Protein pre-mRNA processing factor 8 (PRPF8), a core component of the spliceosome, is integral to the splicing process, ensuring accurate gene transcription and spliceosome assembly. Disruptions in PRPF8 function are linked to a variety of cancers, as mutations in this gene can induce abnormal splicing events that contribute to tumorigenesis, metastasis, and drug resistance. This review provides an in-depth analysis of the mechanisms by which PRPF8 regulates tumorigenesis through AS, exploring its role in diverse cancer types, including breast, liver, myeloid, and colorectal cancers. Furthermore, we examine the molecular pathways associated with PRPF8 dysregulation and their impact on cancer progression.

Compared with the tumor-only group, we found that PE supplementation significantly improved body weight, muscle mass, maximum limb grip strength (MLGS), and myosin heavy chain expression in the muscles of tumor-bearing mice. PE also significantly inhibited the expression of factors related to protein degradation, oxidative stress, and inflammation, while enhancing the expression of antioxidant enzymes in tumor-bearing mice. These effects of PE were associated with an increased expression of phosphorylated Akt and forkhead box protein O1, along with a reduced expression of phosphorylated nuclear factor-κB p65 in the muscles of tumor-bearing mice. Furthermore, PE similarly increased MLGS and attenuated muscle atrophy in mice exposed to cisplatin by inhibiting protein degradation.

To enhance the synthesis of ergosterol and mycelial biomass in termite ball fungus, methyl jasmonate and salicylic acid were used to stimulate the biosynthesis of ergosterol compounds during the growth of TMB mycelium and relative quantitative levels of gene transcripts.

It contains high levels of sugar and protein and yields a large amount of biomass. Because of these characteristics, it is considered an efficient and cost-effective energy crop with various applications, including phytoremediation and fodder production. A pasteurization technique for this grass that is suited for the simplest formulation is simple and cost-effective for growing oyster mushrooms on small farms. This study used pasteurized <i>Cenchrus fungigraminus</i> as a substrate to grow three mushroom species: <i>Pleurotus ostreatus</i>, <i>Pleurotus pulmonarius</i> and <i>Pleurotus florida</i>. The aim was to evaluate their enzyme activities, growth rate, and yields. The findings demonstrated that the average growth rate of three species grown in pasteurized <i>C. fungigraminus</i> was between 25 days and 36 days.
