Federated Learning Survival Model and Potential Radiotherapy Decision Support Impact Assessment for Non-small Cell Lung Cancer Using Real-World Data

AIMS

The objective of this study was to develop a two-year overall survival model for inoperable stage I-III non-small cell lung cancer (NSCLC) patients using routine radiation oncology data over a federated (distributed) learning network and evaluate the potential of decision support for curative versus palliative radiotherapy.

METHODS

A federated infrastructure of data extraction, de-identification, standardisation, image analysis, and modelling was installed for seven clinics to obtain clinical and imaging features and survival information for patients treated in 2011-2019. A logistic regression model was trained for the 2011-2016 curative patient cohort and validated for the 2017-2019 cohort. Features were selected with univariate and model-based analysis and optimised using bootstrapping. System performance was assessed by the receiver operating characteristic (ROC) and corresponding area under curve (AUC), C-index, calibration metrics and Kaplan-Meier survival curves, with risk groups defined by model probability quartiles. Decision support was evaluated using a case-control analysis using propensity matching between treatment groups.

RESULTS

1655 patient datasets were included. The overall model AUC was 0.68. Fifty-eight percent of patients treated with palliative radiotherapy had a low-to-moderate risk prediction according to the model, with survival times not significantly different (p = 0.87 and 0.061) from patients treated with curative radiotherapy classified as high-risk by the model. When survival was simulated by risk group and model-indicated treatment, there was an estimated 11% increase in survival rate at two years (p < 0.01).

CONCLUSION

Federated learning over multiple institution data can be used to develop and validate decision support systems for lung cancer while quantifying the potential impact of their use in practice. This paves the way for personalised medicine, where decisions can be based more closely on individual patient details from routine care.

Correlation of salivary cytokine IL-17A and 1,25 dihydroxycholecalciferol in patients undergoing orthodontic treatment

The management of malocclusion has developed greatly in terms of treatment simulation and biomechanics, but treatment duration has been a great concern to the clinician as well as the patient. 1-25dihydroxycholecalciferol (biologically active form of Vitamin D) stimulates both osteoclasts and osteoblasts and was found to be the most significant in Orthodontic Tooth Movement acceleration. Inflammatory cytokines like IL-17A also play an important role in osteoclastogenesis and can enhance the rate of Orthodontic Tooth Movement.To perform a simultaneous evaluation of pro-inflammatory salivary cytokine IL-17A and salivary 1-25dihydroxycholecalciferol and to correlate their role on orthodontic tooth movement.A prospective cohort study was conducted among n = 97 patients. Saliva samples were collected from the patients at three phases of the orthodontic treatment, centrifuged and stored at 4℃ for evaluation of salivary 1-25dihydroxycholecalciferol levels and Pro-inflammatory cytokine IL-17A using ELISA.The mean salivary 1-25dihydoxycholecalciferol levels were 41.250 ng/ml, 33.246 ng/ml and 35.043 ng/ml during the initial phase, lag phase and post lag phase of orthodontic treatment. The mean pro-inflammatory cytokine IL-17 A levels were 107.79 pg/ml, 102.98 pg/ml and 66.156 pg/ml during the initial phase, lag phase and post lag phase of orthodontic treatment. There was a correlation between the salivary 1-25dihydroxycholecalciferol level and salivary cytokine IL-17A levels during the various phases of orthodontic treatment using Spearman's correlation rho test and linear regression analysis. There was no significant difference (p > 0.05) between 1-25dihydroxycholecalciferol levels and gender during the various phases (initial phase, lag phase and post lag phase) of Orthodontic treatment.There was a negative correlation between salivary 1-25dihydroxycholecalciferol level and salivary cytokine IL-17A levels during the various phases of orthodontic treatment. The level of 1-25dihydroxycholecalciferol and salivary cytokine IL-17A have been quantified during the various phases of Orthodontic treatment and this can be used clinically for the supplementation of Vitamin D in patients with low vitamin D levels and can enhance the treatment duration for the patient with less damaging effects to the surrounding tissues.

Design, Synthesis and In Vitro Evaluation of Levodopa Stearic Acid Hydrazide Conjugate for the Management of Parkinson's DiseaseNovel Conjugate for Parkinson's Disease

Parkinson's disease is the highest prevalent neurodegenerative disease in elderly individuals after Alzheimer's disease. The pathological identification for Parkinson's disease is loss of dopaminergic neurons in substantia nigra region of the brain that in turn leads to dopamine deficiency that affects the body's normal physiological and neurological disorder. The important drawback in the modality of treatment is levodopa is only supplying depleted dopamine in the brain, it does not affect neurodegeneration. Even though levodopa manages the disease, an alternative treatment strategy is required to stop or prevent further degeneration of neuron. The compound with neuroprotector activity suits the requirement. Of them, stearic acid plays a vital role in protecting neurons against oxidative stress through a Phosphoinositide 3-kinase-dependent mechanism. Hence, our present study aimed to design, synthesize, and characterize the levodopa stearic acid hydrazide conjugate. Additionally, evaluate the cytotoxicity of synthesized compound in SHSY5Y: cell lines. In brief, levodopa was conjugated to the stearic acid successfully and was confirmed with Fourier-transform infrared spectroscopy, Nuclear magnetic resonance, and Mass Spectroscopy. In vitro cell viability study in SHSY5Y: cell lines showed elevated cell viability in 0.134 µm concentration of Conjugate, and 0.563 µm concentration of levodopa. Showing that the synthesized compound could offer an improved treatment strategy for Parkinson's disease.

Vitamin D analog calcitriol for breast cancer therapy; an integrated drug discovery approach

As breast cancer remains leading cause of cancer death globally, it is essential to develop an affordable breast cancer therapy in underdeveloped countries. Drug repurposing offers potential to address gaps in breast cancer treatment. Molecular networking studies were performed for drug repurposing approach by using heterogeneous data. The PPI networks were built to select the target genes from the EGFR overexpression signaling pathway and its associated family members. The selected genes EGFR, ErbB2, ErbB4 and ErbB3 were allowed to interact with 2637 drugs, leads to PDI network construction of 78, 61, 15 and 19 drugs, respectively. As drugs approved for treating non cancer-related diseases or disorders are clinically safe, effective, and affordable, these drugs were given considerable attention. Calcitriol had shown significant binding affinities with all four receptors than standard neratinib. The RMSD, RMSF, and H-bond analysis of protein-ligand complexes from molecular dynamics simulation (100 ns), confirmed the stable binding of calcitriol with ErbB2 and EGFR receptors. In addition, MMGBSA and MMP BSA also affirmed the docking results. These in-silico results were validated with in-vitro cytotoxicity studies in SK-BR-3 and Vero cells. The IC50 value of calcitriol (43.07 mg/ml) was found to be lower than neratinib (61.50 mg/ml) in SK-BR-3 cells. In Vero cells the IC50 value of calcitriol (431.05 mg/ml) was higher than neratinib (404.95 mg/ml). It demonstrates that calcitriol suggestively downregulated the SK-BR-3 cell viability in a dose-dependent manner. These implications revealed calcitriol has shown better cytotoxicity and decreased the proliferation rate of breast cancer cells than neratinib.Communicated by Ramaswamy H. Sarma.

The identification of cianidanol as a selective estrogen receptor beta agonist and evaluation of its neuroprotective effects on Parkinson's disease models

AIM

The present study aims to identify selective estrogen receptor beta (ERβ) agonists and to evaluate the neuroprotective mechanism in Parkinson's disease (PD) models.

MAIN METHODS

In-silico studies were carried out using Maestro and GROMACS. Neuroprotective activity and apoptosis were evaluated using cytotoxicity assay and flow cytometry respectively. Gene expression studies were carried out by reverse transcription polymerase chain reaction. Motor and cognitive functions were assessed by actophotometer, rotarod, catalepsy, and elevated plus maze. The neuronal population in the substantia nigra and striatum of rats was assessed by hematoxylin and eosin staining.

KEY FINDINGS

Cianidanol was identified as a selective ERβ agonist through virtual screening. The cianidanol-ERβ complex is stable during the 200 ns simulation and was able to retain the interactions with key amino acid residues. Cianidanol (25 μM) prevents neuronal toxicity and apoptosis induced by rotenone in differentiated SH-SY5Y cells. Additionally, cianidanol (25 μM) increases the expression of ERβ, cathepsin D, and Nrf2 transcripts. The neuroprotective effects of cianidanol (25 μM) were reversed in the presence of a selective ERβ antagonist. In this study, we found that selective activation of ERβ could decrease the transcription of α-synuclein gene. Additionally, cianidanol (10, 20, 30 mg/kg, oral) improves the motor and cognitive deficit in rats induced by rotenone.

SIGNIFICANCE

Cianidanol shows neuroprotective action in PD models and has the potential to serve as a novel therapeutic agent for the treatment of PD.

Leveraging decagonal in-silico strategies for uncovering IL-6 inhibitors with precision

Interleukin-6 upregulation leads to various acute phase reactions such as local inflammation and systemic inflammation in many diseases like cancer, multiple sclerosis, rheumatoid arthritis, anemia, and Alzheimer's disease stimulating JAK/STAT3, Ras/MAPK, PI3K-PKB/Akt pathogenic pathways. Since no small molecules are available in the market against IL-6 till now, we have designed a class of small bioactive 1,3 - indanedione (IDC) molecules for inhibiting IL-6 using a decagonal approach computational studies. The IL-6 mutations were mapped in the IL-6 protein (PDB ID: 1ALU) from thorough pharmacogenomic and proteomics studies. The protein-drug interaction networking analysis for 2637 FFDA-approved drugs with IL-6 protein using Cytoscape software showed that 14 drugs have prominent interactions with IL-6. Molecular docking studies showed that the designed compound IDC-24 (-11.8 kcal/mol) and methotrexate (-5.20) bound most strongly to the 1ALU south asian population mutated protein. MMGBSA results indicated that IDC-24 (-41.78 kcal/mol) and methotrexate (-36.81 kcal/mol) had the highest binding energy when compared to the standard molecules LMT-28 (-35.87 kcal/mol) and MDL-A (-26.18 kcal/mol). These results we substantiated by the molecular dynamic studies in which the compound IDC-24 and the methotrexate had the highest stability. Further, the MMPBSA computations produced energies of -28 kcal/mol and -14.69 kcal/mol for IDC-24 and LMT-28. KDeep absolute binding affinity computations revealed energies of -5.81 kcal/mol and -4.74 kcal/mol for IDC-24 and LMT-28 respectively. Finally, our decagonal approach established the compound IDC-24 from the designed 1,3-indanedione library and methotrexate from protein drug interaction networking as suitable HITs against IL-6.

Repurposing of FDA Approved Drugs and Neuropep peptides as Anticancer Agents Against ErbB1 and ErbB2

ErbB1 and ErbB2 are the most important biological targets in cancer drug discovery and development of dual inhibitors for the cancer therapy. FDA approved drugs and Neuropep peptides were used to fit into the ATP binding site of the tyrosine kinases; ErbB1 and ErbB2 proteins. Cytoscape, iGEMDOCK, HPEPDOCK and DataWarrior softwares were used to study the role of these agents as anticancer drugs. Eleven FDA approved drugs and eleven Neuropep peptides showed the strongest 2D interactions and significant binding energy with the proteins. Invitro MTT anticancer assay revealed that, the test compounds, peptide YSFGL and doxorubicin showed significant IC₅₀ value (µM) of 26.417±0.660 and 7.675±0.278 respectively which are compared with the lapatinib standard IC₅₀ value (µM) of 2.380±0.357 against A549 cells and IC₅₀ value (µM) of 39.047±0.770 and 8.313±0.435 respectively which are compared with the lapatinib standard IC₅₀ value (µM) of 3.026±0.180 against MDA-MB-231 cells.

Thioredoxin Interacting Protein Inhibitors In Diabetes Mellitus: A Critical Review

Diabetes Mellitus (DM)is one of the highest contributors to global mortality, exceeding numbers of even the three major infectious diseases in the world, namely Tuberculosis, HIV AIDS, and Malaria. DM is characterised by increased serum levels of glucose caused by a loss of beta cells of the pancreatic islets, responsible for the secretion of insulin. Upon accumulation of data via a wide array of literature surveys, it has been found that Thioredoxin Interacting Protein (TXNIP)presents itself as a vital factor in controlling the production and loss of beta islet cells. TXNIP inhibits the action of the Thioredoxin [TRX] protein found in the beta cells thereby rendering it ineffective in maintaining the cellular redox balance causing oxidative stress and subsequent consequences ultimately leading to aggravation of the disease. TRX exists in the form of two isoforms - TRX1, which is located in the cytosol and at times translocate to the nucleus, and TRX2, which is located in the nucleus. TRX is responsible for the maintenance of the normal cellular redox balance by reducing the oxidised proteins formed by the Reactive Oxygen Species (ROS)with the help of NADPH dependant TRX Reductase enzyme. This proves to be essential in the pathogenesis of Diabetes Mellitus as the beta cells of the pancreatic islets lack a sufficient amount of antioxidant systems. Thus, inhibition of TXNIP has become essential in the survival of beta cells, not only enhancing insulin secretion and sensitivity but also alleviating the diseases associated with Diabetes. Hence, TXNIP is discovered to be a unique therapeutic target in the management of DM.

Metal-Organic Framework in Pharmaceutical Drug Delivery

Metal-organic frameworks (MOFs) are porous, crystalline materials made up of organic ligands and metal ions/metal clusters linked by coordinative bonds. This large family is becoming increasingly popular for drug delivery due to their tuneable porosity, chemical composition, size and shape, and ease of surface functionalization. There has been a growing interest over the last decades in the design of engineered MOFs with controlled sizes for a variety of biomedical applications. Starting with the MOFs classification adapted for drug delivery systems (DDSs) based on the types of constituting metals and ligands. MOFs are appealing drug delivery vehicles because of their substantial drug absorption capacity and slow-release processes, which protect and convey sensitive drug molecules to target areas. Other guest materials have been incorporated into MOFs to create MOF-composite materials, which have added additional functionalities such as externally triggered drug release, improved pharmacokinetics, and diagnostic aids. Magnetic nanoparticles in MOFs for MRI image contrast and polymer coatings that increase blood circulation time are examples of synthetically adaptable MOF-composites. By including photosensitizers, which exert lethal effects on cancer cells by converting tumour oxygen into reactive singlet oxygen (1O2), metal-organic frameworks have been employed for photodynamic treatment (PDT) of malignancies among a multitude of nanosized therapies. Importantly, a variety of representative MOF applications are described from the perspectives of pharmaceutics, disease therapy, and advanced drug delivery systems. However, because of their weak conductivity, selectivity, and lack of modification sites, MOF materials' uses in electrochemical biosensing are restricted. MOF-based composites provide excellent electrical conductivity and robust catalytic activity by adding functionalized nanoparticles into MOF structures, which process benefits over single component MOFs.

Effect of Calcitriol in Inhibiting the Cancer Cell Growth and Promoting Apoptosis in ErbB2-positive Breast Cancer Cells

BACKGROUND

Targeted therapies, specifically ErbB family tyrosine kinase inhibitors, have demonstrated potential for improving outcomes in patients with ErbB2-positive breast cancer. Despite their effectiveness, these therapies are associated with limitations, including high costs, side effects, drug resistance, lack of specificity, and toxicity. To overcome these challenges, drug repurposing has emerged as a promising strategy in breast cancer treatment.

OBJECTIVE

The aim of this investigation was to assess the influence of calcitriol on breast cancer cell lines expressing ErbB2 and comparing its effects with the conventional treatment, neratinib.

METHODS

We employed an MTT test to determine cell viability and utilized staining techniques to assess cell apoptosis. Flow cytometry was used to evaluate cell cycle arrest, while a scratch wound healing test was performed to examine cancer cell migration ability. Additionally, gene expression studies were conducted for calcitriol and neratinib to support our hypothesis regarding the ErbB2 gene.

RESULTS

The repurposing of calcitriol demonstrated enhanced efficacy in suppressing cancer cell growth in ErbB2- positive breast cancer. Proportionally, calcitriol significantly reduced the viability of SK-BR-3 cells, similar to neratinib. Furthermore, calcitriol exhibited significant cytotoxicity against neratinib and substantially reduced breast cancer cell growth. These findings were corroborated by the wound healing assay, cell cycle arrest analysis, and gene expression studies, demonstrating comparable efficacy to the standard treatment, neratinib.

CONCLUSION

The findings from this investigation offer compelling proof that highlights the promising role of calcitriol as an adjuvant drug with antiproliferative and antitumoral effects in the management of ErbB2-positive breast carcinoma patients. Therefore, we recommend further evaluation of calcitriol in clinical settings, particularly for the treatment of ErbB2-positive breast cancer, as it shows promise as a valuable therapeutic option.

A comparative study of different animal hairs: A microscopic analysis

Hair is a feature that is only found in mammals. In all species, it is an epidermal protrusion composed of an outer cuticle, middle cortex, and inner medulla. Hair's primary purpose in mammals is to aid with thermoregulation. Every domestic animal species has a distinct hair pattern that can be used in forensic investigations. The aim of the present study is to observe the different animal hairs under stereomicroscope for forensic analysis. Hair is a unique characteristic seen only in mammals. It is an epidermal protrusion composed of an outer cuticle, middle cortex, and inner medulla in all species. The primary function of hair in animals is to aid with thermoregulation. Every domestic animal species has a specific hair pattern that forensic investigators can employ. The shaft profile was straight in all the animal hairs. In the proximal end, the root was absent because the hair was cut from the respective animals. Cuticles were absent in all the hair strands. The surface texture was smooth in dog hair, rough and spiculated in cat hair, and coarse in horse and rat hair. Microscopic examination of hairs reveals morphological distinctions that allow animal hairs from different species to be distinguished. In forensic investigations, microscopic examinations of various animal hairs are useful.

Comparative study of male and female human hair: A microscopic analysis

The outer cuticle, middle cortex, and inner medulla make up hair, which is an epidermal outgrowth. Hair is resilient under harsh natural conditions, thus it is frequently collected at crime scenes, making human hair analysis important in the forensic sciences field. It aids in the formation of a triangle connecting a crime scene, a victim, and a culprit. The aim of this study is to observe the microscopic structure of male and female human hair. Samples of hair specimens from males and females were collected. The materials used were ethanol to degrease and a stereomicroscope to observe the structural differences between the male and female hair samples. The comparison between male and female hair is done on the grounds of color, shaft profiles, the proximal and distal ends of the hair, cuticle, and surface texture, and the other found characters. This study of comparison between male and female hair specimens revealed that the hair color at the distal end is found to be brown for females while it is completely black in that of males, and the surface texture of males is found to have some irregularities while there are no irregularities in female. This study can be concluded that the structural comparison between male and female hair specimens can be used as evidence for forensic analysis at crime scenes.

Knowledge and awareness of the Klinefelter Syndrome among the dental students

The presence of one or more extra X chromosomes in a male causes Klinefelter Syndrome (KS). KS affects 1 in 500-1 in 1000 men, while about half remain undiagnosed. KS is characterized by huge stature, increase in arm length, the feminine distribution of adipose tissues (including gynecomastia), less or pubic hair, infertility, hypotonia, reduced size of penis and less than average verbal IQ, struggle in learning and requirements for less specified speech therapy. KS is a primary testicular insufficiency with high levels of gonadotropin caused by a lack of pituitary gland feedback. The aim of the study is to assess the knowledge and awareness of the KS among the dental students. This cross-sectional survey was conducted among dental students of a private dental hospital. To evaluate the knowledge and awareness of the participants about KS, a self-administered questionnaire consisting of 10 questions was prepared. Percentage analysis and frequency analysis and percentage analysis were performed. A Chi-square test was done to assess the correlation using the SPSS software. In our study, most of the participants were aware of the KS. They also knew that the KS is caused due to the additional X chromosome. We would like to conclude that the dental students were much aware about the Klinefelter and they also had a thorough knowledge about it.

Salivary vitamin D levels among OSCC and normal Indian patients

Oral Squamous Cell Carcinoma comprises nearly 90% of all Oral cancers. Recent studies on Oral Squamous Cell Carcinoma are done with a focus on identification of factors that affect the outcome of treatment, one of which is vitamin D levels. The aim of this study was to evaluate vitamin D3 levels in patients with Oral Squamous Cell Carcinoma and Normal Population with saliva as a biomarker. The study sample comprised of 40 subjects, of whom 20 were patients diagnosed with OSCC and 20 healthy subjects. The salivary samples obtained were assessed using Vitamin D3 ELISA kit. The mean salivary Vitamin D3 levels were 39.09 ng/dl among OSCC patients and 44.49 ng/dl among healthy subjects. Salivary Vitamin D levels in OSCC patients were found to be significantly less compared to the healthy controls. More than 90% of cancers of the oral cavity are Oral Squamous Cell Carcinoma (OSCC). Recent studies are done with a focus on identification of factors affecting the treatment of cancer, one of which is vitamin D levels. The aim of the study was to evaluate salivary vitamin D3 levels in patients with Oral Squamous Cell Carcinoma and in Normal Population. 40 patients were selected for the study. Salivary samples collected were assessed using Vitamin D3 ELISA Kit-EDI Total 25-OH Vitamin D EIA Kit to detect the salivary vitamin D levels. Mean Salivary Vitamin D3 levels were found to be 39.09 ng/dl in OSCC patients and 44.49 ng/dl in healthy subjects. A salivary Vitamin D level in OSCC patients was found to be significantly less compared to the healthy controls. Decreased Vitamin D3 levels in patients with OSCC indicate that Vitamin D3 deficiency increases the rate of cell proliferation, invasion, angiogenesis & metastasis in patients with OSCC. Vitamin D level is likely to reduce the severity of the disease and hence Vitamin D supplementation for OSCC patients in the early stages of treatment and after treatment can be done to enhance the prognosis.

Modulation of Nrf2 by activation of estrogen receptor β as a therapeutic strategy to prevent cancer development and overcome inflammation-related drug resistance in breast cancer

Despite the tremendous progress in breast cancer diagnosis and treatment, the mortality rate is expected to increase due to the emergence of drug resistance. Pro-inflammatory markers are thought to contribute to drug resistance by activation of its naive receptors and its downstream signaling pathways. Elevation of pro-inflammatory markers leads to an increase in the biosynthesis of estrogen which can promote the proliferation of estrogen receptor (ER)+ breast cancer. Inflammation also results in obesity which is one of the key risk factors. Estrogen receptor-beta (ER-β) is an important target that has been widely studied and accepted to possess anti-cancer activity in a number of cancers including breast cancer. ER-β elicits its action through genomic and non-genomic pathways. The genomic pathway increases the transcription of potent cyclin-dependent kinase inhibitor (p21), and tumor suppressor genes such as melanoma differentiation associated gene 7 and tumor protein (p53). The non-genomic pathway works through protein-protein interaction and phosphorylation. Here, we propose that the activation of ER-β might enhance the activation of nuclear factor-erythroid factor 2-related factor 2 (Nrf2) via estrogen receptor-alpha (ER-α) repression. The activation of Nrf2 increases the transcription of antioxidant genes such as NADH quinone oxidoreductase 1 (NQO1), heme oxygenase-1 (HO-1), etc., and decreases the expression of pro-inflammatory genes such as tumor necrosis factor-α (TNF-α), interleukin-1 (IL-1), etc. This review hypothesizes and suggests that ER-β agonists could play a beneficial role to overcome inflammation-related drug resistance by modulation of the Nrf2/antioxidant response element (Nrf2/ARE) pathway.

In vitro anti-inflammatory and wound healing properties of Andrographis echioides and Andrographis paniculata

Andrographis echioides (L.) is an annual herbaceous plant in the family Acanthaceae. Anti-inflammatory is the property of a substance or treatment that reduces inflammation or swelling. Antioxidants are substances that can prevent or slow damage to cells caused by free radicals, unstable molecules that the body produces as a reaction to environmental and other pressures. They are sometimes called "free-radical scavengers. Therefore, it is of interest to analyse the anti-inflammatory and antioxidant properties of Andrographis echioides and Andrographis paniculata. Protease inhibitor activity was done by bovine serum albumin was added to 100µl of plant sample with increase in concentrations (100-500µg/ml). Invitro antioxidant activity was done by DPPH free radical scavenging assay. 200 µL of 0.1 mM DPPH prepared in methanol was added to 100 µL of the plant extract with increase in concentration. Based on the results from the present study, it can be concluded that A.echioides is found to be a good natural antioxidant source and A. paniculata is found to be a good anti-inflammatory source. However, both the plant A.echioides and A.paniculata have these properties. Data shows that both A.echioides and A. paniculata have potential anti-inflammatory and antioxidant activity which could be due to the presence of bioactive compounds present in the plant extracts.

Network-based drug repurposing: A critical review

New drug development for a disease is a tedious time taking, complex and expensive process. Even if it is done, still the chances for success of newly developed drugs are very low. Modern reports state that repurposing the pre-existing drugs will have more efficient functioning than newly developed drugs. This repurposing process will save time, reduce expenses and provide more success rate. The only limitation for this repurposing is getting a desired pharmacological and characteristic parameter of various drugs from vast data available about a huge number of drugs, their effects, and target mechanisms. This drawback can be avoided by introducing computational methods of analysis. This includes various network analysis types that use various biological processes and relationships with various drugs to make data interpretation a simple process. Some of the data sets now available in standard and simplified forms include gene expression, drug-target interactions, protein networks, electronic health records, clinical trial results, and drug adverse event reports. Integrating various data sets and interpretation methods gives way for a more efficient and easy way to repurpose an exact drug for desired target and effect. In this review, we are going to discuss briefly various computational biological network analysis methods like gene regulatory networks, metabolic networks, protein-protein interaction networks, drug-target interaction networks, drug-disease association networks, drug-drug interaction networks, drug-side effects networks, integrated network-based methods, semantic link networks, and isoform-isoform networks. Along with these, we have also briefly presented limitations, predicting methods, data sets used of various biological networks used of the drug for drug repurposing.

Chandamarutha Chenduram, an Indian traditional Siddha preparation attenuated the neuronal degeneration in ischemic mice through ameliorating cytokines and oxy-radicals mediated EAAT-2 dysfunction

ETHNOPHARMACOLOGICAL RELEVANCE

Chandamarutha Chenduram (CC), an Indian traditional Siddha preparation officially recorded in the Siddha formulary of India and its composition are widely used in the Siddha practice of neurological disorders like stroke/paralysis in India. However, the scientific validation and mechanistic evidence is lacking and yet to be elucidated.

AIM OF THE STUDY

To establish the scientific evidences and to explore the possible neuroprotective mechanism of CC in cerebral ischemia.

MATERIALS AND METHODS

Chemical standardization of the CC was performed using atomic absorption spectroscopy and gravimetric analysis. Acute toxicity study for CC in mice was performed in accordance with OECD 423 guidelines. CC (5 mg/kg) and CC (10 mg/kg) were investigated in bilateral common carotid occlusion (BCCAo) model in mice. After, behavioral assessments, the brain samples were collected and the hippocampus region was micro-dissected for neurotransmitter, neurobiochemicals and inflammatory cytokines estimation. The excitatory amino acid transporter-2 (EAAT-2) expressions was analyzed by RT-PCR to understand the possible molecular mechanism. In addition, hematoxylin and eosin staining of CA1 hippocampal brain region was performed to support the neuroprotective effect of CC in ischemic condition.

RESULTS

Chemical standardization analysis showed that CC has acceptable range of mercury (0.82 ppm) and elemental sulphur (11% w/w). Also, other heavy metal limits were found to be less or not detectable. Toxicity study also evidenced the safety profile of CC. CC has significantly reversed the behavioral dysfunctions (p < 0.001) in global ischemic mice. Treatment with CC has attenuated the excitatory neurotransmitter glutamate, lipid peroxide, nitric oxide, cytokines (IL-1β, TNF-α) (p < 0.001) and increased the antioxidant enzymes (SOD, CAT, GSH) and EAAT-2 expression level (p < 0.001) in ischemic brain. The hematoxylin and eosin staining in CA1 region of hippocampus also evidence the neuroprotective effect exhibited by CC.

CONCLUSIONS

Treatment with CC has exhibited dose dependent effect and CC10 has shown significant protective effect in comparison to CC5 in most of the parameters studied. CC prevented further degeneration of neurons in cerebral ischemic mice through ameliorating inflammatory cytokines and oxy-radicals mediated EAAT-2 dysfunction and subsequent excitotoxicity in neurons.
