Summary: The DEAD-box helicase (DDX) family plays a critical role in cancer initiation and progression through alternative splicing, transcription, and ribosome biogenesis. DDX56, a member of this family, is overexpressed in several cancers and exhibits an oncogenic role. This study demonstrated the aberrant expression of DDX56 in gastric cancer through high-throughput sequencing and functional studies, shedding light on its biological role and potential therapeutic target in gastric cancer.

Summary: Genetic mutations in heat shock factor 4 (Hsf4) are linked to congenital and age-related cataracts. Hsf4 acts as a suppressor of p21(cip1) expression and plays an anti-senescence role in lens epithelial cells. Hsf4 protects against cellular senescence during lens development and aging by fine-tuning p21(cip1) expression.

Summary: p21 plays a crucial role in driving keratinocytes towards differentiation in response to genomic stress by intervening in the mitosis block. Loss of p21 allows cells to escape differentiation and continue proliferation, while also driving keratinocytes from differentiation to apoptosis.

Summary: This study reveals the uncharacterized function of lncRNA Malat1 in cancer-associated aging. It shows that Malat1 interacts with different proteins in the brain of young mice and aged mice. The study also identifies the differential expression of two Malat1 isoforms in retina and brain, indicating their roles in gene regulation. Moreover, the study demonstrates the impact of these isoforms on retinal oxidative stress and corneal opacity with age.

Summary: SNHG18 is significantly downregulated in bladder cancer tissues and cell lines. It inhibits c-Myc expression by modulating the ubiquitination-proteasome pathway, leading to the transcription and expression of p21. This finding reveals a novel regulatory mechanism involving the SNHG18/c-Myc/p21 pathway in bladder cancer pathogenesis and provides potential lncRNA-based diagnostics and therapeutics for bladder cancer.

Summary: Host factors such as age, sex, obesity, and other comorbidities can impact the effectiveness of COVID-19 vaccines. A study identified healthcare workers with unexpectedly low antibody levels after receiving the BNT162b2 vaccine. These individuals had fewer antibody-producing cells and weaker T cell responses, potentially due to premature lymphocyte aging.

Summary: Patients with advanced bladder cancer often develop chemoresistance, leading to tumor recurrence. In this study, the senescence program in solid tumors was shown to improve short-term drug sensitivity. The important role of c-Myc in bladder cancer cell senescence was determined using bioinformatics analysis. The study also revealed that reducing the expression levels of c-Myc and HSP90B1 could inhibit bladder cancer cell proliferation, promote cellular senescence, and enhance cisplatin chemosensitivity. The HSP90B1/c-Myc interaction was found to regulate the p21 signaling pathway, which affects cisplatin sensitivity by modulating bladder cancer cell senescence.

Summary: This study reveals that increased RAB27B in leukaemia stem cells (LSCs) inhibits senescence and maintains stemness through the regulation of exosome secretion. The increased RAB27B promotes the loading and release of senescence-inducing proteins in exosomes, and the exosomes derived from RAB27B-regulated LSCs induce senescence of mesenchymal stem cells (MSCs). In turn, the senescent MSCs facilitate LSC maintenance through the selective excretion of exosomes enriched with stemness-promoting proteins.

Summary: One major obstacle in diabetes is the hyperglycemic memory, which lacks specific therapies. In diabetic kidney disease (DKD), glucose-mediated changes in gene expression persist even after reversing hyperglycemia. The gene p21, associated with the p53-p21 pathway, is found to be consistently induced by hyperglycemia and linked to DKD severity. The sustained expression of p21 in DKD is associated with demethylation of its promoter and reduced DNMT1 expression. Two disease resolving agents, 3K3A-aPC and parmodulin-2, can reverse the sustained p21 expression, tubular senescence, and DKD, highlighting p21 as a potential therapeutic target for hyperglycemic memory in DKD.

Summary: Loss of AP4 in breast cancer cells leads to DNA damage, senescence, and reduced proliferation. Deletion of p53 can reverse the senescence and proliferation defects in AP4-deficient cells. Loss of AP4 enhances the repression of DREAM and E2F target genes induced by c-MYC through p53.

Summary: Intrahost analysis of SARS-CoV-2 genomic sequences identified 2 viral haplotypes with 3 genetically linked mutations from a patient's respiratory and intestinal tracts. The spatiotemporal data suggest that the patient initially had dual infection of 2 SARS-CoV-2 variants, which then redistributed into the two systems.

Summary: Chromosomal translocation leads to the formation of the EWS-FLI1 fusion oncogene in Ewing sarcoma, with SPOP identified as the E3 ligase and OTUD7A as the deubiquitinase regulating EWS-FLI1 protein stability. Targeting OTUD7A with the inhibitor 7Ai shows potential as a therapeutic strategy for Ewing sarcoma dependent on EWS-FLI1 and related fusions.

Summary: This study analyzes clinical samples from patients with COVID-19 and finds that genetic diversity increases in individuals after symptom onset. Nonsynonymous mutations are more common within individuals but less prevalent at the population level, suggesting a two-step fitness selection process. Dynamic changes in iSNVs among different populations indicate differences in the fitness selection process.

Summary: This study found that serum 2-OG levels in cholangiocarcinoma patients are associated with the effectiveness of chemotherapy. Patients with progressive disease showed significantly higher levels of serum 2-OG compared to stable disease and partial response patients. The study also revealed that overexpression of ASPH mimics the effects of 2-OG, and knockdown of ASPH improves chemotherapy. Targeting ASPH enhances the effects of chemotherapy by modulating ATM and ATR, two key regulators of DDRs.
