Summary: This study found that the lncRNA BBOX1-AS1 promotes tumor progression and drug resistance in HCC by upregulating PHF8. BBOX1-AS1 enhances the stability of PHF8 mRNA by targeting miR-361-3p, leading to tumor progression and autophagy. These findings suggest that BBOX1-AS1 promotes HCC progression and sorafenib resistance through the miR-361-3p/PHF8 axis.

Summary: The study found that fasting can inhibit glycolysis and mitochondrial function in papillary thyroid carcinoma (PTC). Fasting significantly increases the expression of lncRNA PRKCQ-AS1 in PTC cells, which leads to suppression of glycolysis and reduced mitochondrial function. PRKCQ-AS1 interacts with IGF2BPs and enhances the expression of PRMT7 mRNA, thereby regulating glycolysis and mitochondrial function in PTC and inhibiting tumor growth.

Summary: Our study found that the lncRNA CSNK1G2-AS1 is significantly downregulated in TGCTs compared to normal testis, and hypomethylation of CSNK1G2-AS1 is associated with a better prognosis in TGCT patients. Overexpression of CSNK1G2-AS1 promotes proliferation, migration, and invasion of TGCT cells while inhibiting apoptosis, possibly through the EMT and AKT pathways.

Summary: Mounting evidence suggests that obscurin, a giant cytoskeletal protein, is involved in the predisposition and development of breast cancer. Low levels of obscurin correlate with reduced overall and relapse-free survival in breast cancer patients. The antisense lncRNA OBSCN-AS1 regulates obscurin expression and functions as a metastasis suppressor, potentially serving as prognostic biomarkers and therapeutic targets for metastatic breast cancer.

Summary: This study presents a flexible statistical procedure to detect gene-environment interaction (GxE) regardless of whether the underlying relationship is linear or not. By modeling the joint genetic and GxE effects as a varying-coefficient function of the environmental factor, the proposed model is able to capture dynamic trajectories of GxE. A likelihood ratio test with a fast Monte Carlo algorithm is employed for hypothesis testing. Simulations and real data analysis demonstrate the validity and power of the proposed model in various settings, especially for nonlinear GxE.

Summary: By exploiting aptamers as targeting warheads, we developed a strategy for inducible degradation of undruggable proteins, thereby inhibiting cancer cell proliferation. To reduce on-target toxicity, we further developed a light-controllable PROTAC that can release the targeting warhead through UV irradiation, leading to target activation and degradation.

Summary: Identification of new genetic signals associated with susceptibility to complex human diseases is crucial for disease diagnosis, prevention, and treatment. This study compares the power of the Jonckheere-Terpstra (JT) trend test and the Cochran-Armitage (CA) trend test under different scenarios, and shows that the JT trend test outperforms the CA trend test in terms of statistical power in certain circumstances, especially when the sample size is small and the minor allele frequency is low. Overall, the JT trend test is a valuable alternative to the CA trend test for better detection of genetic signals and a finer understanding of their genetic architecture.

Summary: Viruses rely on host ribosomes for protein synthesis, but the specific factors involved in translation of viral RNAs are not fully understood. Through a CRISPR screen, researchers identified multiple host factors, including 60S ribosome biogenesis proteins, that are required for viral protein synthesis. In addition, the study revealed the importance of SBDS and SPATA5 in viral replication for a wide range of viruses.

Summary: Current malaria treatments face drug resistance and there is an urgent need for new drugs. Through a screening process, we discovered (S)-SW228703 ((S)-SW703), a tyrosine amide with activity against asexual blood and liver stages of malaria and a fast-killing profile. Resistance to (S)-SW703 is associated with mutations in the Plasmodium falciparum cyclic amine resistance locus (Pf CARL) and P. falciparum acetyl CoA transporter (PfACT), similar to other compounds with fast and liver-stage activity. The exact mechanism of action or binding mode of these compounds, which are thought to act in the endoplasmic reticulum (ER), remains unknown. (S)-SW703 provides a new chemical series with broad activity against multiple life-cycle stages and a fast-killing mechanism of action, which can be further optimized for the development of new malaria treatments.

Summary: Glycosaminoglycans (GAGs) are linear polysaccharides with negative charges, composed of uronic acid and amino sugars. The bladder epithelium is covered by a layer of GAGs, which are believed to serve as a protective barrier and potential interaction site for the urinary microbiome. This study investigated urinary GAG composition in postmenopausal women and found that chondroitin sulfate (CS) is the major GAG. The study also identified an elevation of urinary CS in women with active recurrent urinary tract infection (rUTI). Additionally, the study revealed associations between urinary GAGs and urobiome composition, including specific bacterial species associated with different GAG types and vaginal dysbiosis.

Summary: Interferons control viral infection by inducing the expression of antiviral effector proteins encoded by interferon-stimulated genes (ISGs). Using CRISPR-based loss-of-function screens, this study identified a limited set of ISGs that mediate interferon-mediated suppression of Venezuelan equine encephalitis virus (VEEV). Combinatorial gene targeting revealed that three antiviral effectors, ZAP, IFIT3, and IFIT1, together constitute the majority of interferon-mediated restriction of VEEV, while accounting for < 0.5% of the interferon-induced transcriptome. These findings suggest a refined model of the antiviral interferon response.

Summary: In this study, the formation of biomolecular condensates by the oncogenic fusion protein BRD4-NUT and its associated histone acetyltransferase p300 were investigated. The researchers found that a minimal fragment of NUT fused with BRD4 is sufficient to bind p300 and form condensates. The results suggest a model for condensate formation involving positive feedback and phase separation, and identify different regions of p300 that contribute to condensate formation and transcriptional regulation.

Summary: The use of AAV capsid libraries with selection strategies has successfully generated novel AAVs with enhanced features. However, the inability to sequence the complete capsid gene in a high-throughput manner has limited capsid engineering. To overcome this limitation, AAV capsid shuffled libraries were generated and directed evolution was applied in mice and non-human primates to yield AAVs compatible for translational applications. The use of single molecule real-time sequencing and nuclei-enrichment step provided insights for variant identification in the central nervous system.

Summary: Neurofibromatosis type 1 (NF1) is a common tumor-predisposing genetic disorder characterized by the development of benign neurofibromas. This study explored the mechanism of extracellular matrix (ECM) deposition during neurofibroma development and treatment response. The researchers found that basement membrane (BM) proteins, rather than major collagen isoforms, were upregulated in the ECM during plexiform neurofibroma (pNF) development. They also identified TGF-β1 signaling as a key regulator of ECM dynamics and demonstrated that TGF-β1 overexpression promoted pNF progression. The findings suggest that BM proteins could serve as biomarkers for diagnosing and monitoring the treatment response of NF1.
