Circular RNAs as Biomarkers in Breast Cancer Diagnosis, Prognosis, Molecular Types, Metastasis and Drug Resistance.

Breast cancer is one of the leading causes of cancer-related deaths in women worldwide. Circular RNAs (circRNAs), a novel class of endogenous noncoding RNA with a covalently closed continuous loop that lacks the 5'-cap structure and the 3'-poly A tail, are more stable than linear RNAs and less susceptible to degradation by nucleases. CircRNAs are widespread in multiple mammalian genomes and have been detected in various tissues, cells and body fluids.

Mutation of SMARCA4 Induces Cancer Cell-Intrinsic Defects in the Enhancer Landscape and Resistance to Immunotherapy.

Cancer genomic studies have identified frequent alterations in genes encoding components of the SWI/SNF chromatin remodeling complex, including SMARCA4 and ARID1A. Importantly, clinical reports indicate that SMARCA4-mutant lung cancers respond poorly to immunotherapy and have dismal prognosis. Here, we corroborated the clinical findings by using immune-humanized, syngeneic, and genetically engineered mouse models of lung cancer harboring SMARCA4 deficiency.

Coding circular RNA in human cancer.

circular RNA (circRNA) is a covalently closed single-stranded RNA that lacks 5' and 3' ends and has long been considered a noncoding RNA. With the development of high-throughput sequencing and bioinformatics technology, the understanding of circRNA has become increasingly advanced. Recent studies have shown that some cytoplasmic circRNAs can be effectively translated into detectable proteins, further indicating the importance of circRNA in cellular pathology and physiological functions.

A case report of breast Rosai-Dorfman disease and a literature review.

Rosai-Dorfman disease (RDD) is a rare idiopathic histiocytoproliferative disease that usually affects the lymph nodes of the head and neck, but can also involve extranodal sites such as the skin, sinuses, and soft tissues. Breast RDD is exceedingly rare. It may be clinically and radiographically similar to neoplastic and non-neoplastic diseases.

A long-term decline in downward surface solar radiation.

Downward surface solar radiation (DSSR) is critical for the Earth system. It is well-known that DSSR over land has fluctuated on decadal timescales in the past. By utilizing a combination of station observations and the latest CMIP6 simulations, here we show that DSSR had a global consistent decline during 1959-2014, with comparable contributions from greenhouse gases (GHGs) and anthropogenic aerosols.

Agricultural production is severely affected by environmental stresses such as drought, and deep rooting is an important factor enhancing crop drought avoidance. H-ATPases provide a transmembrane proton gradient and are thought to play a crucial role in plant growth and abiotic stress responses. However, their expression under abiotic stress and function on deep rooting is poorly understood in rice.

Hybrid prodrug nanoassembly for hypoxia-triggered immunogenic chemotherapy and immune modulation.

Tumor hypoxia is a critical driver of cancer progression, metastasis, and therapy resistance, posing significant challenges in effective cancer treatment. Hypoxia-activable prodrugs offer a promising strategy to target tumors in low-oxygen conditions, but their efficacy is often hindered by intrinsic properties and extrinsic cues. In this study, we developed a dual-prodrug nanoassembly system (CPPA) composed of a hypoxia-triggerable camptothecin (CPT)-based dimeric prodrug (CP) and a lipid-conjugated STAT3 antisense oligonucleotide (ASO) prodrug (PA), aiming to enhance tumor-targeted chemotherapy and overcome the immune evasion within the tumor microenvironment.

Substrate-Mediated Growth of Au Nanowires Under Weak CTAB Control and Rapid Au Deposition.

The selective Au deposition at the Au-substrate interface is known to give ultrathin Au nanowires and the synthesis usually employs strong thiol-based ligands. It is shown that, by increasing the rate of Au deposition, weak cetyltrimethylammonium bromide (CTAB) can be made to behave like a strong ligand, so that it induces Active Surface Growth and gives Au nanowires. The ligand strength also depends on the packing interactions in the ligand layer, in the order of CTAB, CTAB, and CTAB.

Corticosteroids plus metformin versus corticosteroids as front-line treatment for patients with newly diagnosed ITP and pre-existing type 2 diabetes mellitus: A multicentre propensity score-matched study.

Corticosteroids are the standard first-line treatment for primary immune thrombocytopenia (ITP), with a high initial response but unsatisfactory sustained response (SR). Additionally, corticosteroids usually lead to hyperglycaemia especially in patients with pre-existing type 2 diabetes mellitus (T2DM). Besides reducing the blood glucose levels, metformin was found to have immunomodulatory effects.
