Alternative splicing is an FXRα loss-of-function mechanism and impacts energy metabolism in hepatocarcinoma cells.

Farnesoid X receptor α (FXRα, NR1H4) is a bile acid-activated nuclear receptor that regulates the expression of glycolytic and lipogenic target genes by interacting with the 9-cis-retinoic acid receptor α (RXRα, NR2B1). Along with cofactors, the FXRα proteins reported thus far in humans and rodents have been observed to regulate both isoform (α1-4)- and tissue-specific gene expression profiles to integrate energy balance and metabolism. Here, we studied the biological functions of an FXRα naturally occurring spliced exon 5 isoform (FXRαse5) lacking the second zinc-binding module of the DNA-binding domain.

Understanding the role of endocrine disrupting chemicals in testicular germ cell cancer: Insights into molecular mechanisms.

This comprehensive review examines the complex interplay between endocrine disrupting chemicals (EDCs) and the development of testicular germ cell tumors (TGCTs). Despite the high cure rates of TGCTs, challenges in diagnosis and treatment remain, necessitating a deeper understanding of the etiology of the disease. Here, we emphasize current knowledge on the role of EDCs as potential risk factors for TGCTs, focusing on pesticides and perfluorinated and polyfluoroalkyl substances (PFAs/PFCs).

Identification of the Role of TGR5 in the Regulation of Leydig Cell Homeostasis.

Understanding the regulation of the testicular endocrine function leading to testosterone production is a major objective as the alteration of endocrine function is associated with the development of many diseases such as infertility. In the last decades, it has been demonstrated that several endogenous molecules regulate the steroidogenic pathway. Among them, bile acids have recently emerged as local regulators of testicular physiology and particularly endocrine function.

Dementia Care at the End of Life: A Clinically Focused Review.

With the geriatric population in the United States growing rapidly, the prevalence of dementia is expected to rise concomitantly. As dementia is an invariably progressive and terminal illness, planning for and managing end of life care in dementia is an important part of the overall process of dementia care. Unfortunately, this is often neglected outside of formal palliative and hospice medicine training programs and geriatric psychiatrists are left without preparation on how to manage, as well as counsel patients and families on, this important phase of dementia care.
