Berberine induces dose-dependent quiescence and apoptosis in A549 cancer cells by modulating cell cyclins and inflammation independent of mTOR pathway

The alkaloid berberine is recognized for its anti-cancer attributes but its potential to induce senescence in tumour cells is least understood.Materials and methodsThe present work assessed the mechanisms pertaining to dose-dependent anti-proliferative effects of berberine in the perspective of senescence and inflammation using human non-small cell lung cancer cell line (A549).Key findingsAmongst the different tested bioactive phytomolecules, berberine treatment suppressed the proliferation of A549 cells regardless of the concentration applied. Application of low doses of berberine induced a weak SA-β-gal activity and p21WAF1 expression but did not show evidence of SASP activation due to absence of NF-κB activation and expression of proinflammatory genes. However, treatment with higher dose of berberine showed no evidence of SA-β-gal activity or p21WAF1 expression, but instead induced apoptosis and suppressed the expression of cell cyclins. The proliferative capacity of berberine treated cells was at par with control cells and no SA-β-gal activity could be observed in first generation of berberine treated cells. mTO...

Authors: Han AR, Lee S, Han S, Lee YJ, Kim JB, Seo EK, Jung CH Abstract Radiotherapy using ionizing radiation is a major therapeutic modality for advanced human lung cancers. However, ionizing radiation itself can induce malignant behaviors such as cancer cell migration and invasion, leading to local recurrence or distal metastasis. Therefore, safer and more effective agents that inhibit the metastatic behaviors of cancer cells in radiotherapy are needed. As a part of our ongoing search for new radiotherapy enhancers from medicinal herbs, we isolated the following triterpenoids from the ethanol extract of Centella ...

CONCLUSIONS: Aaptamine retarded the proliferation and invasion of NSCLC cells by selectively targeting the pathway PI3K/AKT/GSK3β suggesting it as a potential chemotherapeutic agent for repressing tumorigenesis and progression of NSCLC in humans. PMID: 33027592 [PubMed - in process]
Conclusion: As far as we know, this study will be the first meta-analysis to compare the efficacy of the vein-first and artery-first surgical technique of segmentectomy for patients diagnosed with resectable non–small cell lung cancer. Due to the nature of the disease and intervention methods, RCTs may be inadequate, and we will carefully consider inclusion in high-quality, non-RCTs, but this may result in high heterogeneity and affect the reliability of the results.

Rationale: Anlotinib has been proved to be effective in advanced refractory non-small cell lung cancer. Patient concerns: A 47-year-old female non-smoker was admitted due to persistent chest tightness for a month. Diagnoses: Epidermal growth factor receptor (EGFR) wild-type advanced primary lung adenocarcinoma without brain or bone metastasis. Interventions: The patient failed 2 lines of pemetrexed/docetaxel plus carboplatin and third-line erlotinib. Fourth-line anlotinib was administered thereafter. Outcomes: The pulmonary lesions showed partial remission 5 months after anlotinib monotherapy. The patient dem...
ConclusionIn proton-based 4D Robust SBRT, the interplay effects degraded the target dose distribution but were mitigated using iso-energy layer repainting techniques. However, there was no significant correlation between the number of repainting layers and improvements in the dose distributions. The optimal layer repainting times based on the interplay effect index were ascertained according to the patient characteristics.
