MicroRNA dysregulation and its impact on apoptosis-related signaling pathways in myelodysplastic syndrome.

Myelodysplastic syndrome (MDS) holds a unique position among blood cancers, encompassing a spectrum of blood-related disorders marked by impaired maturation of blood cell precursors, bone marrow abnormalities, genetic instability, and a higher likelihood of progressing to acute myeloid leukemia. MicroRNAs (miRNAs), short non-coding RNA molecules typically 18-24 nucleotides in length, are known to regulate gene expression and contribute to various biological processes, including cellular differentiation and programmed cell death. Additionally, miRNAs are involved in many aspects of cancer development, influencing cell growth, transformation, and apoptosis.

Unfolded Protein Response Signaling in Hepatic Stem Cell Activation in Liver Fibrosis.

Frequent exposure to various external and internal adverse forces (stresses) disrupts cell protein homeostasis through endoplasmic reticulum (ER) capacity saturation. This process leads to the unfolded protein response (UPR), which aims to re-establish/maintain optimal cellular equilibrium. This complex mechanism is involved in the pathogenesis of various disorders, such as metabolic syndrome, fibrotic diseases, neurodegeneration, and cancer, by altering cellular metabolic changes integral to activating the hepatic stellate cells (HSCs).

A spotlight on the interplay between Wnt/β-catenin signaling and circular RNAs in hepatocellular carcinoma progression.

Hepatocellular carcinoma (HCC) is one of the deadliest cancers due to multifocal development and distant metastasis resulting from late diagnosis. Consequently, new approaches to HCC diagnosis and treatment are required to reduce mortality rates.

Potential Immune Indicators for Predicting the Prognosis of COVID-19 and Trauma: Similarities and Disparities.

Although cellular and molecular mediators of the immune system have the potential to be prognostic indicators of disease outcomes, temporal interference between diseases might affect the immune mediators, and make them difficult to predict disease complications. Today one of the most important challenges is predicting the prognosis of COVID-19 in the context of other inflammatory diseases such as traumatic injuries. Many diseases with inflammatory properties are usually polyphasic and the kinetics of inflammatory mediators in various inflammatory diseases might be different.
