Palindrome-mediated DNA nanotubes with cell-specific aptamers to improve targeted antitumor effects and reduce toxicity on non-small cell lung cancer.

Chemotherapy is regarded as a widely used and effective treatment strategy for lung cancer, although most conventional chemotherapeutics cause severe toxic side-effects due to their indiscriminate attacks on both cancerous and normal cells. Although nucleic acid nanomaterials are emerging as a promising drug delivery strategy, their clinical applications are limited by rapid degradation by nucleases and difficulties in targeting cancer cells. In this study, we have developed a Rhein-loaded aptamer-based DNA nanotube (DNT-S6@Rhein) for the targeted and efficient therapy of non-small cell lung cancer.

Whole-Genome Sequencing of the Entomopathogenic Fungus KMZW-1 and Its Efficacy Against .

KMZW-1 is recognized for its potential as a biocontrol agent against agricultural and forestry pests, particularly due to its compatibility with integrated pest management (IPM) strategies. This study aimed to investigate the complete genome of KMZW-1 and assess its pathogenicity against . Whole-genome sequencing revealed a genome size of 47,239,278 bp, comprising 27 contigs, with a GC content of 51.

Circ-Ntrk2 acts as a miR-296-5p sponge to activate the TGF-β1/p38 MAPK pathway and promote pulmonary hypertension and vascular remodelling.

Background: Circular RNAs (circRNAs), a novel class of non-coding RNAs, play an important regulatory role in pulmonary arterial hypertension (PAH); however, the specific mechanism is rarely studied. In this study, we aimed to discover functional circRNAs and investigate their effects and mechanisms in hypoxia-induced pulmonary vascular remodelling, a core pathological change in PAH.

Methods: RNA sequencing was used to illustrate the expression profile of circRNAs in hypoxic PAH.

Comparison of hypoxia-induced pulmonary hypertension rat models caused by different hypoxia protocols.

Pulmonary hypertension (PH) is a serious and even fatal disorder with limited treatment strategies. The hypoxia-induced pulmonary hypertension (HPH) rat model is commonly used in this field. While the HPH rat model has strong predictability and repeatability, the model is a chronic model, making it time-consuming, costly, and complicated and limiting the progress of the experiments.
