Despite significant advancements in the oncology field, lung cancer remains the leading cause of cancer‐related mortality worldwide. A key contributor to the increased mortality rate is the resistance exhibited by cancer cells to standard anticancer treatments, particularly in advanced stages of the disease. Evidence indicates that chronic inflammation within the tumour microenvironment (TME) promotes tumorigenesis and contributes to resistance to immunotherapy, radiotherapy and chemotherapy. Notably, the overexpression of the cytokine interleukin‐6 (IL‐6) has been documented in various tumours, including lung cancer. Both tumour‐associated fibroblasts (TAFs) and tumour cells constitute the predominant sources of secreted IL‐6 within the TME. Various research has elucidated the role of IL‐6 and its signalling pathways in facilitating therapeutic resistance, metastasis and tumour progression in lung cancer. Consequently, targeting IL‐6 and/or its receptor, in conjunction with other effective anticancer treatments, represents an ideal therapeutic technique for lung cancer management. This review aims to synthesize recent evidence on the function of the IL‐6/IL‐6R signalling pathway in lung cancer, with a focus on its role in therapy resistance, prognosis and tumour progression, on the basis of clinical and preclinical studies.

Annual oil spills of diverse scales pose distinct challenges to Freshwater Habitats. The intricate and variable characteristics of oil render standardized risk evaluation challenging. Examining the scientific landscape concerning oil's distinct difficulty, the biological effects of oil spills, and the application of rapid evaluation tools, such as commercial toxicity kits and tests, enables us to investigate the prevailing challenges hindering efficient and prompt risk evaluation of oils. Although monitoring programs benefit from well-validated standardized tests that examine impacts throughout different trophic levels at environmentally pertinent levels, a minimal proportion of the available tests are specifically designed for marine ecosystems or verified for assessing crude oil toxicity. The research discusses the application of fast testing at low trophic stages with pertinent sublethal toxicity tests to facilitate the characterization of the lethality of oil, dispersants, and their mixtures. The research recognizes innovative, passively dosing methods as an effective and consistent approach to enhancing the precision and stability of nominal doses. Subsequent research should investigate the potential integration of this tiered testing method with models of ecosystems to facilitate the forecast and risk evaluation of the Freshwater Habitats.

Many pesticides are no longer effective against insect populations due to development of resistance in insects against them insects so mostly acquire resistance to pesticides by means of metabolic tolerance and target-site modifications. Breaking down dangerous compounds and rendering them harmless depends much on enzymes such cytochrome P450 monooxygenases, glutathione S-transferases (GSTs), and esterases. Target protein changes such as acetylcholinesterase alter where they bind, therefore reducing the efficacy of herbicides. Furthermore shown by this research are epigenetic modifications such DNA methylation and histone modifications that assist regulate detoxification genes, therefore strengthening the body’s resistance. Growing frequency of cross-resistance and multi-resistance patterns makes it increasingly difficult to eradicate insects.
