Leukemia covers a broad category of cancer malignancies that specifically affect bone marrow and blood cells. While different kinds of leukemia have been identified, effective treatments are still lacking for most forms, and even those treatments considered effective can lead to relapses. MicroRNAs, or miRNAs, are short endogenous non-coding single-stranded RNAs that help control the epigenetics of gene expression.

CIC::DUX4 fusion sarcoma represents a rare and aggressive subtype of undifferentiated small round blue cell tumors. We report on a 23-year-old African male who developed a rapidly enlarging inferolateral left buttock nodule with ulceration. After debulking excision of the lesion, histologic sections demonstrated sheets and lobules of atypical round blue cells with significant cytologic atypia.

Background And Aims: Osteopontin (OPN) promotes the ductular reaction and is a major driver of chronic liver disease (CLD) progression. Although CLD is characterised by the accumulation of inflammatory cells including macrophages around the peri-portal regions, the influence of OPN on recruitment is unclear. We investigated the role of OPN in cholangiocyte chemokine production and macrophage recruitment by combining in vivo, in vitro, and in silico approaches.

Objectives: Immune checkpoint inhibitors (ICIs) are associated with immune-related adverse events (irAEs), of which endocrinopathies are common. We characterized endocrine and non-endocrine irAEs in cancer patients receiving ICIs, identified risk factors for their development and established whether endocrine and non-endocrine irAEs were differentially associated with improved cancer prognosis.

Design And Methods: Single-center, retrospective cohort study of patients with advanced or metastatic solid tumors receiving at least one ICI treatment cycle (242 men, 151 women, median age 65 years).

Article Synopsis
  • - MiRNAs are small non-coding RNA molecules that regulate gene expression by binding to mRNA, leading to its degradation or repression, with their biogenesis involving several detailed steps such as transcription and processing.
  • - Colorectal cancer, a common and serious disease with low early diagnosis rates and high metastasis, is influenced by genetic and epigenetic factors, especially miRNAs, which can act as tumor suppressors or oncogenes depending on their target genes.
  • - MiRNAs show promise as biomarkers for colorectal cancer due to their stability and ease of detection in body fluids, enabling differentiation between cancer patients and healthy individuals, predicting cancer stage, and monitoring responses to treatment.

Despite its considerable and growing burden, there are currently no Food and Drug Administration-approved treatments for metabolic dysfunction-associated steatotic liver disease or its progressive form, metabolic dysfunction-associated steatohepatitis (MASH). Several glucagon-like peptide-1 receptor agonists (GLP-1RAs) and other agents are in various phases of clinical development for use in MASH; an ideal therapy should reduce liver fat content, improve chronic liver disease, help mitigate metabolic comorbidities and decrease all-cause mortality. Because of interconnected disease mechanisms, metabolic dysfunction-associated steatotic liver disease/MASH often coexists with type 2 diabetes (T2D), obesity and cardiovascular disease.

Article Synopsis
  • NAFLD (non-alcoholic fatty liver disease) affects bile acid transporters in the liver, impacting their function and distribution across different zones in the liver.
  • Using a machine learning approach, researchers analyzed liver biopsies to quantify the localization and abundance of key bile acid transporters in non-diseased, NAFL, and NASH (non-alcoholic steatohepatitis) samples.
  • Findings revealed that NAFLD led to significant changes in the membrane localization of transporters, particularly BSEP and OATP1B3, which are linked to altered bile acid homeostasis and potentially contribute to disease progression.
