IGFBP2/ITGA5 promotes gefitinib resistance via activating STAT3/CXCL1 axis in non-small cell lung cancer.

There is a paucity of comprehensive knowledge pertaining to the underlying mechanisms leading to gefitinib resistance in individuals diagnosed NSCLC harboring EGFR-sensitive mutations who inevitably develop resistance to gefitinib treatment within six months to one year. In our preceding investigations, we have noted a marked upregulation of IGFBP2 in the neoplastic tissues of NSCLC, predominantly in the periphery of the tissue, implying its plausible significance in NSCLC. Consequently, in the current research, we delved into the matter and ascertained the molecular mechanisms that underlie the participation of IGFBP2 in the emergence of gefitinib resistance in NSCLC cells.

A novel anti-CD47 protein antibody and toll-like receptor agonist complex detects tumor surface CD-47 changes in early stage lung cancer by in vivo imaging.

CD47, a cell surface protein known for inhibiting phagocytosis, plays a critical role in the tumor microenvironment (TME) and is a potential biomarker for cancer. However, directly applying αCD47, a hydrophilic macromolecular antibody that targets CD47, in vivo for cancer detection can have adverse effects on normal cells, cause systemic toxicities, and lead to resistance against anti-cancer therapies. In this study, we developed a novel complex incorporating aluminum-based metal-organic frameworks (Al-MOF) loaded with indocyanine green (ICG), αCD47, and resiquimod (R848), a hydrophobic small molecule Toll-like receptor 7/8 (TLR7/8) agonist.

[Current Situation and Future Direction of Multidisciplinary Diagnosis and Treatment of Lung Cancer].

Although multidisciplinary team (MDT) diagnosis and treatment model can improve the quality of life and survival prognosis of the patients, why does it not reach the expected goal of the MDT diagnosis and treatment model? The main reason is that the diagnosis and treatment mode of MDT in lung cancer lags behind the progress of various treatment methods. By analyzing the latest research results of MDT diagnosis and treatment of lung cancer at home and abroad, combined with the experience of MDT diagnosis and treatment of lung cancer in the Lung Cancer Center of West China Hospital of Sichuan University, this article will discuss and summarize the progress and future direction of MDT in lung cancer from the following aspects: (1) The connotation and extension of MDT diagnosis and treatment mode of lung cancer need to be changed and adapted to new methods of diagnosis and treatment; (2) The clinical decision making in the diagnosis and treatment of MDT in lung cancer should be transformed from "multidisciplinary consultation (MDC)" to "MDT"; (3) The diagnosis and treatment process of MDT in lung cancer should shift from "fire brigade mode" to "firewall mode", and finally implement "individualized whole-process management mode"; (4) The path of MDT diagnosis and treatment of lung cancer should be changed from "temporary convening mode" to "single disease center system mode of lung cancer".

Efficacy of first-line dual oral pyrotinib plus capetabine therapy in HER2-positive metastatic breast cancer: A real-world retrospective study.

Background: The combination of dual-targeted human epidermal growth factor receptor 2 (HER2) therapy and chemotherapy is the standard first-line regimen for recurrent/metastatic breast cancer (mBC). However, the toxicity of such combination therapy can lead to some patients being unable to tolerate adverse events or bear treatment costs. As a novel irreversible pan-ErbB receptor TKI (pyrotinib), can the dual oral administration of pyrotinib plus capetabine (PyroC) provide first-line survival benefits and serve as a more affordable treatment option?

Methods: This real-world retrospective study included patients diagnosed with HER2-positive mBC who received PyroC as a first-line treatment at West China Hospital between May 2018 and July 2023.

FOXA3 regulates cholesterol metabolism to compensate for low uptake during the progression of lung adenocarcinoma.

Cholesterol metabolism is vital for multiple cancer progression, while how cholesterol affects lung, a low-cholesterol tissue, for cancer metastasis and the underlying mechanism remain unclear. In this study, we found that metastatic lung adenocarcinoma cells acquire cellular dehydrocholesterol and cholesterol by endogenous cholesterol biosynthesis, instead of uptake upon cholesterol treatment. Besides, we demonstrated that exogenous cholesterol functions as signaling molecule to induce FOXA3, a key transcription factor for lipid metabolism via GLI2.
