Abstract Ferroptosis, an iron-dependent form of cell death characterized by uncontrolled lipid peroxidation, is governed molecular networks involving diverse molecules and organelles. Since its recognition as a non-apoptotic pathway in 2012, ferroptosis has emerged crucial mechanism numerous physiological pathological contexts, leading to significant therapeutic advancements across wide range diseases. This review summarizes the fundamental mechanisms regulatory pathways underlying ferroptosis, including both GPX4-dependent -independent antioxidant mechanisms. Additionally, we examine involvement various conditions, cancer, neurodegenerative diseases, sepsis, ischemia–reperfusion injury, autoimmune disorders, metabolic disorders. Specifically, explore role response chemotherapy, radiotherapy, immunotherapy, nanotherapy, targeted therapy. Furthermore, discuss pharmacological strategies for modulating potential biomarkers monitoring this process. Lastly, elucidate interplay between other forms regulated death. Such insights hold promise advancing our understanding context human health disease.

Cold atmospheric plasma (CAP) has exhibited exciting potential for cancer treatment. Reactive oxygen and nitrogen species (RONS), the primary constituents in CAP, contribute to cell death by elevating oxidative stress cells. However, several intrinsic cellular antioxidant defense systems exist, such as glutathione peroxidase 4 (GPX4) enzyme, which dampens cell-killing efficacy of CAP. RAS-selective lethal 3 (RSL3), also known a ferroptosis inducer, is synthetic GPX4 inhibitor. Therefore, we hypothesized that RSL3 can amplify CAP-induced inhibition GPX4. In this study, showed loaded poly (ethylene glycol)-block-poly(lactide-co-glycolide) (PLGA-PEG) nanoparticles enhance deaths 4T1 tumor Furthermore, combination CAP promoted immunogenic (ICD), induced dendritic (DC) maturation, macrophage polarization, initiating tumor-specific T-cell mediated immune responses against tumors. For vivo application, RSL3@NP was co-delivered with via injectable Pluronic hydrogel. 4T1-bearing mice, hydrogel-mediated delivery RSL3-loaded effectively elicit potent anti-tumor inhibit growth.

Aberrant lipid metabolism is a well-recognized hallmark of cancer. Notably, breast cancer (BC) arises from lipid-rich microenvironment and depends significantly on metabolic reprogramming to fulfill its developmental requirements. In this review, we revisit the pivotal role in BC, underscoring impact progression tumor microenvironment. Firstly, delineate overall landscape highlighting roles patient prognosis. Given that lipids can also act as signaling molecules, next describe exchanges between BC cells other cellular components Additionally, summarize therapeutic potential targeting aspects processes, lipid-related transcription factors immunotherapy BC. Finally, discuss possibilities problems associated with clinical applications lipid‑targeted therapy propose new research directions advances spatiotemporal multi-omics.

Colorectal cancer (CRC) is the second most common in men and third females, a heterogeneous disease involving multistep mechanisms that represents 10% of all cancers globally. This study investigates gene mutation profiling CRC using Next-Generation sequencing machine. Formalin-fixed paraffin-embedded tissues 30 patients were retrieved reviewed. DNA was isolated from selected tissues. Desirable quality check Qubit Nanoquant machine done, desirable libraries prepared loaded into sequencer for sequencing. Using Illumina BaseSpace Variant interpreter, generated FastQ data treated annotation, alignment, mapping with reference genome. Sequencing-runs Phred-score ≥ as runs. Finally, variants validated on NCBI-dsSNP Ensembl databases clinical consequence interpretations. Overall, patient distribution consists 12(40%) females 18 (60%) males mean age (53.2 + 5.3). TNM stage-3: 53.3% (15/30) least Stage-4: 20%(6/30) respectively. 73.3%: (22/30) completed sequencing, 552 mutations 29 genes 12 chromosomes detected. The upregulated are KIT:68(12.3%), FGFR4:61(11.1%), EGFR:60(10.9%), ALK:53(9.6%), DCUN1D1:41(7.4%), PDGFR:40(7.2%), KRAS:33(6.0%), CDK4:27(4.9%), FGFR3:26(4.7%), MTOR:14(2.6), while NRAS, CDK6, PIK3CA, RET each has 13(2.4%) apiece. Chromosomes 4:134/55(24.2%), chr7:84/552(15.2%), chr12:71/552(12.9%), chr5:64/552(11.6%), chr2:61/552(11.1%), chr3:54/552(9.8%), chr1:43/552(7.8%) involved chromosomes. Nine (APC, ALK, KRAS, IDH1, FGFR1, ERBB2, ESR1) identified pathogenic-causing CRC. first NGS-based molecular FFPE-CRC hospital-USM showed nine crucial pathogenic variants.

Abstract Non‐small cell lung cancer (NSCLC) presents significant therapeutic challenges, often characterized by aggressive proliferation and metastasis. This study investigates the role of SLC7A11, a ferroptosis‐related gene, in NSCLC progression potential engineered bacterial extracellular vesicles (BEVs) expressing SLC7A11‐targeting siRNA as strategy. Using TCGA GEO databases, we identified that SLC7A11 was significantly upregulated tissues. Functional assays demonstrated knockdown lines (NCI‐H2122 NCI‐H647) via qPCR, Western blot, immunofluorescence resulted impaired proliferation, migration, invasion abilities. In vivo xenograft models further revealed inhibited tumor growth metastasis, corroborated histological analyses. To enhance targeted delivery siRNA, BEVs with targeting peptide, verifying their structure function through transmission electron microscopy (TEM) nanoparticle tracking analysis (NTA). toxicity assessments indicated safety for these bioengineered vesicles. Importantly, treatment BEVs‐LCTP‐siSLC7A11 not only tumorigenesis but also activated ferroptosis pathways, evidenced altered expression levels transferrin metastatic Our findings suggest promising approach to inhibit while activating ferroptosis, offering insights into novel strategies against cancer.
