OBJECTIVES:

Albumin messenger RNA (mRNA) expression is a marker of hepatocellular differentiation. Most published data are from review of tissue microarrays, and albumin in situ hybridization (ISH) expression across several tumor types is incompletely characterized.

Epizootic mortalities in American Crows (Corvus brachyrhynchos

Parathyroid adenomas are slow growing benign neoplasms associated with hypercalcemia, while atypical parathyroid adenomas and parathyroid carcinomas are uncommon tumors and their histologic features may overlap with parathyroid adenomas. LncRNAs participate in transcription and in epigenetic or post-transcriptional regulation of gene expression, and probably contribute to carcinogenesis.

Cholinergic interneurons (CINs) are critical regulators of striatal network activity and output. Changes in CIN activity are thought to encode salient changes in the environment and stimulus-response-outcome associations.

Activity-dependent myelination is thought to contribute to adaptive neurological function. However, the mechanisms by which activity regulates myelination and the extent to which myelin plasticity contributes to non-motor cognitive functions remain incompletely understood. Using a mouse model of chemotherapy-related cognitive impairment (CRCI), we recently demonstrated that methotrexate (MTX) chemotherapy induces complex glial dysfunction for which microglial activation is central.

While it is now appreciated that certain long noncoding RNAs (lncRNAs) have important functions in cell biology, relatively few have been shown to regulate development in vivo, particularly with genetic strategies that establish cis versus trans mechanisms. Pnky is a nuclear-enriched lncRNA that is transcribed divergently from the neighboring proneural transcription factor Pou3f2.

Current human papillomavirus (HPV) detection methods in oropharyngeal squamous cell carcinoma (OPSCC) have varying sensitivity and specificity. We aimed to compare different HPV-detection methods against the test used in clinical practice, ie, p16 immunohistochemistry (IHC) and to evaluate whether another HPV-detection test additional to p16 IHC would be worthwhile in OPSCC specimens.

Ca2+ coordinates diverse cellular processes, yet how function-specific signals arise is enigmatic.

Sparse populations of neurons in the dentate gyrus (DG) of the hippocampus are causally implicated in the encoding of contextual fear memories. However, engram-specific molecular mechanisms underlying memory consolidation remain largely unknown.

Hutchinson-Gilford progeria syndrome (HGPS) is the result of a defective form of the lamin A protein called progerin. While progerin is known to disrupt the properties of the nuclear lamina, the underlying mechanisms responsible for the pathophysiology of HGPS remain less clear.
