A change in protein expression, the functional moiety for molecular events, may result in altered healing of RCT and prolonged morbidity. Expression and activity of proteins are critical while investigating the underlying molecular and cellular changes involved in tendinopathy. While investigating the changes in the protein expression of various inflammatory mediators, we observed that the Western Blot bands for commonly used housekeeping genes (GAPDH, β-actin, and α-tubulin) were not uniform in different tendon samples. Therefore, we investigated for an optimal housekeeping gene for Western blot analysis in swine RCT under normal and hyperlipidemic conditions, as this is essential for accurate normalization of protein expression. The study evaluated several housekeeping genes-GAPDH, beta-actin, alpha and beta-tubulin, Ubiquitin C, Cyclophilin A, TATA-box binding protein, and 14-3-3ζ-to ensure robust normalization across experimental setups. The results revealed that the protein expression of 14-3-3ζ was uniform in all samples, thereby validating its suitability as a stable housekeeping protein. The findings are important while studying the RCT pathology in a clinically relevant animal model, like swine, which mimics human RCT and provides translationally significant findings.

Angiogenesis is a critical hallmark of glioma progression. However, the regulatory role and underlying mechanism of lncRNA brain-derived neurotrophic factor-antisense (BDNF-AS) in glioma angiogenesis remain poorly understood and warrant further investigation. Malignant characteristics of glioma cells were evaluated using CCK-8, colony formation, scratch, transwell, flow cytometry, and tube formation assays. The expression levels of genes and proteins were detected by RT-qPCR, western blot, and IHC assays. The methylation level of NEDD4-like E3 ubiquitin protein ligase (NEDD4L) was determined using MSP. The interactions among molecules were validated using RIP, ChIP, and Co-IP. Our study revealed significantly downregulated BDNF-AS expression in glioma cells. BDNF-AS overexpression markedly attenuated the malignant characteristics of glioma cells, as evidenced by decreased viability, proliferation, migration, invasion, and angiogenesis, along with increased apoptosis. These tumor-suppressive effects were significantly abrogated by NEDD4L knockdown. Mechanistically, BDNF-AS could interact with DNA methyltransferase 1 (DNMT1) expression, leading to reduced NEDD4L promoter methylation and upregulation of NEDD4L expression. Additionally, NEDD4L-mediated promotion of YAP1 ubiquitination to decline YAP1 and VEGFA expression. Finally, BDNF-AS exerted potent anti-tumor effects by mediating NEDD4L/YAP1/VEGFA axis, as demonstrated by suppressed tumor growth in glioma-bearing mice and attenuated malignant features in glioma cells.

Anti-melanoma differentiation-associated gene 5-positive dermatomyositis-associated interstitial lung disease (MDA5-ILD), a subtype, is associated with high mortality due to rapid progression and severe lung damage. Volatile organic compounds (VOCs) in exhaled breath, reflecting metabolic changes, have been identified as potential non-invasive biomarkers for various diseases, including respiratory conditions. However, their role in MDA5-ILD has not been extensively studied. This retrospective cohort study included 45 exhaled breath samples from 19 ILD patients, with 31 samples from 9 patients with MDA5-ILD and 10 samples from 7 patients with non-MDA5-ILD. VOCs were collected using thermal desorption tubes and analyzed via gas chromatography-mass spectrometry (GC-MS). Clinical data, including the APACHE II score, were integrated with VOC profiles. Two logistic regression models were developed: Model 1 based on 11 clinical indicators, and Model 2 integrating 11 clinical indicators with 5 VOC features. Model performance was evaluated using receiver operating characteristic (ROC) curve analysis, sensitivity, specificity, and accuracy metrics. Five VOCs-N-(2-Aziridinyl)ethanamine, Cyclohexanone, Nonanal, Dodecamethylcyclohexasiloxane, and 4-Methyltetradecane-were identified as significant biomarkers distinguishing MDA5-ILD from non-MDA5-ILD. Model 2, which integrated VOC data, outperformed Model 1, achieving an area under the curve (AUC) of 0.93 compared to 0.70. Model 2 also demonstrated enhanced accuracy (84.6% vs. 76.9%), specificity (66.7% vs. 33.3%), precision (90.0% vs. 81.8%), and F1-score (90.0% vs. 85.7%). Additionally, 1,3-Pentadiene and 3-Methylundecane were identified as potential markers of disease severity, with 1,3-Pentadiene negatively correlating and 3-Methylundecane positively correlating with both APACHE II scores and creatinine levels. VOCs in exhaled breath significantly enhance the diagnostic sensitivity and accuracy for detecting MDA5-ILD. In addition, VOCs show promise as disease severity markers, potentially aiding in the assessment of disease severity and progression.

However, quick degradation and poor cellular uptake limit their regenerative capacity. Thanks to their adjustable characteristics, hydrogels can act as vehicles for transporting and sustainably releasing miRNA-SC-EVs at injury sites. Therefore, a systematic literature review was conducted on miRNA-enriched SC-EVs incorporated into hydrogels in animal skin regeneration models published from 2010 to 2024 (PROSPERO ID: CRD42024588072). Out of the 89 records, 12 met the criteria. Diabetic wounds are characterized by chronic inflammation, oxidative stress, and defective macrophage polarization, resulting in less satisfactory regeneration. The hydrogels tackled these issues by shifting macrophages from a pro-inflammatory M1 phenotype to a healing M2 phenotype, promoting collagen production, enhancing fibroblast movement, and boosting angiogenesis. Burn injuries frequently lead to slow recovery due to hypertrophic scarring, extended inflammation, and infection. Hyaluronic acid (HA)-derived hydrogels, infused with miR-21-5p and surface-treated with polydopamine and cationic antimicrobial peptides, promoted wound healing by lowering scarring and demonstrating anti-inflammatory, anti-apoptotic, and pro-angiogenic characteristics. The cell adhesion of these hydrogels can be enhanced by adding MOFs, chitosan, and extracellular matrix elements.

Studies indicate that individuals with T2DM have a 10-20% increased risk of developing various solid tumors, including colorectal, breast, pancreatic, and liver cancers. The relative risk (RR) varies depending on cancer type, with pancreatic and liver cancers showing a particularly strong association (RR 2.0-2.5), while colorectal and breast cancers demonstrate a moderate increase (RR 1.2-1.5). Understanding these epidemiological trends is crucial for developing integrated management strategies. Given the global rise in T2DM and cancer cases, exploring the complex relationship between these conditions is critical. IR contributes to hyperglycemia, chronic inflammation, and altered lipid metabolism. Together, these factors create a pro-tumorigenic environment conducive to cancer development and progression. In individuals with IR, hyperinsulinemia triggers the insulin-insulin-like growth factor (IGF1R) signaling pathway, activating cancer-associated pathways such as mitogen-activated protein kinase (MAPK) and phosphatidylinositol 3-kinase (PIK3CA), which promote cell proliferation and survival, thereby supporting tumor growth. Both IR and T2DM are linked to increased morbidity and mortality in patients with cancer. By providing an in-depth analysis of the molecular links between insulin resistance and cancer, this review offers valuable insights into the role of metabolic dysfunction in tumor progression.
