even in the presence of HCO3-, abolished sperm capacitation and vice versa, indicating the involvement of both anions in the process. Capacitation-associated HCO3--dependent events, including increased intracellular pH, cAMP production, and protein tyrosine phosphorylation, also depend on Cl- concentrations. Similar Cl- dependence and inhibitor sensitivity were observed for sperm-hyperactivated motility and for sperm-egg fusion. The expression and localization of CFTR and SLC26A3 were demonstrated using immunostaining and Western blot analysis. Taken together, our results indicate that Cl- is required for the entry of HCO3- that is necessary for sperm capacitation, implicating the involvement of SLC26A3 in transporting HCO3-, with CFTR providing the recycling pathway for Cl-.

Abstract
Mammalian sperm do not respond to inducers of the acrosome reaction immediately after ejaculation. They become responsive after they are removed from seminal plasma and incubated in an appropriate medium. We tested the effects of seminal plasma on the development of acrosomal responsiveness. Washed human sperm incubated 24 hr in vitro with 10% (v/v) seminal plasma did not complete an acrosome reaction when exposed to human follicular fluid, progesterone, or ionomycin. Seminal plasma did not reduce sperm viability or motility. Electron microscopy of sperm incubated 24 hr with 5% seminal plasma and then treated with progesterone revealed no sign of membrane fusion or other changes that are associated with the acrosome reaction. During a 12-hr incubation, seminal plasma was 50% effective at inhibiting the acrosomal response to progesterone when diluted 821 +/- 112 fold (mean +/- SD, n = 3). Sperm that were incubated with seminal plasma for 24 hr and then washed free of the seminal plasma became acrosomally responsive over the following 24 hr, at a rate similar to that of sperm not incubated with seminal plasma in vitro. When sperm were incubated 6 hr without seminal plasma and then seminal plasma was added, the sperm population transiently became more responsive to progesterone, and then became unresponsive. During incubation in vitro, the ability of sperm to have an augmented response to a mixture of seminal plasma plus progesterone developed slightly earlier and more rapidly than ability to respond to progesterone alone. When sperm were incubated 24 hr without seminal plasma, a few acrosome reacted in response to the addition of seminal plasma alone.(ABSTRACT TRUNCATED AT 250 WORDS)
