Background: The current study evaluates the mortality of 2,354 workers first employed at a Baltimore chromate production plant between 1950 and 1974.
Methods: The National Death Index (NDI Plus) was used to determine vital status and cause of death. Cumulative chromium (VI) exposure and nasal and skin irritation were evaluated as risk factors for lung cancer mortality.
Results: There are 91,186 person-years of observation and 217 lung cancer deaths. Cumulative chromium (VI) exposure, nasal irritation, nasal perforation, nasal ulceration, and other forms of irritation (e.g., skin irritation) were associated with lung cancer mortality.
Conclusion: Cumulative chromium (VI) exposure was a risk factor for lung cancer death. Cancer deaths, other than lung cancer, were not significantly elevated. Irritation may be a possible mechanism for chromium (VI)-induced lung cancer.

Lung cancer is correlated with a high death rate, with approximately 1.8 million mortality cases reported worldwide in 2022. Despite development in the control of lung cancer, most cases are detected at higher stages with short survival rates.

MicroRNA abundance as a particular biomarker for precisely identifying cancer metastases has emerged in recent years. The expression levels of miRNA are analyzed to get insights into cancer tissue detection and subtypes. Similar to other cancer types, the miRNA shows high levels of target mRNA dysregulation in association with non-small cell lung carcinoma (NSCLC).

Photodynamic therapy (PDT) is increasingly regarded as an attractive approach for cancer treatment due to its advantages of low invasiveness, minimal side effects, and high efficiency. Here, two novel Ru(II) complexes , were designed and synthesized by coordinating phenanthroline and biquinoline ligands with Ru(II) center, and their chemo-photodynamic therapy and immunotherapy were explored. Both and exhibited significant phototoxicity against A549 and 4T1 tumor cells type-I/-II PDT.

CD8 T cell exhaustion (Tex) has been widely acknowledged in human cancer, while the underlying mechanisms remain unclear. Here, we demonstrate that reduced amino acid (aa) metabolism and mTOR inactivation are accountable for Tex in human non-small cell lung cancer (NSCLC). NSCLC cells impede the T cell-intrinsic transcription of SLC7A5 and SLC38A1, disrupting aa transport and consequently leading to mTOR inactivation.
