Abstract
The tumor stroma, or the microenvironment surrounding solid tumors, can significantly impact the effectiveness of cancer therapies. The tumor microenvironment is characterized by high interstitial pressure, a consequence of leaky vasculature, and dense stroma created by excessive deposition of various macromolecules such as collagen, fibronectin, and hyaluronic acid (HA). In addition, non-cancerous cells such as cancer-associated fibroblasts (CAFs) and the extracellular matrix (ECM) itself can promote tumor growth. In recent years, there has been increased interest in combining standard cancer treatments with stromal-targeting strategies or stromal modulators to improve therapeutic outcomes. Furthermore, the use of nanomedicine, which can improve the delivery and retention of drugs in the tumor, has been proposed to target the stroma. This review focuses on how different stromal components contribute to tumor progression and impede chemotherapeutic delivery. Additionally, this review highlights recent advancements in nanomedicine-based stromal modulation and discusses potential future directions for developing more effective stroma-targeted cancer therapies.

Abstract
Our earlier reports established that zinc oxide nanoflowers (ZONF) show significant pro-angiogenic properties, where reactive oxygen species, nitric oxide and MAPK-AKT-eNOS cell signaling axis play an essential task. Considering the significance of angiogenesis in healthcare, our research group has recently demonstrated the in vivo therapeutic application of ZONF (10 mg/kg b.w.) for treating peripheral artery disease. Moreover, based on the angio-neural crosstalk between vascular and neuronal systems, we have further demonstrated the neuritogenic and neuroprotective characteristics of pro-angiogenic nanoflowers (10 mg/kg b.w.) for the treatment of cerebral ischemia. However, it is crucial for a therapeutic material to be non-toxic for its practical clinical applications and therefore assessment of its in vivo toxicity and adverse effect is highly important. Herein, for the first time, we investigate a detailed nanotoxicology of therapeutically active ZONF in Swiss albino mice to evaluate their safety profile and comprehend their aspects for future clinical applications. The maximum tolerated dose (MTD) of ZONF was found to be 512.5 mg/kg b.w. which was employed for acute exposure (2 weeks), showing slight toxicity. However, sub-chronic (4 weeks) and long term chronic (8-12 weeks) studies of nanoflowers exhibited their non-toxic nature particularly at lower therapeutic doses (1-10 mg/kg b.w.). Additionally, in depth genotoxicity study revealed that lower therapeutic dose of ZONF (10 mg/kg b.w.) did not exhibit significant toxicity even in genetic level. Overall, the present nanotoxicology of ZONF suggests their high biocompatible nature at therapeutic dose, offering the basis of their future clinical applications in ischemic and other vascular diseases.

Abstract
Mesenchymal stem cells (MSCs) have been studied for their potential in facilitating tumor-targeted delivery of chemotherapeutics due to their tumor-homing characteristics. We hypothesized that targeting effectiveness of MSCs can be further enhanced by incorporating tumor-targeting ligands on MSC surfaces that will allow for enhanced arrest and binding within the tumor tissue. We utilized a unique strategy of modifying MSCs with synthetic antigen receptors (SARs), targeting specific antigens overexpressed on cancer cells. MSCs were surface-functionalized by first incorporating recombinant protein G (PG) on the surface, followed by binding of the targeting antibody to the PG handle. We functionalized MSCs with antibodies targeting a tyrosine kinase transmembrane receptor protein, epidermal growth factor receptor (EGFR), overexpressed in non-small-cell lung cancer (NSCLC). The efficacy of MSCs functionalized with anti-EGFR antibodies (cetuximab and D8) was determined in murine models of NSCLC. Cetuximab-functionalized MSCs demonstrated improved binding to EGFR protein and to EGFR overexpressing A549 lung adenocarcinoma cells. Further, cetuximab-functionalized MSCs loaded with paclitaxel nanoparticles were efficient in slowing orthotopic A549 tumor growth and improving the overall survival relative to that of other controls. Biodistribution studies revealed a six-fold higher retention of EGFR-targeted MSCs than non-targeted MSCs. Based on these results, we conclude that targeting ligand functionalization could be used to enhance the concentration of therapeutic MSC constructs at the tumor tissue and to achieve improved antitumor response.

Abstract
Mesenchymal stem cells (MSCs) are multipotent cells and are considered a potential source for tissue and organ repair due to their self-renewal, proliferation, and differentiation abilities. However, in most cases, MSCs are needed to be stimulated with external growth factors to promote their proliferation and differentiation. Over the past decade, it has been demonstrated that nanomaterials could facilitate MSC proliferation and differentiation, and excellent efforts are carried out to investigate their possible modulating pattern and mechanisms for MSC differentiation. Europium hydroxide (EuIII(OH)3) nanorods (EHN) are well-researched for their biomimicking properties and act as a substitute for growth factors that induce cell proliferation, migration, and differentiation. In the current study, the human mesenchymal stem cells (MSCs) were chosen as an in vitro model for evaluating the role of EHN in modulating the differentiation process of MSCs into neuronal and glial lineages. The characterization of MSCs and differentiated neuronal cells observed by flow cytometry, confocal, and gene marker expression studies supported our hypothesis that the EHNs are pro-angiogenic and pro-neurogenic. Finally, altogether our results suggest that EHNs have the potential to play an essential part in developing novel treatment strategies for neurodegenerative diseases (ND) and spinal cord injuries (SCI) based on the nanomedicine approach.

Abstract
Abstract
Mesenchymal stem cells (MSCs) are being investigated for several therapeutic applications, including cancer, inflammation, tissue repair, and transplantation because of their ability to home to injured and inflamed tissues. Despite the large number of preclinical studies investigating engineered MSCs as therapeutic agents and numerous clinical trials investigating MSCs for other therapeutic applications, there have only been a handful of clinical trials investigating MSCs for treating solid tumors, and none have progressed beyond Phase I/II. Inefficient tumor homing ability and a lack of understanding of fundamental mechanisms may contribute to the limited translational success of MSC-based therapies. We hypothesized that nanoengineering MSCs with anticancer drugs induces oxidative stress, and MSCs counteract this stress by activating Nrf2, which increases the expression of various antioxidant proteins, including CXCR4, a key mediator of MSC tumor homing. We performed global label-free, unbiased proteomics on nanoengineered MSCs using modified in-Stage technology. Our studies indicated that MSCs nanoengineered with paclitaxel underwent significant changes in the overall proteome compared to either untreated MSCs or MSCs loaded with blank nanoparticles. Analysis of molecular function profile revealed that loading paclitaxel in MSCs significantly enhanced the expression of proteins involved in the antioxidant and catalytic activity and protein binding. The biological process profile also showed a similar increase in defense response and an increase in metabolic processes. It was further found that MSCs nanoengineered with PTX lead to significant upregulation of nrf2, the master regulator of antioxidant responses, and CXCR4, a direct target of Nrf2 and a key mediator of tumor homing. Also, an increase in CXCR4 expression was directly proportional to paclitaxel loading in cells. These studies suggest nanoengineering of MSCs impacts their biology, which likely contributes to their improved tumor homing capacity in vivo.

Abstract
Nanotechnology has immensely advanced the field of cancer diagnostics and treatment by introducing potential delivery vehicles as carriers for drugs or therapeutic agents. In due course, mesoporous silica nanoparticles (MSNs) have emerged as excellent vehicles for delivering drugs, biomolecules, and biomaterials, attributed to their solid framework and porosity providing a higher surface area for decorating with various functional ligands. Recently, the metal tin (Sn) has gained huge importance in cancer research owing to its excellent cytotoxicity and ability to kill cancer cells. In the present work, we synthesized MSNs, conjugated them with organotin compounds, and characterized them using various physicochemical techniques. Subsequently, the biological evaluation of MSN (S1), MSN-MP (S2) and tin-conjugated MSNs (S3: MSN-MP-SnPh3) (MP = 3-mercaptopropyltriethoxysilane) revealed that these nanoconjugates induced cytotoxicity, necrosis, and apoptosis in MCF-7 cells. Moreover, these nanoconjugates exhibited anti-angiogenic properties as demonstrated in the chick embryo model. The increase of reactive oxygen species (ROS) was found as a one of the plausible mechanisms underlying cancer cell cytotoxicity induced by these nanoconjugates, encouraging their application for the treatment of cancer. The tin-conjugated MSNs demonstrated less toxicity to normal cells compared to cancer cells. Furthermore, the genotoxicity studies revealed the clastogenic and aneugenic effects of these nanoconjugates in CHO cells mostly at high concentrations. These interesting observations are behind the idea of developing tin-conjugated MSNs as prospective candidates for anticancer therapy.

Abstract
Heterogeneity in tumor expression as well as expression in normal tissues of various targets limit the usefulness of current ligand-based active targeting approaches. Incorporation of synthetic receptors, which can be recognized by delivery systems engineered to present specific functional groups on the surface, is a novel approach to improve tumor targeting. Alternatively, introduction of synthetic functionalities on cellular carriers can also enhance tumor targeting. We review various strategies that have been utilized for the introduction of synthetic targets in tumor tissues. The introduction of synthetic functional groups in the tumor through improved strategies is anticipated to result in improved target specificity and reduced heterogeneity in target expression.

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
Abstract
Targeted delivery can improve drug accumulation in tumor tissue and treatment outcomes. However, currently available options suffer from a lack of selectivity for tumor cells. Mesenchymal Stem cells (MSCs) can be engineered with chemotherapeutic-loaded polymeric nanoparticles (PNPs) for tumor-targeted delivery, owing to their characteristic tumor tropic properties. Although nano-engineered MSCs demonstrated significant anticancer activity in multiple ovarian cancer models, their non-specific accumulation in clearance organs such as lungs and liver remains a concern. Parallel to the concept of chimeric antigen receptor (CAR)-T cell therapy, we advance here a strategy of modifying MSCs with synthetic antigen receptors (SARs) that target specific antigens overexpressed on cancer cells. Our approach consists of stably incorporating recombinant protein G (PG) on the surface of MSCs, followed by binding of a full-length IgG to the PG handle. Because protein G binds to the Fc region of IgG, antigen-binding affinity of the antibody is conserved. Epidermal growth factor receptor (EGFR) has been reported to be overexpressed and implicated in the pathogenesis of several malignancies especially lung cancer. Cetuximab (Cmab) is an anti-EGFR monoclonal antibody used in the treatment of metastatic lung cancer. In the current study, SAR-MSCs were developed by coating the nano-engineered MSCs with palmitated PG, followed by incorporating Cmab on the cell surface. Flow cytometry and confocal microscopy were used to confirm the incorporation of fluorescently labeled PAPG handle on MSC surface. Similarly, the installation of fluorescently labeled antibody on PAPG-functionalized MSCs was confirmed by flow cytometry. Preliminary efficacy studies in a mouse orthotopic A549-luc human lung adenocarcinoma model demonstrated significantly (P<0.05) improved survival of mice treated with Cmab-modified nano-engineered MSCs compared to isotype IgG-modified nano-engineered MSCs control group. These results suggest that the SAR technology could further improve the effectiveness of MSCs as tumor targeted drug delivery vehicles.

Abstract
In spite of radical advances in nanobiotechnology, the clinical translation of nanoparticle (NP)-based agents is still a major challenge due to various physiological factors that influence their interactions with biological systems. Recent decade witnessed meticulous investigation on protein corona (PC) that is the first surrounds NPs once administered into the body. Formation of PC around NP surface exhibits resilient effects on their circulation, distribution, therapeutic activity, toxicity and other factors. Although enormous literature is available on the role of PC in altering pharmacokinetics and pharmacodynamics of NPs, understanding on its analytical characterization methods still remains shallow. Therefore, the current review summarizes the impact of PC on biological fate of NPs and stressing on analytical methods employed for studying the NP-PC.

Abstract
Neuritogenesis, a complex process of the sprouting of neurites, plays a vital role in the structural and functional restoration of cerebral ischemia-injured neuronal tissue. Practically, there is no effective long-term treatment strategy for cerebral ischemia in clinical practice to date due to several limitations of conventional therapies, facilitating the urgency to develop new alternative therapeutic approaches. Herein, for the first time we report that pro-angiogenic nanomaterials, zinc oxide nanoflowers (ZONF), exhibit neuritogenic activity by elevating mRNA expression of different neurotrophins, following PI3K/Akt-MAPK/ERK signaling pathways. Further, ZONF administration to global cerebral ischemia-induced Fischer rats shows improved neurobehavior and enhanced synaptic plasticity of neurons via upregulation of Neurabin-2 and NT-3, revealing their neuroprotective activity. Altogether, this study offers the basis for exploitation of angio-neural cross talk of other pro-angiogenic nano/biomaterials for future advancement of alternative treatment strategies for cerebral ischemia, where neuritogenesis and neural repair are highly critical.

Abstract
Mesenchymal stem cells (MSCs) have previously demonstrated considerable promise in regenerative medicine based on their ability to proliferate and differentiate into cells of different lineages. More recently, there has been a significant interest in using MSCs as cellular vehicles for targeted cancer therapy by exploiting their tumor homing properties. Initial studies focused on using genetically modified MSCs for targeted delivery of various proapoptotic, antiangiogenic, and therapeutic proteins to a wide variety of tumors. However, their use as drug delivery vehicles has been limited by poor drug load capacity. This review discusses various strategies for the nongenetic modification of MSCs that allows their use in tumor-targeted delivery of small molecule chemotherapeutic agents. SIGNIFICANCE STATEMENT: There has been considerable interest in exploiting the tumor homing potential of MSCs to develop them as a vehicle for the targeted delivery of cytotoxic agents to tumor tissue. The inherent tumor-tropic and drug-resistant properties make MSCs ideal carriers for toxic payload. While significant progress has been made in the area of the genetic modification of MSCs, studies focused on identification of molecular mechanisms that contribute to the tumor tropism along with optimization of the engineering conditions can further improve their effectiveness as drug delivery vehicles.

In the current study, we investigated the incorporation of anti-perlecan antibody on the surface of nano-engineered MSCs. The anti-perlecan IgG antibody was first derivatized with palmitic acid (PA), which was then used to insert PG on MSCs cell membrane. We characterized the PAPG derivative by LC/Q-TOF/MS. Flow cytometry and confocal microscopy were used to confirm the incorporation of fluorescently labeled PAPG handle on MSC surface. Similarly, the binding of fluorescently labeled anti-perlecan IgG to PAPG-functionalized MSCs was confirmed by flow cytometry. We are currently investigating the anticancer efficacy of paclitaxel-loaded, anti-perlecan SAR-MSCs using in vitro and mouse models of ovarian cancer.

Abstract
SIGNIFICANCE Redox signaling plays a vital role in regulating various cellular signaling pathways and disease biology. Recently, nanomedicine (application of nanotechnology in biology and medicine) has been demonstrated to regulate angiogenesis through redox signaling. A complete understanding of redox signaling pathways influenced angiogenesis/antiangiogenesis triggered by therapeutic nanoparticles is extensively reviewed in this article. Recent Advances: In recent times, nanomedicines are regarded as the Trojan horses that could be employed for successful drug delivery, gene delivery, peptide delivery, disease diagnosis, and others, conquering barriers associated with conventional theranostic approaches. CRITICAL ISSUES Physiological angiogenesis is a tightly regulated process maintaining a balance between proangiogenic and antiangiogenic factors. The redox signaling is one of the main factors that contribute to this physiological balance. An aberrant redox signaling cascade can be caused by several exogenous and endogenous factors and leads to reduced or augmented angiogenesis that ultimately results in several disease conditions. FUTURE DIRECTIONS Redox signaling-based nanomedicine approach has emerged as a new platform for angiogenesis-related disease therapy, where nanoparticles promote angiogenesis via controlled reactive oxygen species (ROS) production and antiangiogenesis by triggering excessive ROS formation. Recently, investigators have identified different efficient nano-candidates, which modulate angiogenesis by controlling intracellular redox molecules. Considering the importance of angiogenesis in health care a thorough understanding of nanomedicine-regulated redox signaling would inspire researchers to design and develop more novel nanomaterials that could be used as an alternative strategy for the treatment of various diseases, where angiogenesis plays a vital role.

Abstract
During the last decade, metal nanoparticles (MtNPs) have gained immense popularity due to their characteristic physicochemical properties, as well as containing antimicrobial, anti-cancer, catalyzing, optical, electronic and magnetic properties. Primarily, these MtNPs have been synthesized through different physical and chemical methods. However, these conventional methods have various drawbacks, such as high energy consumption, high cost and the involvement of toxic chemical substances. Microbial flora has provided an alternative platform for the biological synthesis of MtNPs in an eco-friendly and cost effective way. In this article we have focused on various microorganisms used for the synthesis of different MtNPs. We also have elaborated on the intracellular and extracellular mechanisms of MtNP synthesis in microorganisms, and have highlighted their advantages along with their challenges. Moreover, due to several advantages over chemically synthesized nanoparticles, the microbial MtNPs, with their exclusive and dynamic characteristics, can be used in different sectors like the agriculture, medicine, cosmetics and biotechnology industries in the near future.

Abstract
Since the last decade, the metal composite nanostructures have evolved as promising candidates in regard to their wide applications in the fields of science and engineering. Recently, several investigators identified the titanium based nanomaterials as excellent agents for multifunctional environmental and biomedical applications. In this perspective, we have developed a series of zinc-doped (2 and 5%) titanium oxide-based nanomaterials using various reaction conditions and calcination temperatures (TZ1-TZ3: calcined at 500°C, TZ4-TZ6: calcined at 600°C and TZ7-TZ9: calcined at 700°C). The calcined materials (TZ1 to TZ9) were thoroughly analyzed by several physico-chemical characterization methods. The increase of the calcination temperature results in significant changes of the textural properties of the nanostructured materials. In addition, the increase of the calcination temperature leads to the formation of anatase/rutile mixtures with higher quantity of rutile. Furthermore, incorporation of zinc changes the morphology of the obtained nanoparticles. The materials were studied in the photodegradation of methylene blue observing that materials calcined at lower temperatures (TZ1-TZ3) have higher photocatalytic activity than those of the materials calcined at 600°C (TZ4-TZ6), rutile-based systems TZ7-TZ9 are not active. Based on the background literature of titanium and zinc based nanostructures in therapeutic angiogenesis, we have explored the pro-angiogenic properties of these materials using various in vitro and in vivo assays. The zinc-doped titanium dioxide nanostructures (TZ5 and TZ6) exhibited increased cell viability, proliferation, enhanced S-phase cell population, increased pro-angiogenic messengers (ROS: reactive oxygen species and NO: nitric oxide) production and promoted in vivo blood vessel formation in a plausible mechanistic p38/STAT3 dependent signaling cascade. Altogether, the results of the present study showcase these zinc doped-titanium oxide nanoparticles as promising candidates for environmental (water-remediation) and therapeutic angiogenic applications.

Abstract
Angiogenesis, a process resulting in the formation of new capillaries from the pre-existing vasculature plays vital role for the development of therapeutic approaches for cancer, atherosclerosis, wound healing, and cardiovascular diseases. In this report, the synthesis, characterization, and angiogenic properties of graphene oxide (GO) and reduced graphene oxide (rGO) have been demonstrated, observed through several in vitro and in vivo angiogenesis assays. The results here demonstrate that the intracellular formation of reactive oxygen species and reactive nitrogen species as well as activation of phospho-eNOS and phospho-Akt might be the plausible mechanisms for GO and rGO induced angiogenesis. The results altogether suggest the possibilities for the development of alternative angiogenic therapeutic approach for the treatment of cardiovascular related diseases where angiogenesis plays a significant role.

Abstract
Angiogenesis, a process involving the growth of new blood vessels from the pre-existing vasculature, plays a crucial role in various pathophysiological conditions. We have previously demonstrated that europium hydroxide [Eu(III)(OH)3] nanorods (EHNs) exhibit pro-angiogenic properties through the generation of reactive oxygen species (ROS) and mitogen activated protein kinase (MAPK) activation. Considering the enormous implication of angiogenesis in cardiovascular diseases (CVDs) and cancer, it is essential to understand in-depth molecular mechanisms and signaling pathways in order to develop the most efficient and effective alternative treatment strategy for CVDs. However, the exact underlying mechanism and cascade signaling pathways behind the pro-angiogenic properties exhibited by EHNs still remain unclear. Herein, we report for the first time that the hydrogen peroxide (H2O2), a redox signaling molecule, generated by these EHNs activates the endothelial nitric oxide synthase (eNOS) that promotes the nitric oxide (NO) production in a PI3K (phosphoinositide 3-kinase)/Akt dependent manner, eventually triggering angiogenesis. We intensely believe that the investigation and understanding of the in-depth molecular mechanism and signaling pathways of EHNs induced angiogenesis will help us in developing an effective alternative treatment strategy for cardiovascular related and ischemic diseases where angiogenesis plays an important role.

Abstract
BACKGROUND We have previously reported that increased glucose levels were associated with higher serum nitric oxide (NO) levels in fructose-fed insulin resistant rats. However, the relationship between hyperglycemia and serum NO level was not clear. Therefore, the present study was designed to find the association between hyperglycemia and serum NO levels in Type 2 diabetic (T2DM) patients and T2DM with cardiovascular complication. METHODS Endothelial cells (HUVEC) were treated with of D-glucose (10-100mM), and NO levels and NOS gene expression was measured. Hyperglycaemia was induced in Sprague-Dawley rats, and serum NO levels were measured after 8 weeks. For clinical evaluation, five groups of patients were recruited: Control (CT, n=48), Type 2 diabetes (T2DM, n=26), T2DM with hypertension (DMHT, n=46), Coronary artery diseases (CAD, n=29) and T2DM with coronary artery diseases (DMCD, n=38). NO (nitrite + nitrate) levels were measured from human serum. RESULTS We found a significant (p<0.05) and dose-dependent increase in NO levels in HUVEC cells after 4 hours of high glucose exposure. eNOS and iNOS gene expression was increased in HUVEC cells after different concentrations and time periods of glucose treatment. We also observed significant (149.1 ± 25 μM, p<0.01) increase in serum NO levels in hyperglycaemic rats compared to control (76.6 ± 13.2 μM). Serum NO level was significantly higher in T2DM (111.8 μM (81.7-122.4), p<0.001) and DMCD patients ((129.4 μM (121.2-143.5), p <0.001) but not in CAD patients (76.4 μM (70.5-87)), as compared to control (68.2 μM (56.4-82.3)). We found significantly lower NO levels (83.5 μM (60.5-122.9)) in subjects suffering from diabetes since more than 5 years, compared to subjects (115.3 μM (75.2-127.1), p<0.001) with less than 5 years. CONCLUSION In conclusion, high NO levels were observed in South Indian diabetic patients. Higher glucose levels in serum might be responsible for activation of endothelial cells to enhance NO levels.
