The Sperm-Associated Antigen 11A (Spag11a) Knockout Mice Display Sub-Fertility and Perturbations in the Sperm Proteome.

Spermatogenesis and sperm maturation that occur in the testis and epididymis respectively are crucial for fertility. Factors secreted by the testicular and epididymal epithelial cells govern the processes of gametogenesis and maturation. Proteins encoded by the sperm-associated antigen 11a (Spag11a) gene are implicated as having a possible role in sperm maturation.

Effect of Spag11a gene knockout on the epididymis in mice: A histopathological and molecular analyses.

The sperm-associated antigen 11a (Spag11a) gene is exclusively expressed in the caput epididymis. Our previous studies demonstrated that small interfering RNA (siRNA)-mediated ablation of this gene resulted in increased proliferation of epididymal epithelial cells. Further, active immunization-mediated ablation of SPAG11A protein increased the susceptibility of male reproductive tract tissues to diethylnitrosamine (DEN)-induced tumorigenesis.

Uroplakin 1a Interacts with Regucalcin and Proteasome Subunit Beta 1.

Uroplakins (UPKs) are specialized proteins that plan an important role in protecting the epithelium of the bladder from toxic waste. We recently demonstrated the expression pattern of UPKs in the male reproductive tract and their importance in sperm function in murine models. However, the exact mechanisms through which UPKs affect spermatogenesis are not reported.

Characterization of SPINK2, SPACA7 and PDCL2: Effect of immunization on fecundity, sperm function and testicular transcriptome.

Testicular factors play a vital role in spermatogenesis. We characterized the functional role of rat Spink2, Spaca7 and Pdcl2 genes. Their primary, secondary and tertiary structure were deduced in silico.

Lytic Bacteriophages Against Bacterial Biofilms Formed by Multidrug-Resistant , , , and Isolated from Burn Wounds.

Use of bacteriophages as antibiofilm agents to tackle multidrug-resistant bacteria has gained importance in recent years. In this study, biofilm formation by , , , and under different growth conditions was studied. Furthermore, the ability of bacteriophages to inhibit biofilm formation was analyzed.
