Abstract
Cerebral ischemic stroke is one of the foremost global causes of death and disability. Due to inadequate knowledge in its sequential disease mechanisms, therapeutic efforts to mitigate acute ischemia-induced brain injury are limited. Recent studies have implicated epigenetic mechanisms, mostly histone lysine acetylation/deacetylation, in ischemia-induced neural damage and death. However, the role of lysine methylation/demethylation, another prevalent epigenetic mechanism in cerebral ischemia has not undergone comprehensive investigation, except a few recent reports, including those from our research cohort. Considering the impact of sex on post-stroke outcomes, we studied both male and female mice to elucidate molecular details using our recently developed Internal Carotid Artery Occlusion (ICAO) model, which induces mild to moderate cerebral ischemia, primarily affecting the striatum and ventral hippocampus. Here, we demonstrate for the first time that female mice exhibit faster recovery than male mice following ICAO, evaluated through neurological deficit score and motor coordination assessment. Furthermore, our investigation unveiled that dysregulated histone lysine demethylases (KDMs), particularly kdm4b/jmjd2b are responsible for the sex-specific variance in the modulation of inflammatory genes. Building upon our prior reportage blocking KDMs by DMOG (Dimethyloxalylglycine) and thus preventing the attenuation in H3k9me2 reduced the post-ICAO transcript levels of the inflammatory molecules and neural damage, our present study delved into investigating the differential role of H3k9me2 in the regulation of pro-inflammatory genes in female vis-à-vis male mice underlying ICAO-induced neural damage and recovery. Overall, our results reveal the important role of epigenetic mark H3k9me2 in mediating sex-specific sequential events in inflammatory response, elicited post-ICAO.

Abstract
Myocardial hypoxia reperfusion (H/R) injury is the paradoxical exacerbation of myocardial damage, caused by the sudden restoration of blood flow to hypoxia affected myocardium. It is a critical contributor of acute myocardial infarction, which can lead to cardiac failure. Despite the current pharmacological advancements, clinical translation of cardioprotective therapies have proven challenging. As a result, researchers are looking for alternative approaches to counter the disease. In this regard, nanotechnology, with its versatile applications in biology and medicine, can confer broad prospects for treatment of myocardial H/R injury. Herein, we attempted to explore whether a well-established pro-angiogenic nanoparticle, terbium hydroxide nanorods (THNR) can ameliorate myocardial H/R injury. For this study, in vitro H/R-injury model was established in rat cardiomyocytes (H9c2 cells). Our investigations demonstrated that THNR enhance cardiomyocyte survival against H/R-induced cell death. This pro-survival effect of THNR is associated with reduction of oxidative stress, lipid peroxidation, calcium overload, restoration of cytoskeletal integrity and mitochondrial membrane potential as well as augmentation of cellular anti-oxidant enzymes such as glutathione-s-transferase (GST) and superoxide dismutase (SOD) to counter H/R injury. Molecular analysis revealed that the above observations are traceable to the predominant activation of PI3K-AKT-mTOR and ERK-MEK signalling pathways by THNR. Concurrently, THNR also exhibit apoptosis inhibitory effects mainly by suppression of pro-apoptotic proteins like Cytochrome C, Caspase 3, Bax and p53 with simultaneous restoration of anti-apoptotic protein, Bcl-2 and Survivin. Thus, considering the above attributes, we firmly believe that THNR have the potential to be developed as an alternative approach for amelioration of H/R injury in cardiomyocytes.

Abstract
Critical limb ischemia (CLI) is considered as a severe type of peripheral artery diseases (PADs) which occurs due to the inadequate supply of blood to the limb extremities. CLI patients often suffer from extreme cramping pain, impaired wound healing, immobility, cardiovascular complications, amputation of the affected limb and even death. The conventional therapy for the treatment of CLI includes surgical revascularization as well as restoring angiogenesis using growth factor therapy. However, surgical revascularization is suitable for only a minor percentage of CLI patients and it is associated with high perioperative mortality rate. The use of growth factors is also limited in terms of their poor therapeutic angiogenesis potential as observed by the earlier clinical studies, which could be attributed to their poor bio-availability and non-specificity issues. Therefore, to outweigh the aforesaid disadvantages of the conventional strategies, there is an utmost need for the advancement of new alternative therapeutic biomaterials to treat CLI. Since past few decades, various research groups including ours have been involved in developing different pro-angiogenic nanomaterials. Among them, zinc oxide nanoflowers (ZONF), established in our laboratory, are considered as one of the potent nanoparticles to induce therapeutic angiogenesis. In our earlier studies, we have depicted that ZONF promote angiogenesis by inducing the formation of reactive oxygen species (ROS) and nitric oxide (NO) as well as activating Akt/MAPK/eNOS cell signaling pathways in the endothelial cells. Recently, we have also reported the therapeutic potential of ZONF to treat cerebral ischemia through their neuritogenic and neuroprotective properties, exploiting angio-neural cross talk. Considering the excellent pro-angiogenic properties of ZONF and importance of revascularization for the recovery of CLI, in this present study, we have comprehensively explored the therapeutic potential of ZONF in a rat hind limb ischemia model (established by ligating the femoral artery of hind limb), an animal model that mimics CLI in humans. The behavioural studies, laser Doppler perfusion imaging, histopathology, immunofluorescence as well as estimation of serum NO level depicted that the administration of ZONF could ameliorate the ischemic conditions in rats at a faster rate by promoting therapeutic angiogenesis to the ischemic sites. Altogether, the present study offers an alternative nanomedicine approach employing ZONF for the treatment of PADs.

Abstract
Functionalized cerium oxide nanoparticle (CeNP)-loaded fibro-porous poly-l-lactic acid (PLLA)/gelatin composite membranes were prepared via an electrospinning technology. Considering the importance of such membrane scaffolds for promoting angiogenesis in tissue engineering and drug screening, a series of PLLA/gelatin composite fiber membranes loaded with different doses of CeNPs was prepared. The prepared composite membranes demonstrated hydrophilicity, water absorption, and improved mechanical properties compared to a PLLA and PLLA/gelatin membrane. Also, cell viability assay using somatic hybrid endothelial cells (EA.hy926) proved the biocompatible nature of the scaffolds. The biocompatibility was further supported by in vivo chick embryo angiogenesis assay using fertilized eggs. Our initial results support that these membrane scaffolds could be useful for angiogenesis-related disease treatment after further investigations.
