Protein kinase A (PKA) activity is pivotal for proper functioning of the human heart, and its dysregulation has been implicated in a variety of cardiac pathologies. PKA regulatory subunit 1α (R1α, encoded by the PRKAR1A gene) is highly expressed in the heart, and controls PKA kinase activity by sequestering PKA catalytic subunits. Patients with PRKAR1A mutations are often diagnosed with Carney complex (CNC) in early adulthood, and may die later in life from cardiac complications such as heart failure. Read More

Superficial angiomyxoma is a rare, benign, multilobulated cutaneous tumor composed of stellate and spindle cells, a prominent myxoid matrix, and numerous blood vessels. Superficial angiomyxoma may be indistinguishable from cutaneous lesions of the Carney complex, although superficial angiomyxoma can occur independently of the complex. In this article, we present the case of a 39-year-old Japanese woman with a 40 × 30 mm, focally ulcerated, polypoid superficial angiomyxoma on the left nipple without any evidence of Carney complex.

Previous studies evaluated cues for masked tone detection using reproducible noise waveforms. Human results founded on this approach suggest that tone detection is based on combined energy and envelope (ENV) cues, but detection cues in nonhuman species are less clear. Decision variable correlation (DVC) was used to evaluate tone-in-noise detection cues in the budgerigar, an avian species with human-like behavioral sensitivity to many complex sounds. Read More

The more than 80,000 chemicals in commerce present a challenge for hazard assessments that toxicity testing in the 21 century strives to address through high-throughput screening (HTS) assays. Assessing chemical effects on human development adds an additional layer of complexity to the screening, with a need to capture complex and dynamic events essential for proper embryo-fetal development. HTS data from ToxCast/Tox21 informs systems toxicology models, which incorporate molecular targets and biological pathways into mechanistic models describing the effects of chemicals on human cells, 3D organotypic culture models, and small model organisms.

Rationale: Primary melanin-producing tumors are rare extra-axial neoplasms OPEN of the central nervous system. In the literature, few case reports have discussed neoplasms involving the cavernous sinus; of these, only 4 have reported on neoplasms originating in Meckel cave. The diagnostic approach, including clinical and radiological analysis, is challenging, and cytopathological assessment with a molecular basis is the best approach to discriminate between these lesions.

The genetic landscape of pituitary adenomas (PAs) is diverse and many of the identified cases remain of unclear pathogenetic mechanism. Germline genetic defects account for a small percentage of all patients and may present in the context of relevant family history. Defects in (mutated in Familial Isolated Pituitary Adenoma syndrome or FIPA), (coding for , mutated in Multiple Endocrine Neoplasia type 1 or MEN 1), (mutated in Carney complex), (involved in X-Linked Acrogigantism or X-LAG), and (mutated in the so called "3 P association" of PAs with pheochromocytomas and paragangliomas or 3PAs) account for the most common familial syndromes associated with PAs.

Background: Atrial myxomas are generally considered benign neoplasms. The majority of tumors are sporadic and less than 10% are associated with an autosomal dominant condition known as the Carney complex, which is most often caused by germline mutation in the gene PRKAR1A. Whether this gene plays a role in the development of sporadic myxomas has been an area of debate, although recent studies have suggested that some fraction of sporadic tumors also carry mutations in PRKARIA.

In cardiac myxomas, the malignant transformation process, selecting incidental gene mutations and leading to loss of proliferation control, has not a so drastic effects in terms of growth rate of tumor mass, but frequently the particular location of lesion engrosses the high risk for health. For accurate cancer cell profiling, it is important to establish the embryologic origin of malignant cells and their initial commitments, above all, in the sight of therapeutic strategies and solutions. Here, we advance, for cardiac myxoma, the hypothesis of an origin from cardiac neural crest cells and we attempt to support it by an integrated discussion of current knowledge about embryological characteristics of neural crest cells and most recent studies focusing cardiac myxomas.
