Current and future therapeutic approaches of CFTR and airway dysbiosis in an era of personalized medicine.

Cystic fibrosis (CF) is a life-threatening genetic disorder caused by mutations in the CFTR gene. This leads to a defective protein that impairs chloride transport, resulting in thick mucus buildup and chronic inflammation in the airways. The review discusses current and future therapeutic approaches for CFTR dysfunction and airway dysbiosis in the era of personalized medicine.

Expert panel opinion on adult pneumococcal vaccination in the post-COVID era (NAP- EXPO Recommendations-2024).

SOX9 as an emerging target for anticancer drugs and a prognostic biomarker for cancer drug resistance.

The dysregulated expression of the transcription factor (TF) Sry-related HMG box 9 (SOX9) has been extensively correlated with various biological effects, including the initiation and progression of cancer. Differential expression of SOX9 has been positively correlated with cancer cell growth, invasion, migration, metastasis, and therapy resistance. Studies showed that expression of SOX9 affects the expression of various miRNAs and vice versa, resulting in the development of cancer drug resistance.

Phytomedicines Targeting Cancer Stem Cells: Therapeutic Opportunities and Prospects for Pharmaceutical Development.

The presence of small subpopulations of cells within tumor cells are known as cancer stem cells (CSCs). These cells have been the reason for metastasis, resistance with chemotherapy or radiotherapy, and tumor relapse in several types of cancers. CSCs underwent to epithelial-mesenchymal transition (EMT) and resulted in the development of aggressive tumors.

SOX9 promotes epidermal growth factor receptor-tyrosine kinase inhibitor resistance via targeting β-catenin and epithelial to mesenchymal transition in lung cancer.

Aims: The first-generation epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI), gefitinib, continues to be a primary treatment option for lung cancer patients. However, acquisition of resistance to gefitinib is a major obstacle in lung cancer treatment and its cause is poorly understood. The present study aimed to implicate the role of SOX9-β-catenin in developed resistance to gefitinib through epithelial to mesenchymal transition (EMT) in lung cancer in vitro and ex vivo.

Kirsten rat sarcoma virus protein overexpression in adenocarcinoma lung: Association with clinicopathological and histomorphological features.

Context: Lung cancer is the leading cause of cancer-related deaths worldwide. The constitutive activation of multiple signaling pathways is the major cause of carcinogenesis.

Allosteric mutant-selective fourth-generation EGFR inhibitors as an efficient combination therapeutic in the treatment of non-small cell lung carcinoma.

Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) show most preferable treatment for non-small cell lung carcinoma (NSCLC) with EGFR activating mutations. Despite initial impressive response of first-, to third-generation EGFR-TKIs, these agents become ineffective because of rapid emergence of EGFR mutations (T790M or C797S) mediated resistance. Allosteric mutant-selective fourth-generation EGFR inhibitors appeared to be possible therapeutic option to overcome resistance.

SOX9: An emerging driving factor from cancer progression to drug resistance.

Dysregulation of transcription factors is one of the common problems in the pathogenesis of human cancer. Among them, SOX9 is one of the critical transcription factors involved in various diseases, including cancer. The expression of SOX9 is regulated by microRNAs (miRNAs), methylation, phosphorylation, and acetylation.

Recent updates on the resistance mechanisms to epidermal growth factor receptor tyrosine kinase inhibitors and resistance reversion strategies in lung cancer.

Epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) have led to a substantial improvement in the prognosis of lung cancer patients by explicitly targeting the activating mutations within the EGFR. Initially, patients harboring tumors with EGFR mutations show progression-free survival and improvement in the response rates toward all-generation EGFR-TKIs; however, these agents fail to deliver the intended results in the long-term due to drug resistance. Therefore, it is necessary to recognize specific cardinal mechanisms that regulate the resistance phenomenon.
