Colorectal cancer (CRC) is the third most common cancer type and the second highest mortality rate among cancers. However, the mechanisms underlying CRC progression remain to be fully understood. In this work, a recently identified mA-modified RNA reader protein Proline-rich Coiled-coil 2a (PRRC2A) is markedly upregulated in CRC, and intestinal epithelium-specific deletion of Prrc2a significantly suppressed tumor cell growth, stemness, and migratory capacity, while its overexpression promoted these behaviors.

Background: Lung metastasis is the leading cause of death in patients with osteosarcoma (OS), and new drugs are urgently needed. Epigenetic reprogramming is a recently proposed hallmark of malignancy; therefore, targeting epigenetic enzymes might provide a novel therapeutic strategy for OS lung metastasis. We recently reported that ailanthone (AIL), a natural product isolated from the Chinese medicinal plant Ailanthus altissima, inhibits OS cell growth and induces substantial metabolic changes; however, its direct targets remain unclear.

The rising prevalence of cesarean sections, abortions, and other surgical interventions involving the uterus has led to an increased incidence of acquired uterine arteriovenous malformations (AVMs). These malformations primarily present as vaginal bleeding, which can significantly impair the quality of life for affected individuals and can pose life-threatening risks in severe instances. Currently, there exists considerable variability in the clinical manifestations, treatment indications, and outcomes associated with uterine AVMs, which substantially complicates clinical diagnosis and management.

Irritable bowel syndrome (IBS) is a common intestinal disease characterized by abdominal pain, abdominal distension and irregular defecation frequency, and it has had a high incidence and low cure rate in recent years. Visceral hypersensitivity (VH) is one of the main physiological indicators of IBS, and TRPV1 and TRPM8 (transient receptor potential vanilloid 1 and melastatin 8) play crucial roles in VH and are widely distributed in the intestine, significantly impacting abdominal pain in IBS patients. Under the guidance of PRISMA, four databases were systematically searched at the outset, including PubMed, Web of Science, Embase, and Cochrane Library.

A compact common-path off-axis digital holographic imaging method is proposed utilizing polarization-angular-multiplexing for Jones matrix measurement. Our method employs a common-path off-axis configuration to capture multiplexed off-axis interferograms generated by orthogonally polarized object beams and a reference beam on a monochrome CCD camera. The modulation of the fringe direction is achieved by two homemade retro-reflector mirrors, allowing for the retrieval of the Jones matrix distribution of transparent specimens through a matrix-division algorithm.

Multicomponent reactions - those where three or more substrates combine into a product - have been highly useful in rapidly building chemical building blocks of increased complexity, but achieving this enzymatically has remained rare. This limitation primarily arises because an enzyme's active site is not typically set up to address multiple substrates, especially in cases involving multiple radical intermediates. Recently, chemical catalytic radical sorting has emerged as an enabling strategy for a variety of useful reactions.
