Recently, the myelin proteolipid protein gene () was shown to be expressed in the glia of the enteric nervous system (ENS) in mouse. However, beyond this, not much is known about its expression in the intestine. To address this matter, we investigated expression at the mRNA and protein levels in the intestine of mice at different ages (postnatal days 2, 9, 21, and 88).

Much of what is known about the mechanisms that control the developmental expression of the myelin proteolipid protein gene () has been attained through use of transgenic animal models. In this study, we analyzed expression of related transgenes which utilize genomic DNA from either human or mouse to drive expression of a reporter. Human () sequence span either the proximal 6.

Fetal alcohol spectrum disorders (FASD) are alarmingly common and result in significant personal and societal loss. Neuropathology of the hippocampus is common in FASD leading to aberrant cognitive function. In the current study, we evaluated the effects of ethanol on the expression of a targeted set of molecules involved in neuroinflammation, myelination, neurotransmission, and neuron function in the developing hippocampus in a postnatal model of FASD.

Article Synopsis
  • - The PLP1 gene is crucial for producing the main protein in the brain's myelin, and its expression is tightly controlled due to its link to neurological disorders when imbalanced.
  • - A recent study explored how certain regions in the PLP1 gene affect its expression in transgenic mice, specifically focusing on the wmN1 and ASE regions found in intron 1.
  • - Findings revealed that the wmN1 region is essential for gene expression in various cell types, while removing the ASE region did not impact expression, suggesting compensatory factors might be at play.

Xq22 deletions that encompass PLP1 (Xq22-PLP1-DEL) are notable for variable expressivity of neurological disease traits in females ranging from a mild late-onset form of spastic paraplegia type 2 (MIM# 312920), sometimes associated with skewed X-inactivation, to an early-onset neurological disease trait (EONDT) of severe developmental delay, intellectual disability, and behavioral abnormalities. Size and gene content of Xq22-PLP1-DEL vary and were proposed as potential molecular etiologies underlying variable expressivity in carrier females where two smallest regions of overlap (SROs) were suggested to influence disease. We ascertained a cohort of eight unrelated patients harboring Xq22-PLP1-DEL and performed high-density array comparative genomic hybridization and breakpoint-junction sequencing.
