Testicular germ cell tumors (TGCT) originate from germ cells. The 129-Ter and M19 (129.MOLF-Chr19 consomic) mouse strains have extremely high incidences of TGCTs. We found that the expression levels of Sf1-encoded splicing factor 1 (SF1) can modulate the incidence of

Astrocytes are essential mediators of many aspects of synaptic transmission and neuroplasticity. Exercise has been demonstrated to induce neuroplasticity and synaptic remodeling, such as through mediating neurorehabilitation in animal models of neurodegeneration. However, the effects of exercise on astrocytic function

Osteoarthritis (OA), the most common aging-related joint disease, is caused by an imbalance between extracellular matrix synthesis and degradation. Here, we discover that both strands of microRNA-455 (miR-455), -5p and -3p, are up-regulated by Sox9, an essential transcription factor for

Following CNS injury, astrocytes become "reactive" and exhibit pro-regenerative or harmful properties. However, the molecular mechanisms that cause astrocytes to adopt either phenotype are not well understood. Transglutaminase 2 (TG2) plays a key role in regulating the response of astrocytes

PeerJ, 9, e11545-e11545 (2021-06-19)
The CCT complex is an important mediator of microtubule assembly and intracellular protein folding. Owing to its high expression in spermatids, CCT knockdown can disrupt spermatogenesis. In the present report, we therefore evaluated the in vivo functionality of the testis-specific

Fibrosis due to extracellular matrix (ECM) secretion from myofibroblasts complicates many chronic liver diseases causing scarring and organ failure. Integrin-dependent interaction with scar ECM promotes pro-fibrotic features. However, the pathological intracellular mechanism in liver myofibroblasts is not completely understood, and

SOX9 encodes a transcription factor that governs cell fate specification throughout development and tissue homeostasis. Elevated SOX9 is implicated in the genesis and progression of human tumors by increasing cell proliferation and epithelial-mesenchymal transition. We found that in response to
Kathleen M Capaccione et al.
Oncotarget, 5(11), 3636-3650 (2014-07-09)
Sox9 has gained increasing importance both functionally and as a prognostic factor in cancer. We demonstrate a functional role for Sox9 in inducing a mesenchymal phenotype in lung ADC. We show that Sox9 mRNA and protein are overexpressed in lung

Development (Cambridge, England), 142(8), 1458-1469 (2015-03-21)
Epigenetic mechanisms involved in the establishment of lung epithelial cell lineage identities during development are largely unknown. Here, we explored the role of the histone methyltransferase Ezh2 during lung lineage determination. Loss of Ezh2 in the lung epithelium leads to

Testicular Leydig cells (LCs) are the primary source of circulating androgen in men. As men age, circulating androgen levels decline. However, whether reduced LC steroidogenesis results from specific effects of aging within LCs or reflects degenerative alterations to the wider

Advances in three-dimensional culture technologies have led to progression in systems used to model the gonadal microenvironment in vitro. Despite demonstrating basic functionality, tissue organisation is often limited. We have previously detailed a three-dimensional culture model termed the three-layer gradient

The mammalian urogenital system derives from multipotent progenitor cells of different germinal tissues. The contribution of individual sub-populations to specific components of the mature system, and the spatiotemporal restriction of the respective lineages have remained poorly characterized. Here, we use

Testes of seasonally breeding species experience a severe functional regression before the non-breeding period, which implies a substantial mass reduction due to massive germ-cell depletion. Two alternative mechanisms of seasonal germ-cell depletion have been described in mammals, apoptosis and desquamation
