This article provides a systematic review of the research progress in the mechanisms related to lung cancer and ferroptosis, ferroptosis-related lung cancer biomarkers and gene mutation targets, and ferroptosis-targeted regulation of Chinese medicine in treating lung cancer in the past five years, providing a feasible and effective basis for the prevention and treatment of lung cancer with Chinese medicine and the development of new drugs. According to the available studies, ferroptosis is widely suppressed in lung cancer, while the specific regulatory mechanisms have not been fully elucidated. The suppression is related to lipid metabolism, iron metabolism, cystine/glutamate antiporter system Xc- (System Xc-)/glutathione (GSH)/glutathione peroxidase 4 (GPX4), ferroptosis suppressor protein 1 (FSP1)/coenzyme Q10 (CoQ10)/nicotinamide adenine dinucleotide phosphate [NAD(P)H], long non-coding RNA (lncRNA), nuclear factor E2-related factor 2 (Nrf2), and p53. In modern times, traditional Chinese medicine is widely used in the comprehensive treatment of lung cancer, and it has gradually become a hot research topic due to its obvious advantages of anti-tumor activity, high efficacy, and low toxicity. Traditional Chinese medicine plays an important role in the treatment of lung cancer. Studies have shown that the active components, extracts, and prescriptions of Chinese medicine can induce ferroptosis in lung cancer cells through targeted regulation of iron metabolism, lipid metabolism, and p53, Nrf2, LncRNA, and GPX4 pathways to inhibit the growth and proliferation of lung cancer, thus exerting anti-tumor effects. Therefore, regulating ferroptosis is expected to become a new direction for preventing lung cancer. Basic research has shown that Chinese medicine can regulate ferroptosis via multiple targets and pathways in the treatment of lung cancer. At present, Chinese medicine demonstrates great research prospects in regulating ferroptosis to treat lung cancer, which, howeve, still faces challenges to achieve clinical transformation.

Objective :
To investigate the effects and mechanism of small ubiquitin-like modifier ( SUMO) specific proteinase-1 (SENP-1) on chronic intermittent hypoxia ( CIH) induced myocardial injury in rats.
Methods :
32 male SD rats were randomly divided into : control group,CIH group,negative control adeno-associated virus interven- tion group (AAV-shNC) and SENP-1 shRNA adeno-associated virus intervention group (AAV-shSENP-1) ,with 8 rats in each group.After 6 weeks of CIH induction,echocardiography was performed.The levels of cardiac troponin I (cTNI) ,creatine kinase MB isoenzyme ( CKMB) ,myoglobin (Mb) ,lactate dehydrogenase (LDH) in serum and malondialdehyde (MDA) ,uperoxide dismutases ( SOD) ,glutathione ( GSH) ,interleukin( IL) -1 β , IL-6 and tumor necrosis factor-α(TNF-α) in myocardial tissue were detected by ELISA.The pathological changes of myocardial tis- sue was observed by HE staining.The reactive oxygen species ( ROS) level in myocardial tissue was detected by DCFH-DA fluorescence probe labeling.The small ubiquitin-like modifier (SUMO) level of hypoxia inducible factor- 1 α (HIF-1 α) protein in myocardial tissue was detected by kit.The mRNA and protein levels of SENP-1 and HIF- 1 α in myocardial tissue were detected by qRT-PCR and Western blot.
Results :
Compared with the control group, the pathological damage of myocardial tissue in CIH group was serious,the levels of left ventricular end diastolic diameter (LVEDD) ,left ventricular end systolic dimension (LVESD) and serum cTNI,CKMB,Mb and LDH signif- icantly increased (P<0. 05) ,and the levels of ROS,MDA,IL-1 β , IL-6,TNF-α and the mRNA and protein levels of SENP-1 and HIF-1α in myocardial tissue also significantly increased (P <0. 05 ) ,while the levels of LVEF, LVFS,serum GSH and SOD significantly decreased (P <0. 05) ,and the SUMOylates level of HIF-1α protein in myocardial tissue also significantly decreased (P <0. 05 ) .Compared with CIH group,AAV-shSENP-1 group had less myocardial pathological damage,the levels of LVEDD,LVESD and serum cTNI,CKMB,Mb and LDH signifi- cantly decreased (P<0. 05) ,and the levels of ROS,MDA,IL-1 β, IL-6,TNF-α and the mRNA and protein levels of SENP-1 and HIF-1α in myocardial tissue also significantly decreased (P<0. 05) ,the levels of LVEF,LVFS,serum GSH and SOD significantly increased (P<0. 05) ,and the SUMOylates level of HIF-1α protein in myocardial tissue also significantly decreased (P<0. 05) .
Conclusion
Inhibition of SENP-1 expression can alleviate CIH induced myocarditis and oxidative stress in rats,improve myocardial injury and cardiac dysfunction,and its mechanism may be related to the improvement of HIF-1α SUMOylates level,thus inhibiting HIF-1α expression.
