Lung cancer, one of the most frequently diagnosed cancers, causes a huge number of mortalities globally. Among lung cancers, non-small cell lung cancer (NSCLC) is the most recorded. Despite accumulating research, the molecular basis of NSCLC progression remains poorly known. Therefore, we aim to assess the function of NCK1-AS1 in NSCLC and elucidate the molecular mechanism. Firstly, we quantified the NCK1-AS1 level in tumors and adjacent healthy tissues. NCK1-AS1 was significantly upregulated in NSCLC tumors, which was associated with poor prognosis in patients. Silencing NCK1-AS1 significantly inhibited the proliferation, migration, and invasion, as well as the EMT of NSCLC cell lines. Starbase bioinformatic prediction revealed that NCK1-AS1 targets miR-361-5p which acts to regulate ADAM10 gene expression. Our result showed that NCK1-AS1 upregulation markedly reduced miR-361-5p mRNA expression, while increasing ADAM10 expression. For the first time, we demonstrated that NCK1-AS1 regulates the miR-361-5p/ADAM10 axis, thereby promoting NSCLC progression. NCK1-AS1 might be developed as a therapeutic target for treating NSCLC.

Coronavirus disease 2019 (COVID-19) still causes death in elderly and immunocompromised individuals, for whom the sustainability of the vaccine response may be limited. Antiviral treatments, such as remdesivir or molnupiravir, have demonstrated limited clinical efficacy. Nirmatrelvir, an acute respiratory syndrome coronavirus 2 (SARS-CoV-2) major protease inhibitor, is clinically effective but has been associated with viral rebound and antiviral resistance.

However, the optimal strategy to combine EGFR tyrosine kinase inhibitors (TKIs) with radiotherapy for maximum efficacy and minimal toxicity is still uncertain. Notably, EVs, which serve as communication mediators among tumor cells, play a crucial role in the anti-tumor immune response.

Non-small cell lung cancer (NSCLC) is the predominant form of lung cancer and poses a significant public health challenge. Early detection is crucial for improving patient outcomes, with serum biomarkers such as carcinoembryonic antigen (CEA), squamous cell carcinoma antigen (SCCAg), and cytokeratin fragment 19 (CYFRA 21-1) playing a critical role in early screening and pathological classification of NSCLC. However, due to being mainly based on corresponding antibody binding reactions, existing detection technologies for these serum biomarkers have shortcomings such as complex operations, high false positive rates, and high costs.

Here, we report on the synthesis and biological evaluation of a novel peptide-drug conjugate, P6-SN38, which consists of the EGFR-specific short cyclic peptide, P6, and the Topo I inhibitor SN38, which is a bioactive metabolite of the anticancer drug irinotecan. SN38 is attached to the peptide at position 20 of the E ring's tertiary hydroxyl group via a mono-succinate linker. The developed peptide-drug conjugate (PDC) exhibited sub-micromolar anticancer activity on EGFR-positive (EGFR+) cell lines but no effect on EGFR-negative (EGFR-) cells.
