Exemplified by successful use in COVID-19 vaccination, delivery of modified mRNA encapsulated in lipid nanoparticles provides a framework for treating various genetic and acquired disorders. However, lipid nanoparticles that can deliver mRNA into specific lung cell types have not yet been established. Here, we sought whether poly(®-amino ester)s (PBAE) or PEGylated PBAE (PBAE-PEG) in combination with 4A3-SC8/DOPE/cholesterol/DOTAP lipid nanoparticles (LNP) could deliver mRNA into different types of lung cells in vivo.

Comb Chem High Throughput Screen
January 2025
Biomedical Sciences College & Shandong Medicinal Biotechnology Centre, Shandong First Medical University & Shandong Academy of Medical Sciences, Jinan, China.
Objective: This study aimed to investigate the effect of angelicin on the NSCLC tumor growth.
Background: Accumulating evidence shows that cancer-associated fibroblasts (CAFs) play an important role in tumor progression and metastasis, making CAFs an increasingly attractive target for therapeutic intervention. Targeted therapies against CAFs have been considered to have the potential to significantly improve cancer treatment outcomes, overcome resistance, and improve immune evasion.
Diagnostic value of interferon-γ release assay in patients with COPD complicated with pulmonary tuberculosis.
BMC Infect Dis
January 2025
The Third Department of Infection, Fifth Hospital of Shijiazhuang, Shijiazhuang, Hebei, China.
Background: The common diagnostic methods for tuberculosis have been showing reduced sensitivity among chronic obstructive pulmonary disease patients. This study was conducted to evaluate and analyse the diagnostic value of an interferon-γ release assay in COPD patients complicated with pulmonary tuberculosis.
Methods: A nested case-control study was conducted on 123 COPD patients hospitalized at the Fifth Hospital of Shijiazhuang, Hebei Province, from January 2019 to June 2021.
Background: Identifying the underlying mechanisms of immune checkpoint inhibitor resistance in patients with cachexia is a current challenge. Ghrelin is a peptide hormone that plays an important role in the metabolism of patients with cancer cachexia. Despite the importance of ghrelin in cancer cachexia, most previous studies on the subject have not distinguished between the forms of ghrelin.

Clin Cancer Res
January 2025
Moffitt Cancer Center, Tampa, Florida, United States.
Purpose: Therapeutic efficacy of KRASG12C(OFF) inhibitors (KRASG12Ci) in KRASG12C-mutant non-small cell lung cancer (NSCLC) varies widely. The activation status of RAS signaling in tumors with KRASG12C mutation remains unclear, as its ability to cycle between the active GTP-bound and inactive GDP-bound states may influence downstream pathway activation and therapeutic responses. We hypothesized that the interaction between RAS and its downstream effector RAF in tumors may serve as indicators of RAS activity, rendering NSCLC tumors with a high degree of RAS engagement and downstream effects more responsive to KRASG12Ci compared to tumors with lower RAS---RAF interaction.
