From the perspective of circular economy, it is extremely useful to recycle waste products for human health applications. Among health-beneficial properties bioactive phyto-compounds, grape pomace represents a precious source molecules with potential antitumor properties. Here, we describe effects Sicilian hydroalcoholic extract (HE) in colon and breast cancer cells. The characterization HE composition revealed predominance anthoxanthins phenolic acids. treatment was more effective reducing viability cells, while cells appeared resistant. Indeed, underwent apoptosis, as shown by DNA fragmentation, caspase-3 activation, PARP1 degradation, seemed not undergo apoptosis. To elucidate underlying mechanisms, reactive oxygen species (ROS) were evaluated. Interestingly, ROS increased both cell lines but, cancer, cells' rapidly progressively diminished over time, increase persistent up 24 h. This effect correlated induction pro-survival autophagy, demonstrated autophagosomes formation, autophagic markers increase, protection antioxidant NAC. autophagy inhibitor bafilomycin A1 significantly but Overall, our data provide evidence that efficacy tumor depends on balance between ROS-mediated Therefore, inhibiting may be tool target those appear resistant HE.

Chemo-dynamic therapy (CDT) based on the Fenton or Fenton-like reaction has emerged as a promising approach for cancer treatment. However, autophagy-mediated self-protection mechanisms of cells pose significant challenge to efficacy CDT. Herein, we developed metal-DNA nanocomplexes (DACs-Mn) enhance CDT via DNAzyme inhibition autophagy. Specifically, Mn-based catalyst in DACs-Mn was used generate highly hydroxyl radicals (⋅OH) that kill cells, while ATG5 incorporated into inhibited expression autophagy-associated proteins, thereby improving By disrupting self-protective pathway under severe oxidative stress, this novel found synergistically both vitro and vivo models, effectively amplifying tumor-specific damage. Notably, Metal-DNA can also induce immunogenic cell death (ICD), inhibiting tumor metastasis. bilateral model mice, combined autophagy followed by immune checkpoint blockade shown potential effective treatment modality primary metastatic tumors.

Autophagy is a fundamental homeostatic process in which certain cellular components are ingested by double-membrane autophagosomes and then degraded to create energy or maintain homeostasis survival. It typically observed nutrient-deprived cells as survival mechanism. However, it has also been identified crucial maintaining disease progression. Normal metabolism produces reactive oxygen (ROS) nitrogen species at low levels. increased production causes oxidative stress, can lead diabetes, cardiovascular diseases, neurological disorders, cancer. was recently shown that redox equilibrium via autophagy critical for responses stress. little understood about the molecular cancer processes connect control of autophagy. In cells, oncogenic mutations, carcinogens, metabolic reprogramming cause ROS generation Recent studies have suggested activates pathways promote development metastasis. Moreover, relationship between programming involved malignant phenotype.

Autophagy is a fundamental cellular process that maintains homeostasis by degrading damaged components and regulating stress responses. It plays crucial role in cancer biology, including tumor progression, metastasis, therapeutic resistance. Oxidative stress, similarly, key to maintaining balance oxidants antioxidants, with its disruption leading molecular damage. The interplay between autophagy oxidative particularly significant, as reactive oxygen species (ROS) act both inducers by-products of autophagy. While can function suppressor early stages, it often shifts pro-tumorigenic advanced disease, aiding cell survival under adverse conditions such hypoxia nutrient deprivation. This dual mediated several signaling pathways, PI3K/AKT/mTOR, AMPK, HIF-1α, which coordinate the autophagic activity ROS production. In this review, we explore mechanisms interact across different hematological malignancies. We discuss how triggers autophagy, creating feedback loop promotes survival, dysregulation leads increased accumulation, exacerbating tumorigenesis. also examine implications targeting autophagy-oxidative axis cancer. Current strategies involve modulating through specific inhibitors, enhancing levels pro-oxidant compounds, combining these approaches conventional therapies overcome drug Understanding complex relationship provides critical insights into novel aimed at improving treatment outcomes.
