Liver cirrhosis.

Lancet 2021 Sep 17. Epub 2021 Sep 17.

Mayo Clinic College of Medicine and Science, Rochester, MN, USA.

Cirrhosis is widely prevalent worldwide and can be a consequence of different causes, such as obesity, non-alcoholic fatty liver disease, high alcohol consumption, hepatitis B or C infection, autoimmune diseases, cholestatic diseases, and iron or copper overload. Cirrhosis develops after a long period of inflammation that results in replacement of the healthy liver parenchyma with fibrotic tissue and regenerative nodules, leading to portal hypertension. The disease evolves from an asymptomatic phase (compensated cirrhosis) to a symptomatic phase (decompensated cirrhosis), the complications of which often result in hospitalisation, impaired quality of life, and high mortality.

tRNA-derived small RNAs: novel regulators of cancer hallmarks and targets of clinical application.

Cell Death Discov 2021 Sep 18;7(1):249. Epub 2021 Sep 18.

Department of Thoracic Surgery, Xiangya Hospital, Central South University, Xiangya Road 87th, Changsha, 410008, Hunan, P. R. China.

tRNAs are a group of conventional noncoding RNAs (ncRNAs) with critical roles in the biological synthesis of proteins. Recently, tRNA-derived small RNAs (tsRNAs) were found to have important biological functions in the development of human diseases including carcinomas, rather than just being considered pure degradation material. tsRNAs not only are abnormally expressed in the cancer tissues and serum of cancer patients, but also have been suggested to regulate various vital cancer hallmarks.

Tuberous sclerosis complex (TSC) is a relatively rare autosomal dominant neurocutaneous disorder secondary to mutations in the or tumor suppressor genes. Although manifestation of the classic triad of seizures, intellectual disability, and facial angio-fibromas may facilitate timely diagnosis of TSC, the multisystem features that may indicate TSC in the absence of these manifestations remain highly variable. In addition, patients with TSC are at risk of developing multiple benign and malignant tumors in various organ systems, resulting in increased morbidity and mortality. Read More

Sporadic superficial angiomyxomas demonstrate loss of PRKAR1A expression.

Histopathology 2021 Sep 17. Epub 2021 Sep 17.

Division of Anatomic Pathology, Mayo Clinic, Rochester, MN, USA.

Superficial angiomyxomas are cutaneous mesenchymal tumors that typically present clinically as slow-growing, solitary, asymptomatic nodules that can occur at any age. Histopathologically, these dermal and subcutaneous tumors are characterized by abundant myxoid stroma, numerous thin-walled and often arborizing blood vessels, and spindled to stellate fibroblast-like cells. While usually sporadic, superficial angiomyxomas can occasionally be associated with Carney complex (CNC), an autosomal dominant disorder characterized by inactivating germline mutations in the 1-alpha regulatory subunit of protein kinase A (PRKAR1A) and various clinical manifestations, including: cardiac myxomas, facial lentigines, epithelioid blue nevi, endocrinopathies, and psammomatous melanotic schwannomas.
