Article Synopsis
  • Exosomal PD-L1 is being recognized as a promising noninvasive biomarker for predicting how well patients will respond to immunotherapy, but current methods for monitoring it are challenging due to the complexity of its biological environment and poor isolation techniques.
  • A new method has been developed involving a Tim4-functionalized magnetic core-shell framework (FeO@SiO-ILI-01@Tim4) that allows for more effective and efficient isolation of exosomes, achieving a capture efficiency of over 90%.
  • This innovative approach not only purifies exosomes significantly better than traditional methods but also allows for high-throughput, noninvasive detection of exosomal PD-L1, resulting in a prognosis accuracy of 85.7%, which

Background: Acquired resistance is inevitable in non-small cell lung cancer (NSCLC) patients treated with epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs). The emergence of exon 20 C797S is one of the major resistance mechanisms to osimertinib as a third-generation EGFR-TKI. To date, there is no standard of care for NSCLC patients after acquiring C797S.

Background: Lung adenocarcinoma (LUAD) is the most common subtype of nonsmall-cell lung cancer (NSCLC) and has a high incidence rate and mortality. The survival of LUAD patients has increased with the development of targeted therapeutics, but the prognosis of these patients is still poor. Long noncoding RNAs (lncRNAs) play an important role in the occurrence and development of LUAD.

The LIM domain only 1 (LMO1) gene belongs to the LMO family of genes that encodes a group of transcriptional cofactors. This group of transcriptional cofactors regulates gene transcription by acting as a key "connector" or "scaffold" in transcription complexes. All LMOs, including LMO1, are important players in the process of tumorigenesis.

Exosomes have become the most ideal analysis target for liquid biopsy since they carry a large amount of genetic materials. The study on exosomes has great significance for cancer diagnosis and prognosis. However, the extremely low concentration renders the development of a robust exosomes enrichment technique, with the merits of low nonspecific cell adhesion, high-capture efficiency, and easy nondestructive release of captured exosomes, of vital significance.

Objective: To explore the therapeutic effect of interleukin-11 (IL-11) on high-dose methotrexate (HDMTX) induced mucositis in Wistar's rats, the proliferative effect on CEM leukemia cell line and the antitumor effect on HDMTX.

Methods: Ninety-five 5-week old, 120 - 150 grams weight Wistar rats were randomly divided into five groups. Group A is normal control (n = 15), group B MTX control (n = 20), group C IL-11 pretreatment group before MTX injection (n = 20), group D (n = 20) the high dose IL-11 group (475 microg.
