Abstract
Millions of cases of dengue virus (DENV) infection yearly from Aedes mosquitoes stress the need for effective antivirals. No current drug effectively combats dengue efficiently. Transient immunity and severe risks highlight the need for broad-spectrum antivirals targeting all serotypes of DENV. Niclosamide, an antiparasitic, shows promising antiviral activity against the dengue virus, but enhancing its bioavailability is challenging. To overcome this issue and enable niclosamide to address the global dengue problem, nanoengineered niclosamides can be the solution. Not only does it address cost issues but also with its broad-spectrum antiviral effects nanoengineered niclosamide offers hope in addressing the current health crisis associated with DENV and will play a crucial role in combating other arboviruses as well.

Abstract
CD27 belongs to the tumor necrosis factor receptor superfamily and acts as a co-stimulatory molecule, modulating T and B cell responses. CD27 stimulation enhances T cell survival and effector functions, thus providing opportunities to develop therapeutic strategies. The current study aims to investigate the role of endogenous CD27 signaling in tumor growth and metastasis. CD8 + T cell-specific CD27 knockout (CD8Cre-CD27fl) mice were developed, while global CD27 knockout (KO) mice were also used in our studies. Flow cytometry analyses confirmed that CD27 was deleted specifically from CD8 + T cells without affecting CD4 + T cells, B cells, and HSPCs in the CD8Cre-CD27fl mice, while CD27 was deleted from all cell types in global CD27 KO mice. Tumor growth and metastasis studies were performed by injecting B16-F10 melanoma cells subcutaneously (right flank) or intravenously into the mice. We have found that global CD27 KO mice succumbed to significantly accelerated tumor growth compared to WT controls. In addition, global CD27 KO mice showed a significantly higher burden of metastatic tumor nests in the lungs compared to WT controls. However, there was no significant difference in tumor growth curves, survival, metastatic tumor nest counts between the CD8Cre-CD27fl mice and WT controls. These results suggest that endogenous CD27 signaling inhibits tumor growth and metastasis via CD8 + T cell-independent mechanisms in this commonly used melanoma model, presumably through stimulating antitumor activities of other types of immune cells.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Rheumatoid arthritis (RA) is a multifactorial, polygenic inflammatory disease. Mesua assamica (King & Prain) Kosterm. (MA) is an endangered medicinal plant indigenous to South Asia, primarily to Assam in India. The tree bark is claimed to possess anti-inflammatory, anti-diabetic, anti-cancer, and anti-malarial properties; nevertheless, its role in RA has not been elucidated. Hence, this study aims to investigate the in-vitro and in-vivo anti-arthritic effects of Mesua assamica bark ethanolic extract (MAE). AIM OF THE STUDY This study aims to investigate the anti-rheumatic potential of MAE in-vitro on RAW 264.7 cells for its anti-oxidant and anti-inflammatory activities and in-vivo on the CFA-induced adjuvant arthritis in the rat model. MATERIALS AND METHODS We investigated the possible therapeutic effects of MAE in-vitro using RAW 264.7 cells triggered by LPS. Meanwhile, adult Wistar rats were injected intradermally with 100 μl of CFA to induce arthritis, and they were given MAE orally at doses of 100 and 200 mg/kg for up to 28 days. Paw volume analysis, X-ray radiography, anti-oxidant levels analysis, gene and protein expression studies, and histological analysis were carried out to assess the effects of MAE in-vivo. RESULTS MAE significantly mitigated the inflammation by reducing ROS levels and dropped the nitrite, PGE2, and COX-2 levels enhanced by LPS in-vitro. At the same time, MAE treatment reduced the paw and joint inflammation and increased the immune organ index in the CFA rats. Histopathology data revealed that MAE mitigated the CFA-induced lesions of the ankle joints and synovial tissues. Similarly, MAE significantly abated the secretion of pro-inflammatory cytokines, inhibited the protein expression of TLR4, NF-кB, COX-2, and iNOS, as well as improved the Nrf2 and HO-1 levels in-vitro and in-vivo. CONCLUSION All the results highlighted the anti-rheumatic potential of MAE in RA in-vitro and in-vivo by inhibiting the TLR4/NF-кB/COX-2/iNOS and promoting the Nrf2/HO-1 signaling axis.

Abstract
Erythropoietin-producing hepatocellular A2 (EphA2) is a vital member of the Eph tyrosine kinase receptor family and has been associated with developmental processes. However, it is often overexpressed in tumors and correlates with cancer progression and worse prognosis due to the activation of its noncanonical signaling pathway. Throughout cancer treatment, the emergence of drug-resistant tumor cells is relatively common. Since the early 2000s, researchers have focused on understanding the role of EphA2 in promoting drug resistance in different types of cancer, as well as finding efficient and secure EphA2 inhibitors. In this review, the current knowledge regarding induced resistance by EphA2 in cancer treatment is summarized, and the types of cancer that lead to the most cancer-related deaths are highlighted. Some EphA2 inhibitors were also investigated. Regardless of whether the cancer treatment has reached a drug-resistance stage in EphA2-overexpressing tumors, once EphA2 is involved in cancer progression and aggressiveness, targeting EphA2 is a promising therapeutic strategy, especially in combination with other target-drugs for synergistic effect. For that reason, monoclonal antibodies against EphA2 and inhibitors of this receptor should be investigated for efficacy and drug toxicity.

Abstract
The tumor microenvironment (TME) plays a pivotal role in cancer development and progression. In this line, revealing the precise mechanisms of the TME and associated signaling pathways of tumor resistance could pave the road for cancer prevention and efficient treatment. The use of nanomedicine could be a step forward in overcoming the barriers in tumor-targeted therapy. Novel delivery systems benefit from enhanced permeability and retention effect, decreasing tumor resistance, reducing tumor hypoxia, and targeting tumor-associated factors, including immune cells, endothelial cells, and fibroblasts. Emerging evidence also indicates the engagement of multiple dysregulated mediators in the TME, such as matrix metalloproteinase, vascular endothelial growth factor, cytokines/chemokines, Wnt/β-catenin, Notch, Hedgehog, and related inflammatory and apoptotic pathways. Hence, investigating novel multitargeted agents using a novel delivery system could be a promising strategy for regulating TME and drug resistance. In recent years, small molecules from natural sources have shown favorable anticancer responses by targeting TME components. Nanoformulations of natural compounds are promising therapeutic agents in simultaneously targeting multiple dysregulated factors and mediators of TME, reducing tumor resistance mechanisms, overcoming interstitial fluid pressure and pericyte coverage, and involvement of basement membrane. The novel nanoformulations employ a vascular normalization strategy, stromal/matrix normalization, and stress alleviation mechanisms to exert higher efficacy and lower side effects. Accordingly, the nanoformulations of anticancer monoclonal antibodies and conventional chemotherapeutic agents also improved their efficacy and lessened the pharmacokinetic limitations. Additionally, the coadministration of nanoformulations of natural compounds along with conventional chemotherapeutic agents, monoclonal antibodies, and nanomedicine-based radiotherapy exhibits encouraging results. This critical review evaluates the current body of knowledge in targeting TME components by nanoformulation-based delivery systems of natural small molecules, monoclonal antibodies, conventional chemotherapeutic agents, and combination therapies in both preclinical and clinical settings. Current challenges, pitfalls, limitations, and future perspectives are also discussed.

Abstract
Ulcerative colitis (UC) is an idiopathic, chronic disorder of the intestines characterized by excessive inflammation and oxidative stress. Loganic acid (LA) is an iridoid glycoside reported to have antioxidant and anti-inflammatory properties. However, the beneficial effects of LA on UC are unexplored yet. Thus, this study aims to explore the potential protective effects of LA and its possible mechanisms. In-vitro models were employed using LPS-stimulated RAW 264.7 macrophage cells, and Caco-2 cells, whereas an in-vivo model of ulcerative colitis was employed using 2.5% DSS in BALB/c mice. Results indicated that LA significantly suppressed the intracellular ROS levels and inhibited the phosphorylation of NF-κB in both RAW 264.7 and Caco-2 cells, contrarily LA activated the Nrf2 pathway in RAW 264.7 cells. In DSS-induced colitis mice, LA significantly alleviated the inflammation and colonic damage by decreasing the pro-inflammatory cytokines (IL-1β, IL-6, TNF-α, and IFN-γ), oxidative stress markers (MDA, and NO), and also expression levels of various inflammatory proteins (TLR4 and NF-кB) which was evidenced by immunoblotting. On the contrary, the release of GSH, SOD, HO-1, and Nrf2 were profoundly increased upon LA treatment.Subsequently, molecular docking studies showed that LA interacts with active site regions of target proteins (TLR4, NF-κB, SIRT1, and Nrf2) through hydrogen bonding and salt bridge interaction. The current findings demonstrated that LA could exhibit a protective effect in DSS-induced ulcerative colitis through its anti-inflammatory and anti-oxidant effects via inactivating the TLR4/NF-κB signaling pathway and activating the SIRT1/Nrf2 pathways.

Abstract
The paper presents the results of the experimental and analytical study of targeted drug-loaded polymer-based microspheres made from blend polymer of polylactic-co-glycolic acid and polycaprolactone (PLGA-PCL) for targeted and localized cancer drug delivery. In vitro sustained release with detailed thermodynamically driven drug release kinetics, over a period of three months using encapsulated targeted drugs (prodigiosin-EphA2 or paclitaxel-EphA2) and control drugs [Prodigiosin (PGS), and paclitaxel (PTX)] were studied. Results from in vitro study showed a sustained and localized drug release that is well-characterized by non-Fickian Korsmeyer-Peppas kinetics model over the range of temperatures of 37 °C (body temperature), 41 °C, and 44 °C (hyperthermic temperatures). The in vitro alamar blue, and flow cytometry assays in the presence of the different drug-loaded polymer formulations resulted to cell death and cytotoxicity that was evidence through cell inhibition and late apoptosis on triple negative breast cancer (TNBC) cells (MDA-MB 231). In vivo studies carried out on groups of 4-week-old athymic nude mice that were induced with subcutaneous TNBC, showed that the localized release of the EphA2-conjugated drugs was effective in complete elimination of residual tumor after local surgical resection. Finally, ex vivo histopathological analysis carried out on the euthanized mice revealed no cytotoxicity and absence of breast cancer metastases in the liver, kidney, and lungs 12 weeks after treatment. The implications of the results are then discussed for the development of encapsulated EphA2-conjugated drugs formulation in the specific targeting, localized, and sustain drug release for the elimination of local recurred TNBC tumors after surgical resection.

Abstract
Accumulating evidence attributes the role of aldose reductase (AR) in modulating ROS and inflammation which are the main factor responsible for cancer progression and drug resistance. Epalrestat is the only AR inhibitor being used in Asian countries. It did not make it to the markets of the USA and Europe due to marginal efficacy as an antioxidant and anti-inflammatory agent owing to difficulty reaching intracellular targets. In our previous studies, we attempted to synthesize the epalrestat analogs and reported that the compound 4-((Z)-5-((Z)-2-Cyano-3-phenylallylidene)-4-oxo-2-thioxothiazolidin-3-yl) benzoic acid named as NARI-29 has potent AR inhibition compared to epalrestat. In the current study, we aimed to find the effect of NARI-29 on ROS-induced cancer progression and TRAIL resistance in colon cancer in vitro models. In the first part of the study, we demonstrated that the NARI-29 has specific AKR1B1 inhibition and superior drug-like properties than epalrestat using bioinformatics tools. In the second part of the study, it was proven that NARI-29 has induced the hydrogen peroxide-triggered TRAIL-induced apoptosis in the colon cancer cells via modulating the AKR1B1/4HNE/FOXO3a/DR axis. The selective cytotoxicity of NARI-29 (10-fold) compared to epalrestat (4-fold) toward cancer cells is due to its differential ROS regulation and anti-inflammatory activities. Altogether, these data show that NARI-29 may be a potential candidate for AR inhibitors, which will be used to prevent colon cancer progression and as adjuvant therapy for preventing TRAIL resistance.

Abstract
Long-term oral tofacitinib (TOF) administration has been linked to serious side effects majorly immunological suppression. The aim of this work was to enhance the therapeutic efficacy of TOF by chondroitin sulphate (CS) coated proglycosomes through the anchoring of high-affinity CS to CD44 receptors on immune cells in the inflammatory region. The CS was coated onto the TOF-loaded proglycosomes (CS-TOF-PG) formulations and they were evaluated for in vitro drug release, ex vivo (permeation, dermatokinetics) studies. In vivo efficacy studies were carried out in Freund's complete adjuvant (CFA) induced arthritis model. The optimized CS-TOF-PG showed particle sizes of 181.13 ± 7.21 nm with an entrapment efficiency of 78.85 ± 3.65 %. Ex-vivo studies of CS-TOF-PG gel exhibited 1.5-fold high flux and 1.4-fold dermal retention compared to FD-gel. The efficacy study revealed that CS-TOF-PG showed a significant (P < 0.001) reduction in inflammation in arthritic rat paws compared to the TOF oral and FD gel. The current study ensured that the CS-TOF-PG topical gel system would provide a safe and effective formulation for localization and site-specific delivery of TOF at the RA site and overcome the adverse effects associated with the TOF.

Abstract
BACKGROUND AND OBJECTIVE Many naturally available dietary molecules such as curcumin have not seen the market due to poor solubility, bioavailability, and photodegradability. Successful development of a lipid-based dry emulsion may overcome these issues and help in reaching the markets for natural dietary molecules such as curcumin. The current study aims to develop a dry emulsion formulation of curcumin using natural oil and evaluate its dissolution, photostability, pharmacokinetics, and anti-inflammatory activity. METHODS Dry emulsions were prepared using emu oil and corn oil as the lipid phase, Caproyl 90 and Cremophor RH 40 as surfactants, and dextrin as a hydrophilic carrier. RESULTS Microscopic studies showed the formation of spherical porous particles, and solid-state characterization using differential scanning calorimetry and powder X-ray diffraction showed the conversion of curcumin to an amorphous form. About 80% drug release was observed from formulation, whereas pure drug showed only 50% drug release in 30 min. In vivo pharmacokinetic studies showed fivefold improvement in the maximum concentration of curcumin in plasma (Cmax) and sevenfold improvement in the area under the concentration-time curve of curcumin from emu oil formulation compared with pure curcumin. Significant differences were observed in the anti-inflammatory activity of curcumin dry emulsion and plain curcumin. Emu-oil-based formulations showed synergistic anti-inflammatory activity over corn-oil-based formulations with improved photostability. CONCLUSION The present study suggests that the dry emulsion may enhance the bioavailability with synergistic anti-inflammatory activity and photostability of curcumin when given orally.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Mesua Assamica (King & prain) Kosterm. (MA) is an evergreen endemic medicinal tree available in Assam in India and other parts of south Asia. The bark of the plant is traditionally used for ant-malarial activity and treating fevers. It was reported to have anti-oxidant, anti-inflammatory, anti-diabetic, anti-cancer and anti-malarial properties, but no research findings have been reported about its protective activity on intestinal inflammatory disorders like ulcerative colitis (UC) yet. AIM OF THE STUDY The aim of the current study is to evaluate the anti-ulcerative property of ethanolic extract of MA (MAE) in-vitro on GloResponse™ NF-кB-RE-luc2P HEK 293 cells for its anti-oxidant and anti-inflammatory activities and in-vivo chronic restraint stress aggravated dextran sodium sulfate (DSS)-induced UC model. MATERIALS AND METHODS The chemical constituents of MAE were identified by LC-MS/MS. The in-vitro effects of MAE on GloResponse™ NF-кB-RE-luc2P HEK 293 cells stimulated with TNF-α 30 ng/ml were investigated for its potential therapeutic effects. Parameters such as body weights, behavioural, colonoscopy, colon lengths and spleen weights were measured and recorded in chronic restraint stress aggravated DSS-induced UC model in C57BL/6 mice. Histological, cytokines and immunoblotting analysis in the colon tissues were determined to prove its anti-inflammatory and anti-oxidant activities. RESULTS MAE poses significant anti-oxidant and anti-inflammatory activity in-vitro in GloResponse™ NF-кB-RE-luc2P HEK 293 cells evidenced by DCFDA and immunoflourescence assay. MAE treatment at 100 mg/kg and 200 mg/kg for 14 consecutive days has reduced Disease activity Index (DAI), splenomegaly and improved the shortened colon length and sucrose preference in mice. MAE treatment has increased the levels of anti-oxidants like GSH and reduced the levels of MDA, MPO and nitrite levels in colon tissues. Moreover, MAE has ameliorated neutrophil accumulation, mucosal and submucosal inflammation and crypt density evidenced by histopathology. Furthermore, MAE treatment significantly reduced the increased pro-inflammatory cytokines like IL-6, IL-1β and TNF-α. we found from immunoblotting that there is a concomitant decrease in protein expression of NF-κB, STAT3 signalling cascades and phosphorylation of IKBα with an increase in Nrf2, SOD2, HO-1 and SIRT1 in colon tissues. In addition, we have performed molecular docking studies confirming that phytochemicals present in the MAE have a stronger binding ability and druggability to the NF-κB, Nrf2 and SIRT1 proteins. CONCLUSIONS MAE exhibited significant anti-colitis activity on chronic restraint stress aggravated DSS-induced ulcerative colitis via regulating NF-κB/STAT3 and HO-1/Nrf2/SIRT1 signaling pathways.

Abstract
BACKGROUND Ulcerative colitis (UC) is the most prevalent chronic inflammatory immune bowel disease. The modernization of lifestyle accompanied by the stress to cope with the competition has resulted in a new range of complications where stress became a critical contributing factor for many diseases, including UC. Hence there is an urgent need to develop a dual role in curtailing both systemic and neuroinflammation. Perillyl alcohol (POH) is a natural essential oil found in lavender, peppermint, cherries etc and has been widely studied for its strong anti-inflammatory, antioxidant and anti-stress properties. HYPOTHESIS/PURPOSE POH regulates the various inflammatory signaling cascades involved in chronic inflammation by inhibiting farnesyltransferase enzyme. Several studies reported that POH could inhibit the phosphorylation of NF-κB, STAT3 and promote the endogenous antioxidant enzymes like Nrf2 via farnesyltransferase enzyme inhibition. Also, the effects of POH against UC is not known yet. Thus, this study aims to explore the anti-ulcerative properties of POH on stress aggravated ulcerative colitis in C57BL/6 mice. METHODS Ulcerative colitis was induced by duel exposure of chronic restraint stress (day 1 to day 28) and 2.5% dextran sulphate sodium (day8 to day14) in mice. POH treatment 100 and 200 mg/kg was administred from day14 ti day28 following oral route of administration. Disease activity index, colonoscopy, western blot analysis and histological analysis, neurotransmitter analysis and Gene expression studies were perofomerd to asses the anti-colitis effects of POH. RESULTS The treatment reversed the oxidative stress and inflammatory response by inhibiting TLR4/NF-kB pathway, and IL-6/JAK2/STAT3 pathway in both isolated mice colons and brains. The inhibition of these pathways resulted in a decrease in pro-inflammatory cytokines like IL-6, IL-1β and TNF-α. The treatment improved the physiological and histological changes with decreased ulcerations as examined by colonic endoscopy and Haematoxylin and Eosin staining. The treatment also improved the behavior response as it increased mobility time which was reduced by chronic restrained stress. This was due to increased satiety neurotransmitters like dopamine and serotonin and decreased cortisol in mice brains. CONCLUSION These results infer that POH has significant anti-colitis activity on chronic restraint stress aggravated DSS-induced UC in mice.

Abstract
Melanoma is the most malignant form of skin cancer across the globe. Conventional therapies are currently ineffective which could be attributed to the rampant chemo-resistance, metastasis, inability to cross the skin barriers and accumulate within the tumor microenvironment. This advent brings in the principles of drug repurposing by repositioning Niclosamide (NIC), an anthelmintic drug for skin cancer. Incorporation into the liposomes facilitated enhanced melanoma cell uptake and apoptosis. Cytotoxicity studies revealed 1.756-fold enhancement in SK-MEL-28 cytotoxicity by NIC-loaded liposomes compared to free drug. Qualitative and quantitative cell internalization indicated greater drug uptake within the melanoma cells illustrating the efficacy of liposomes as efficient carrier systems. Nuclear staining showed blebbing and membrane shrinkage. Elevated ROS levels and apoptosis shown by DCFDA and acridine orange-ethidium bromide staining revealed greater melanoma cell death by liposomes compared to free drug. Incorporating NIC liposomes into the thermogel system restricted the liposomes as a depot onto the upper skin layers. Sustained zero order release up to 48 h with liposomes and 23.58-fold increase in viscosity led to the sol-to-gel transition at 33℃ was observed with liposomal thermogel. Ex vivo gel permeation studies revealed that C-6 loaded liposomes incorporated within the thermogel successfully formed a depot over the upper skin layer for 6 h to prevent transdermal delivery and systemic adverse effects. Thus, it could be concluded that NIC loaded liposomal thermogel system could be an efficacious therapeutic alternative for the management of melanoma.

Abstract
Among the diverse protein binding modules, Sam (Sterile alpha motif) domains attract attention due to their versatility. They are present in different organisms and play many functions in physiological and pathological processes by binding multiple partners. The EphA2 receptor contains a Sam domain at the C-terminus (EphA2-Sam) that is able to engage protein regulators of receptor stability (including the lipid phosphatase Ship2 and the adaptor Odin). Ship2 and Odin are recruited by EphA2-Sam through heterotypic Sam-Sam interactions. Ship2 decreases EphA2 endocytosis and consequent degradation, producing chiefly pro-oncogenic outcomes in a cellular milieu. Odin, through its Sam domains, contributes to receptor stability by possibly interfering with ubiquitination. As EphA2 is upregulated in many types of tumors, peptide inhibitors of Sam-Sam interactions by hindering receptor stability could function as anticancer therapeutics. This review describes EphA2-Sam and its interactome from a structural and functional perspective. The diverse design strategies that have thus far been employed to obtain peptides targeting EphA2-mediated Sam-Sam interactions are summarized as well. The generated peptides represent good initial lead compounds, but surely many efforts need to be devoted in the close future to improve interaction affinities towards Sam domains and consequently validate their anticancer properties.

Abstract
Bellidifolin (BEL), a xanthone compound, has significant therapeutic effectiveness in cardiac diseases such as arrhythmias. However, BEL is limited in clinical applications by its hydrophobicity. In this work, we used BEL as the active pharmaceutical ingredient (API), and polyethylene glycol 15-hydroxy stearate (Kolliphor HS15) as the carrier to prepare BEL nano-micelles by a solvent-volatilization method. According to an analysis by differential scanning calorimetry (DSC), BEL was successfully encapsulated in HS15 as BEL nano-micelles with a 90% encapsulation rate, and particle size was 12.60 ± 0.074 nm in the shape of a sphere and electric potential was −4.76 ± 4.47 mV with good stability and sustained release characteristics. In addition, compared with free drugs, these nano-micelles can increase cellular uptake capacity, inhibit the proliferation of human cardiac fibroblasts, and down-regulate the expression of Smad-2, α-SMA, Collagen I, and Collagen III proteins in myocardial cells to improve myocardial fibrosis. In conclusion, the BEL nano-micelles can provide a new way for the theoretical basis for the clinical application of anti-cardiac fibrosis. Bellidifolin (BEL), a xanthone compound, has significant therapeutic effectiveness in cardiac diseases such as arrhythmias.![]()

Chitosan IR806 dye-based polyelectrolyte complex nanoparticles with mitoxantrone combination for effective chemo-photothermal therapy of metastatic triple-negative breast cancer. Int J Biol Macromol 2022; 216:558-570.

Abstract
Chemo-photothermal therapy is one of the emerging therapies for treating triple-negative breast cancer. In this study, we have used ionotropic gelation method to fabricate chitosan and IR806 dye-based polyelectrolyte complex (CIR-PEx) nanoparticles. These nano-complexes were in size range of 125 ± 20 nm. The complexation of IR 806 dye with chitosan improved photostability, photothermal transduction, and showed excellent biocompatibility. Cancer cells treated with CIR-PEx NPs enhanced intracellular uptake within 5 h of incubation and also displayed mitochondrial localization. With the combination of CIR-PEx NPs and a chemotherapeutic agent (i.e., mitoxantrone, MTX), a significant decline in cancer cell viability was observed in both 2D and 3D cell culture models. The chemo-photothermal effect of CIR-PEx NPs + MTX augmented apoptosis in cancer cells when irradiated with NIR light. Furthermore, when tested in the 4 T1-tumor model, the chemo-photothermal therapy showed a drastic decline in tumor volume and inhibited metastatic lung nodules. The localized hyperthermia caused by photothermal therapy reduced the primary tumor burden, and the chemotherapeutic activity of mitoxantrone further complemented by inhibiting the spread of cancer cells. The proposed chemo-photothermal therapy combination could be a promising strategy for treating triple-negative metastatic breast cancer.

Abstract
BACKGROUND Rheumatoid arthritis is a chronic and idiopathic autoimmune disorder. Perillyl alcohol (POH) is a monoterpene which can be extracted from widely available essential oils and is known for its strong anti-inflammatory and anti-oxidant properties. HYPOTHESIS/PURPOSE Recent studies have been proven that inhibitors of farnesyltransferase enzyme showed significant anti-arthritic activity. POH is one such natural molecule having anti-inflammatory and anti-oxidant properties by inhibiting farnesyltransferase enzyme which further down regulates NF-κB and Nrf2 via Ras/Raf/MAPK pathway. Also, the effect of POH against rheumatoid arthritis is not known yet. Hence, the present research was intended to assess the anti-arthritic potential of POH in-vitro and in-vivo. METHODS The in-vitro effects of POH on RAW 264.7 cells stimulated with LPS 1 µg/ml were investigated to its potential therapeutic effects. CFA 100 µl was intradermally administered to rats for the induction of arthritis. POH 100 mg/kg and 200 mg/kg administered topically from day 1 to day 28. Paw volumes measured, radiography analysis, anti-oxidant status, Gene expression studies, western blot analysis and histological analysis were performed to check the effects of POH. RESULTS Our in-vitro findings suggested that POH inhibits inflammation by suppressing reactive oxygen species (ROS), NF-кB and Nrf2 signaling axis. Besides this, POH also rescinded the nitrate levels, pro-inflammatory cytokine levels like IL-1β, IL-6 and TNF-α also PGE2 and COX-2 levels induced by LPS in murine macrophages. Additionally, our in-vivo results revealed that POH conscientiously alleviated CFA induced inflammation by restoring arthritis index, body weight, nitrosative, lipid peroxidation assays. Macroscopically through measuring paw volumes and X-ray, it was evidenced that POH has decreased inflammation and bone erosion. Not only in-vitro but also in-vivo, POH has abridged cytokine levels IL-1β, IL-6, and TNF-α. Histopathological evaluation presented POH treatment alleviated joint inflammation, pannus formation, and bone erosion significantly. Moreover, POH suppressed the protein expression of NF-кB, COX-2, iNOS and improved Nrf2, and SOD2 levels in paw tissues estimated by western blotting. CONCLUSION POH was effective in ameliorating LPS stimulation mediated oxidative stress and pro-inflammatory cytokines in RAW 264.7 cells in-vitro and FCA induced arthritis in rats in-vivo through its anti-inflammatory effects via regulating TLR4/NF-κB and Keap1/Nrf2 signaling pathways..

Abstract
As per the WHO, every year around 2.1 million women are detected with breast cancer. It is one of the most invasive cancer in women and second most among all, contributing around 15% of death worldwide. The available anticancer therapies including chemo, radio, and hormone therapy are associated with a high load of reversible and irreversible adverse effects, limited therapeutic efficacy, and low chances of quality survival. To minimize the side effects, improving therapeutic potency and patient compliance promising targeted therapies are highly desirable. In this sequence, various nanocarriers and target modified systems have been explored by researchers throughout the world. Among these chitosan-based nanocarriers offers one of the most interesting, flexible, and biocompatible systems. The unique characteristics of chitosan like surface flexibility, biocompatibility, hydrophilicity, non-toxic and cost-effective behavior assist to overcome the inadequacy of existing therapy. The present review throws light on the successes, failures, and current status of chitosan modified novel techniques for tumor targeting of bioactives. It also emphasizes the molecular classification of breast cancer and current clinical development of novel therapies. The review compiles most relevant works of the past 10 years focusing on the application of chitosan-based nanocarrier against breast cancer.

Abstract
Retinoblastoma (Rb) is the most critical and severe intraocular malignancy occurring in children. The clinical management of retinoblastoma is still challenging due to failure in early detection and control despite the advancements in medical strategies. Early-stage Rb tumors do not occupy major visual fields, so chemo/photothermal therapy (PTT) with biocompatible materials can be a practical approach. Herein, we report multifunctional polymeric nanoparticles (PNPs) entrapped with an FDA-approved anticancer drug, Palbociclib (PCB), and a near-infrared dye, IR820 (IR), as chemo/photothermal agents. These PCB/IR PNPs were evaluated for the combinational effect in the retinoblastoma cell line. Further, the in vivo photoacoustic imaging efficacy and acute toxicity profile of the PNPs were studied in a mice model. The results indicated that the PCB/IR PNPs exhibited a significant cytotoxic effect (86.5 ± 2.3%) in Y79 cell lines than the respective control groups upon exposure to NIR light. Qualitative and quantitative analyses indicated that PCB/IR PNPs with NIR light induction resulted in DNA damage followed by apoptosis. PCB/IR PNPs, when tested in vivo, showed optimal photoacoustic signals. Thus, the combination of PCB and PTT can emerge as a translational modality for retinoblastoma therapy.

Perillyl alcohol inhibits keratinocyte proliferation and attenuates imiquimod-induced psoriasis like skin-inflammation by modulating NF-κB and STAT3 signaling pathways. Int Immunopharmacol 2021; 103:108436. [PMID: 34929480 DOI: 10.1016/j.intimp.2021.108436] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/23/2021] [Revised: 11/23/2021] [Accepted: 12/03/2021] [Indexed: 01/05/2023]
Abstract
Psoriasis is a chronic inflammatory and proliferative skin disease characterized by pathological skin lesions which significantly impact the quality of life. Recent studies have been proven that inhibitors of farnesyltransferase enzyme showed significant anti-psoriatic activity. Perillyl alcohol (POH) is one such natural molecule having anti proliferative, anti-inflammatory and anti-oxidant properties by inhibiting farnesyltransferase enzyme which further down regulates NF-κB and STAT3 via Ras/Raf/MAPK pathway. Hence, in the current study we aimed to find the effect of POH on human keratinocytes (HaCat) cells in in-vitro and IMQ induced psoriatic like skin inflammation model in mice. POH significantly decreased the intracellular ROS levels and inhibited the phosphorylation of NF-κB and STAT3 in in-vitro. It was found that POH (200 mg/kg, topical application) has reduced the epidermal hyperplasia, psoriasis area and severity index (PASI) scoring; splenomegaly in imiquimod (IMQ) induced psoriatic mice. Further, POH treatment has decreased the pro-inflammatory serum cytokine levels such as IL-6, IL-12/23, TNF-α and IL-1β and also reduced the expression levels of various inflammatory proteins, COX-2, iNOS, IL-17A, IL-22, NF-кB and STAT3 evidenced by Immunoblotting studies from skin samples. The levels of endogenous antioxidants like glutathione GSH, SOD, Nrf2 were restored to normal levels upon POH treatment. POH downregulated the proteins levels of TLR7, TLR8, CyclinD1 and mRNA expression of Bcl-2 in the skin samples when compared to the IMQ group. POH has ameliorated the hyper-keratosis and acanthosis which was evidenced by histopathology. Collectively, our results suggest that POH has a promising therapeutic application for ameliorating psoriasis-like skin inflammation.
