The NatA complex is composed of the NAA10, NAA15, and HYPK subunits. It primarily responsible for N-terminal acetylation, a critical post-translational modification in eukaryotes. Pathogenic variants within NAA10 cause Ogden Syndrome (OS), which characterized by varying degrees intellectual disability, hypotonia, developmental delay, cardiac abnormalities. Although manifestations disease have been described extensively case reports, there has not study focusing on their recommended clinical management. In this study, we describe OS cohort 85 probands. We found increased incidence structural electrophysiologic abnormalities, with particularly high prevalence QT interval prolongation. Sub-analysis showed that male probands those NAA15-binding domain had more severe phenotypes than females or outside domain.

Abstract Lung carcinoma incidence and fatality rates remain among the highest on a global scale. The efficacy of targeted therapies immunotherapies is commonly compromised by emergence drug resistance other factors, resulting in lack durable therapeutic benefits. Ferroptosis, distinct pattern cell death marked buildup iron-dependent lipid peroxides, has been shown to be novel potentially more effective treatment for lung carcinoma. However, mechanism regulatory network ferroptosis are exceptionally complex, many unanswered questions remain. In addition, research diagnosis cancer growing exponentially. Therefore, it necessary provide thorough summary latest advancements field ferroptosis. Here, we comprehensively analyze mechanisms underlying preconditions ferroptosis, defense system, associated molecular networks. potential strategies also highlighted. Targeting improves tumor enhances effectiveness drugs immunotherapies. These findings may shed fresh light management carcinoma, as well development related

Ferroptosis is a distinct form of iron-dependent programmed cell death characterized primarily by intracellular iron accumulation and lipid peroxidation. Multiple cellular processes, including amino acid metabolism, various signaling pathways, autophagy, have been demonstrated to influence the induction progression ferroptosis. Recent investigations elucidated that ferroptosis plays crucial role in pathogenesis pulmonary disorders, lung injury, chronic obstructive disease, fibrosis, asthma. increasingly recognized as promising novel strategy for cancer treatment. Various immune cells within tumor microenvironment, CD8+ T cells, macrophages, regulatory natural killer dendritic shown induce modulate process through regulation metabolism pathways. Conversely, can reciprocally alter metabolic environment, leading activation or inhibition functions, thereby modulating responses. This paper reviews molecular mechanism describes discusses connection between microenvironment diseases, development prospect their interaction treatment diseases.

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.

Tyrosine kinase inhibitors (TKIs) are the first-line therapy for patients with non-small cell lung cancer (NSCLC) sensitized mutations in epidermal growth factor receptor (EGFR). However, resistance to TKIs is a major clinical issue that affects survival and prognosis of patients, mechanisms underlying this remaining elusive. Circular RNAs (circRNAs) class single-stranded, covalently closed RNA molecules, which generated from pre-messenger (mRNAs) through back splicing. The aim study was investigate role cRNA SPECC1 promoting NSCLC explore its potential involvement tumorigenesis metastasis adenocarcinoma (LUAD). In study, we identified differentially expressed genes sequencing three tumor samples obtained poor postoperative TKI treatment outcomes. Validation performed using quantitative real-time polymerase chain reaction (qRT-PCR) function experiments. We further constructed competing endogenous (ceRNA) network Gene Ontology (GO) analysis circRNA. circular (circSPECC1) found be significantly upregulated tumors as compared adjacent tissues. Knockdown circSPECC1 lines resulted decreased proliferation, migration, invasion. Additionally, apoptosis increased TKI-sensitive EGFR when treated osimertinib. may promote contribute NSCLC.
