lncRNAs dysregulation in monocytes from primary antiphospholipid syndrome patients: a bioinformatic and an experimental proof-of-concept approach.

Background: Antiphospholipid syndrome (APS) is the main cause of acquired thrombophilia where peripheral circulating cells such as monocytes have a key role. Currently, several studies have linked long non-coding RNAs (lncRNAs) in different inflammatory and autoimmune processes, including lupus. However, the role of lncRNAs in antiphospholipid syndrome is unknown, therefore, we aimed to select and measure expression levels of three lncRNAs based on its abundance in monocytes from APS patients.

Negative Effects of Chronic High Intake of Fructose on Lung Diseases.

In the modern diet, excessive fructose intake (>50 g/day) had been driven by the increase, in recent decades, of the consumption of sugar-sweetened beverages. This phenomenon has dramatically increased within the Caribbean and Latin American regions. Epidemiological studies show that chronic high intake of fructose related to sugar-sweetened beverages increases the risk of developing several non-communicable diseases, such as chronic obstructive pulmonary disease and asthma, and may also contribute to the exacerbation of lung diseases, such as COVID-19.

Myocardial expression of transforming growth factor beta family and endothelin-1 in the progression from heart failure to ascites in broilers with cold-induced pulmonary hypertension.

We determined mRNA expression of genes of endothelin-1 (ET-1), and of the transforming growth factor beta ligands (TGFβ1, TGFβ2 and TGFβ3), their receptors (TβRI and TβRII) and their pseudoreceptor BAMBI in the heart of broilers raised under cold temperature conditions and affected by pulmonary hypertension. Gene expression was determined by RT-qPCR in right myocardial ventricle samples from 4-week-old chickens (n = 48) raised either under normal (control) or cold temperature conditions (22 °C versus 14 °C). We do not find differences among healthy birds, birds with cardiac failure and ascitic birds in the mRNA levels of TGFβ2, TGFβ3 and BAMBI.

Over, and underexpression of endothelin 1 and TGF-beta family ligands and receptors in lung tissue of broilers with pulmonary hypertension.

Transforming growth factor beta (TGF β ) is a family of genes that play a key role in mediating tissue remodeling in various forms of acute and chronic lung disease. In order to assess their role on pulmonary hypertension in broilers, we determined mRNA expression of genes of the TGF β family and endothelin 1 in lung samples from 4-week-old chickens raised either under normal or cold temperature conditions. Both in control and cold-treated groups of broilers, endothelin 1 mRNA expression levels in lungs from ascitic chickens were higher than levels from healthy birds (P < 0.
