Abstract
Background and aim Lung cancer remains one of the most threatening malignancies, ranking as the second most diagnosed cancer, and it continues to be the leading cause of cancer-related deaths worldwide. Challenges persist with late diagnosis and the high mutational burden characteristic of lung cancer. Methods Our study focuses on identifying the mutational spectrum of a cohort of advanced-stage non-small cell lung cancer (NSCLC) patients using a minimally invasive method through blood collection. To analyze the mutational landscape of these patients, we employed plasma DNA for the next-generation sequencing (NGS) cancer panel Ion Torrent, which contains 50 of the most mutated genes in lung cancer. All protocols for extraction, quality and quantity control, and library preparation follow the manufacturer's rules. Bioinformatics analysis was performed to select pathogenic mutations versus non-pathogenic-benign ones. Results This approach is particularly valuable for patients in advanced stages (III and IV, n=10) of lung adenocarcinoma and lung squamous cell carcinoma, who lack surgical options and limited therapeutic avenues. The comprehensive sequencing analysis revealed that nine of the ten lung cancer patients carried a TP53 mutation. Also, several other mutations exist in various cases, showing heterogeneous profiling. Conclusions Our findings demonstrate the potential of liquid biopsies in providing crucial genetic insights that can guide personalized treatment strategies, improving the management and outcomes for patients with advanced lung cancer.

Abstract
Non-small cell lung cancer (NSCLC) is the most common type of lung cancer and accounts for 85% of lung cancer cases. Aberrant activation of the Signal Transducer and Activator of Transcription 3 (STAT3) is frequently observed in NSCLC and is associated with a poor prognosis. Pre-clinical studies have revealed an unequivocal role for tumor cell-intrinsic and extrinsic STAT3 signaling in NSCLC by promoting angiogenesis, cell survival, cancer cell stemness, drug resistance, and evasion of anti-tumor immunity. Several STAT3-targeting strategies have also been investigated in pre-clinical models, and include preventing upstream receptor/ligand interactions, promoting the degradation of STAT3 mRNA, and interfering with STAT3 DNA binding. In this review, we discuss the molecular and immunological mechanisms by which persistent STAT3 activation promotes NSCLC development, and the utility of STAT3 as a prognostic and predictive biomarker in NSCLC. We also provide a comprehensive update of STAT3-targeting therapies that are currently undergoing clinical evaluation, and discuss the challenges associated with these treatment modalities in human patients.

Abstract
Lung cancer is the leading cancer type of death rate. The lung adenocarcinoma subtype is responsible for almost half of the total lung cancer deaths. Despite the improvements in cancer treatment in recent years, lung adenocarcinoma patients' overall survival rate remains poor. Immunetherapy and chemotherapy are two of the most widely used options for the treatment of cancer. Although many cancer types initially respond to these treatments, the development of resistance is inevitable. The rapid development of drug resistance mainly characterizes lung adenocarcinoma. Despite being the subject of many studies in recent years, the resistance initiation and progression mechanism is still unclear. In this review, we have examined the role of the primary DNA repair pathways (non-homologous end joining (NHEJ) pathway, homologous-recombinant repair (HR) pathway, base excision repair (BER) pathway, and nucleotide excision repair (NER) pathway and transactivation mechanisms of tumor protein 53 (TP53) in drug resistance development. This review suggests that mentioned pathways have essential roles in developing the resistance against chemotherapy and immunotherapy in lung adenocarcinoma patients.

Abstract
Lung cancer is the leading cause of cancer related deaths globally, making it a major health concern. The lung’s permissive rich microenvironment is ideal for supporting outgrowth of disseminated tumors from pre-existing extra-pulmonary malignancies usually resulting in high mortality. Tumors occurring in the lungs are difficult to treat, necessitating the need for the development of advanced treatment modalities against primary tumors and secondary lung metastasis. In this review, we explore the pulmonary route as an attractive drug delivery approach to treat lung tumors. We also discuss the potential of pulmonary delivery of cancer vaccine vectors to induce mucosal immunity capable of preventing the seeding of tumors in the lung.

Abstract
Resistance to chemotherapy is a major problem facing current cancer therapy, which is continuously aiming at the development of new compounds that are capable of tackling tumors that developed resistance toward common chemotherapeutic agents, such as doxorubicin (DOX). Alongside the development of new generations of compounds, nanotechnology-based delivery strategies can significantly improve the in vivo drug stability and target specificity for overcoming drug resistance. In this study, multifunctional gold nanoparticles (AuNP) have been used as a nanoplatform for the targeted delivery of an original anticancer agent, a Zn(II) coordination compound [Zn(DION)2]Cl2 (ZnD), toward better efficacy against DOX-resistant colorectal carcinoma cells (HCT116 DR). Selective delivery of the ZnD nanosystem to cancer cells was achieved by active targeting via cetuximab, NanoZnD, which significantly inhibited cell proliferation and triggered the death of resistant tumor cells, thus improving efficacy. In vivo studies in a colorectal DOX-resistant model corroborated the capability of NanoZnD for the selective targeting of cancer cells, leading to a reduction of tumor growth without systemic toxicity. This approach highlights the potential of gold nanoformulations for the targeting of drug-resistant cancer cells.

Abstract
Systemic chemotherapy has remained the traditional treatment for metastatic non-small-cell lung carcinoma (NSCLC), enhancing survival rate at 1 year to 29%. The median survival had plateaued at around 10 months until early 2008, and in an attempt to enhance survival in advanced disease, maintenance chemotherapy trials were initiated which had recently demonstrated prolongation of survival by an additional 2-3 months in patients who had performance status (PS) 0-1 and well-preserved organ functions. Suitable patients with any degree of clinical benefit are treated with 4-6 cycles, and then one of the active agents is continued until best response, or toxicity (continued maintenance), or changed to a cross non-resistant single agent (switch maintenance). The article briefly reviews the evolution of systemic therapy and describes key randomised trials of maintenance therapy instituting chemotherapy and targeted agents in an attempt to improve outcomes in advanced metastatic NSCLC, based on certain clinical features, histology, and genetics.

Abstract
OBJECTIVE To observe the efficacy of the inhalation of an aerosolized group A streptococcal (GAS) preparation in treating orthotopic lung cancer in mouse models and assess the feasibility, safety, and effectiveness of this administration mode for lung cancer. METHODS Lewis lung carcinoma (LLC) cell strains were administered via intrathoracic injection to establish orthotopic lung cancer mouse models. After the tumor-bearing models were successfully established, as confirmed by computed tomography, the mice were administered by inhalation with an aerosolized GAS preparation (GAS group) or aerosolized normal saline (control group). The anti-tumor effect of the aerosolized GAS preparation was evaluated histologically; meanwhile, the survival and quality of life were compared between these two groups. RESULTS The aerosolized GAS preparation showed remarkably anti-tumor effect, causing the necrosis of the orthotopic lung cancer cells in tumor-bearing mice. Furthermore, mice in the GAS group had significantly better quality of life and longer survival than those in control group. CONCLUSIONS The inhalation of aerosolized GAS preparation may be a feasible, safe and effective solution for lung cancer.

Abstract
The purposes of this study were to investigate the role of Aplysia Ras Homolog I (ARHI) on cell growth, proliferation, apoptosis, and other biological characteristics of HER2-positive breast cancer cells. Our goal was to provide experimental evidence for the development of future effective treatments of HER2-positive breast cancer. A pcDNA3.1-ARHI eukaryotic expression vector was constructed and transfected into the human HER2-positive breast cancer cell lines SK-BR-3 and JIMT-1. Then, various experimental methods were utilized to analyze the biological characteristics of ARHI-expressing breast cancer cells and to examine the impact of expression of the ARHI gene on cyclin D1, p27(Kip1), and calpain1 expression. We further analyzed the cells in each group after treatment with trastuzumab to examine the effects of this drug on various cellular characteristics. When we compared pcDNA3.1-ARHI-expressing SK-BR-3 and JIMT-1 cells to their respective empty vector and control groups, we found that cell viability was significantly lower (p < 0.05) in the ARHI-expressing cells, and the proportions of G1 phase cells and apoptotic cells were significantly higher in the ARHI-expressing cells (p < 0.05). In all groups of SK-BR-3 cells, trastuzumab treatment significantly decreased cell growth (p < 0.05). The proportion of cells in G1 phase and the number of apoptotic cells in the pcDNA3.1-ARHI-expressing group were significantly higher than that in the empty vector group and the control group (p < 0.05). The growth of pcDNA3.1-ARHI-transfected JIMT-1 cells was significantly decreased (p < 0.05), while the proportion of apoptotic cells was significantly increased (p < 0.05). Cell growth, viability, and the percentage of apoptotic cells were similar between the JIMT-1 empty vector and control groups. ARHI expression inhibited cyclin D1 expression in SK-BR-3 cells and JIMT-1 cells, while it promoted p27(Kip1) and calpain1 expression in these cells. ARHI expression inhibits the growth and proliferation of HER2-positive breast cancer cells, while it also promotes apoptosis in these cells. ARHI expression also improves the sensitivity of JIMT-1 cells to trastuzumab by inducing apoptosis.
