Summary: In this study, it was found that MIR516A is upregulated in human bladder cancer, acting as an oncogene by regulating PHLPP2 and inhibiting autophagy, thus promoting tumor growth. This novel oncogenic function of MIR516A in bladder cancer differs from its known tumor suppressor role in other cancers.

Summary: Mucus secretion from colonic goblet cells is regulated by autophagy and endoplasmic reticulum stress. Pharmacological reduction of ER stress or activation of the UPR in mice leads to excess mucus secretion. This regulation is dependent on the gut microbiota and the intracellular sensor NOD2, and excess mucus production protects against inflammation.

Summary: BECN1 plays a crucial role in adipocyte differentiation, lipolysis, and insulin resistance. Mutation at the acetylation site K414 of BECN1 affects the stability of the protein, influencing autophagy, differentiation, and lipolysis in adipocytes. These findings suggest that K414 of BECN1 may serve as a potential drug target for regulating autophagy and lipid metabolism in adipocytes.

Summary: The roles of enhancer RNAs (eRNAs) in gene expression regulation in human diseases have been increasingly recognized. However, little is known about the specific expression profile and function of eRNAs in oral squamous cell carcinoma (OSCC). This study aimed to investigate an uncharacterized eRNA, insulin receptor substrate 2 enhancer RNA (IRS2e), in OSCC. IRS2e was found to be overexpressed in OSCC and correlated with poor prognosis. Knockdown of IRS2e inhibited cell growth, induced apoptosis and cell cycle arrest in OSCC cells. Furthermore, IRS2e ablation inhibited tumor growth in vivo. Mechanistically, IRS2e was essential for the expression of nearby oncogene IRS2. Overall, IRS2e is a novel oncogenic eRNA required for IRS2 expression in OSCC.

Summary: The inclusion level of Ki67 exon 7 is significantly associated with poor prognosis in multiple cancer types, and is essential for cell proliferation, cell cycle progression, cell migration, and tumorigenesis in head and neck squamous cell carcinoma (HNSCC). Additionally, it is positively correlated with intracellular reactive oxygen species (ROS) level. The study also identified a new regulatory axis involving SRSF3/Ki67/AKR1C2 during HNSCC tumor progression.

Summary: The lack of PD-L1 exon 3 leads to a significant loss of cellular membrane locations and reduced protein expression of PD-L1. Oral cancer cells do not skip exon 3 to ensure the expression of full-length, functional PD-L1 protein. Two key exonic splicing enhancers (ESEs) were discovered for exon 3 inclusion, and two efficient antisense oligonucleotides (ASOs) were identified to block these ESEs. Treatment with these ASOs enhances immune cells' ability to suppress cancer cell proliferation and also inhibits cell growth and induces cell pyroptosis in oral cancer cells.

Summary: ITGB4 plays an important role in mediating cell adhesion and has been implicated in tumorigenesis and metastasis. This study examined the expression of ITGB4 in oral squamous cell carcinoma (OSCC) and its relationship with other markers. The results showed that ITGB4 was significantly increased in OSCC, and a subgroup with high expression of ITGB4/PD-L1 and CD8/PD-1 had a better prognosis. These findings shed light on the potential role of ITGB4 in OSCC and provide a basis for further investigation.

Summary: In this study, the function and potential mechanism of Fto in dentine formation were investigated. Fto knockout in mice led to defects in dentine formation, with decreased mineralization ability and altered expression of odontoblastic mineralization related genes. Fto knockdown also affected the inclusion level of Runx2 exon 5 and destabilized RBM4 mRNA. These findings suggest that Fto plays a critical role in dentine formation.

Summary: In this study, the researchers used signal analysis to study the instantaneous amplitude and phase of sarcomeric oscillations in skeletal muscle. They identified two types of oscillations, sarcomeric oscillations and sarcosynced oscillations, and visualized their behavior during propagating waves. The researchers discovered the presence of sarcomeric defect holes and sarcomeric collision holes, which are important indicators for understanding the oscillation properties of sarcomeres. This finding has important implications for improving our understanding of muscle function and its regulatory mechanisms.

Summary: This study found that low expression of TP53INP2 is associated with poor survival in colorectal cancer (CRC) patients. As the malignancy of CRC progresses, TP53INP2 expression gradually decreases. Knockdown of TP53INP2 promotes CRC cell proliferation and tumor growth. Mechanistically, TP53INP2 deficiency decreases phosphorylation of beta-catenin, leading to increased accumulation and enhanced nuclear translocation and transcriptional activity. Additionally, TP53INP2 sequesters TIM50, inhibiting its activation of beta-catenin. In conclusion, downregulation of TP53INP2 promotes CRC progression by activating beta-catenin.

Summary: Oligomeric enzymes are known for their higher catalytic rates compared to monomeric enzymes, but the extent of additivity in their activity is still not well understood. This study used tetrameric rabbit lactate dehydrogenase as a model to examine the kinetics of its catalytic action. Surprisingly, when the concentration of the limiting reactant exceeded that of a single subunit, there was a significant slowdown in the enzyme's conformational rearrangements.
