A New Paradigm: 46 Structural Cell Types Function as Environment‐Supporting Innate Immune Cells, With Endothelial and Vascular Smooth Muscle Cells as Key Prototypes

iNew Medicine, EarlyView.
ABSTRACT The scope, organization, and biological significance of innate immune functions across structural cell types remain poorly defined. To address these fundamental knowledge gaps, we analyzed experimental data of transcriptomes generated by our group and others.

Kinesin-5 Eg5 is essential for spindle assembly and chromosome alignment of mouse spermatocytes

Cell Division, 2020
Background Microtubule organization is essential for bipolar spindle assembly and chromosome segregation, which contribute to genome stability. Kinesin-5 Eg5 is known to be a crucial regulator in centrosome separation and spindle assembly in mammalian ...

Multiple Roles of Protamine Kinase SRPK1 and Phosphatase PP1γ in Sperm Development

PROTEOMICS, EarlyView.
ABSTRACT Protein phosphorylation regulates key events of male germ cell differentiation. In the testis, SRPK1 and PP1γ are involved in protamine phosphorylation and dephosphorylation, respectively, and their deregulation is linked to defective chromatin structure and male infertility.

Male Hybrid Sterility in the Mule Duck is Associated with Meiotic Arrest in Primary Spermatocytes

The Journal of Poultry Science, 2013
Hybrid sterility is a postzygotic reproductive isolation mechanism that prevents successful interbreeding between different species. The mule duck, an intergeneric F1 hybrid between the domestic duck (Anas platyrhynchos) and Muscovy duck (Cairina ...

Synergistic Toxicity of Low‐Concentration Metal Mixture on Male Rats: Reproductive, Renal, and Hepatic Effects

Environmental Toxicology, EarlyView.
ABSTRACT Mining plays a crucial role in economic development, but improper management can lead to severe environmental degradation. Particularly for iron ore, mining generates vast amounts of tailings often stored in unstable dams. This study aims to investigate the toxicological impacts of environmentally relevant concentrations of metals mixture ...

Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

Andrology, EarlyView.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.

MOF influences meiotic expansion of H2AX phosphorylation and spermatogenesis in mice.

PLoS Genetics, 2018
Three waves of H2AX phosphorylation (γH2AX) have been observed in male meiotic prophase I: the first is ATM-dependent and occurs at leptonema, while the second and third are ATR-dependent, occuring at zygonema and pachynema, respectively.
