Article Abstract
Gliomas are the most common lethal tumors of the brain associated with a poor prognosis and increased resistance to chemo-radiotherapy. Circular RNAs (circRNAs), newly identified noncoding RNAs, have appeared as critical regulators of therapeutic resistance among multiple cancers and gliomas. Since circRNAs are aberrantly expressed in glioma and may act as promoters or inhibitors of therapeutic resistance, we categorized alterations of these specific RNAs expression in therapy resistant-glioma in three different classes, including chemoresistance, radioresistance, and glioma stem cell (GSC)-regulation. circRNAs act as competing endogenous RNA, sponging target microRNA and consequently affecting the expression of genes related to glioma tumorigenesis and resistance. By doing so, circRNAs can modulate the critical cellular pathways and processes regulating glioma resistance, including DNA repair pathways, GSC, epithelial-mesenchymal transition, apoptosis, and autophagy. Considering the poor survival and increased resistance to currently approved treatments for glioma, it is crucial to increase the knowledge of the resistance regulatory effects of circRNAs and their underlying molecular mechanisms. Herein, we conducted a comprehensive search and discussed the existing knowledge regarding the important role eof circRNAs in the emergence of resistance to therapeutic interventions in glioma. This knowledge may serve as a basis for enhancing the effectiveness of glioma therapeutic strategies.

Ferroptosis, a controlled cell death influenced by iron-dependent lipid peroxidation, presents potential therapeutic targets for cancer treatment due to its unique molecular pathways and potential drug resistance. Natural compounds, such as polyphenols, flavonoids, terpenoids and alkaloids, can influence ferroptosis via important signalling pathways, such as Nrf2/Keap1, p53, and GPX4. These are promising for combinational therapy due to their ability to cause ferroptotic death in cancer cells, exhibit tumour-specific selectivity and reduce systemic toxicity.

The overreliance on traditional chemical fungicides, combined with the emergence of resistance, poses significant challenges for food safety. Early blight, caused by the fungal pathogen Alternaria solani (A. solani), is among the most significant contributors to pre- and postharvest yield losses in tomato cultivation.

With upfront use of triplet- and quadruplet-based regimens coupled with autologous stem cell transplant (ASCT) and maintenance lenalidomide, a high proportion of multiple myeloma (MM) patients are achieving deep and durable responses. Yet, myeloma invariably relapses, with refractoriness to one or more drugs at first relapse. This therapeutic gap has been partially filled by T-cell engager (TCE) therapies that have demonstrated remarkable response rates and prolonged remissions in heavily pretreated patients with MM, providing off-the-shelf immunotherapy options leading to the U.

Mutations in the KRAS gene are prominent oncogenic drivers in non-small cell lung cancer (NSCLC), with multiple pathophysiological, clinical and prognostic implications. Although historically considered an "undruggable" target, recent research led to the development of specific KRAS-G12C inhibitors, like sotorasib and adagrasib which are currently approved for clinical use in patients affected by advanced NSCLC. However, the clinical utility of these drugs is often limited by resistance development through several biological mechanisms, including additional KRAS mutations, activation of compensatory pathways and metabolic reprogramming.

Platinum-group metal half-sandwich complexes are considered to be potential replacements of the clinically widely used platins which have several side effects and tend to cause resistance to develop. In our previous works, we used a range of 2-pyridyl-substituted N- and C-glycosyl heterocycles as N,N-chelating ligands to prepare ruthenium(II), osmium(II), iridium(III) and rhodium(III) polyhapto arene/arenyl half-sandwich complexes. Some of these complexes, particularly with the C-glucopyranosyl isoxazole derived ligand in its O-perbenzoylated form, exhibited greater anticancer efficiency than cisplatin and had minimal or negligible effects on non-transformed fibroblasts.
