Precise identification of somatic and germline variants in the absence of matched normal samples.

Somatic variants play a crucial role in the occurrence and progression of cancer. However, in the absence of matched normal controls, distinguishing between germline and somatic variants becomes challenging in tumor samples. The existing tumor-only genomic analysis methods either suffer from limited performance or insufficient interpretability due to an excess of features.

Targeting IL-20 alleviates inflammatory mechanical allodynia and reduces epidural fibrosis in post-laminectomy syndrome rat model.

Background: Post-laminectomy syndrome (PLS) manifests as recurrent chronic back pain, with or without radiating leg pain, affecting 10-40% of patients following laminectomy. While surgical interventions can alleviate recurrent disc herniation or joint instability, medical management of PLS remains challenging due to unsatisfactory outcomes. Epidural fibrosis is a frequent cause of PLS, leading to nerve root tethering and dural sac compression.

Advances in biomarkers for immunotherapy in small-cell lung cancer.

Small-cell lung cancer (SCLC) is a refractory cancer with rapid growth and high aggressiveness. Extensive-stage SCLC is initially sensitive to chemotherapy; however, drug resistance and recurrence occur rapidly, resulting in a poor survival outcome due to lack of subsequently efficient therapy. The emergence of immune checkpoint inhibitors (ICIs) generated a new landscape of SCLC treatment and significantly prolonged the survival of patients.

Crosstalk between cancer-associated fibroblasts and non-neuroendocrine tumor cells in small cell lung cancer involves in glycolysis and antigen-presenting features.

Background: Small cell lung cancer (SCLC) is a highly fatal malignancy, the complex tumor microenvironment (TME) is a critical factor affecting SCLC progression. Cancer-associated fibroblasts (CAFs) are crucial components of TME, yet their role in SCLC and the underlying mechanisms during their interaction with SCLC cells remain to be determined.

Methods: Microenvironmental cell components were estimated using transcriptome data from SCLC tissue available in public databases, analyzed with bioinformatic algorithms.

The Mitochondria-Targeted Micelle Inhibits Alzheimer's Disease Progression by Alleviating Neuronal Mitochondrial Dysfunction and Neuroinflammation.

Mitochondrial dysfunction plays an important role in neuroinflammation and cognitive impairment in Alzheimer's disease (AD). Herein, this work designs a mitochondria-targeted micelle CsA-TK-SS-31 (CTS) to block the progression of AD by simultaneously alleviating mitochondrial dysfunction in microglia and neurons. The mitochondria-targeted peptide SS-31 drives cyclosporin A (CsA) to penetrate the blood-brain barrier (BBB) and delivers CsA to mitochondria of microglia and neurons in the brains of 5 × FAD mice.
