Mammalian ejaculated spermatozoa must undergo a series of changes in the female reproductive tract, collectively called capacitation, in order to fertilize the oocyte. We reported that fibronectin (Fn), a glycoprotein from the extracellular matrix, a

One of the first events of mammalian sperm capacitation is the activation of the soluble adenyl cyclase/cAMP/protein kinase A (SACY/cAMP/PKA) pathway. Here, we evaluated whether the increase in PKA activity at the onset of human sperm capacitation is

During the passage of sperm through the oviduct, spermatozoa bind to the oviductal epithelium and form the oviductal reservoir. This interaction keeps the fertilizing capacity of sperm until ovulation-associated signals induce sperm release from the

Summary In human spermatozoa, protein kinases have a role in the acrosome reaction (AR) induced by a variety of stimuli. However, there is disagreement or a lack of information regarding the role of protein kinases and phosphatases in the progesteron

The aim of this work was to determine whether laminin (Ln), an extracellular matrix protein, induces the intracellular events that may be involved in producing the acrosome reaction in human sperm. To this end, we evaluated the effect of Ln on tyrosi

The proteasome is a multicatalytic cellular complex present in human sperm that plays a significant role during several steps of mammalian fertilization. Here, we present evidence that the proteasome is involved in human sperm capacitation. Aliquots

Background Previously we showed that the human sperm proteasome plays significant roles during mammalian fertilization. Here we studied the effect of fibronectin (Fn), an extracellular matrix protein present in the cumulus oophorus of the oocyte, on

We have previously shown that type IV collagen (α1 (IV) and α2 (IV) collagen chains) (Col-IV) inhibits testosterone (T) production by Leydig cells (LC). The aim of this study was to analyze mechanism/s by which Col-IV exerts this effect. No signifi

Galectin-1 (Gal-1), a beta galactoside-binding lectin, is involved in multiple biological functions, such as cell adhesion, apoptosis, and metastasis. On the basis of its ability to interact with extracellular matrix (ECM) glycoproteins, we investiga

There are few reports on the role of protein phosphatases during capacitation. Here, we report on the role of PP2B, PP1, and PP2A during human sperm capacitation. Motile sperm were resuspended in non-capacitating medium (NCM, Tyrode's medium, albumin
