This study was designed to decipher potential mechanisms underscoring oxLDL-evoked regulation of ET-1 and signaling pathways involved in endothelial cells. ET-1 mRNA expression, secretion and promoter function were determined using RT-PCR, enzyme immunometric and luciferase assays, respectively. GO and GSEA bioinformatics analyses depicted differentially expressed genes (DEGs) mainly associated with cell proliferation, cell division, cellular structure, energy supply, and apoptosis in oxLDL-challenged endothelial cells. Incubation of oxLDL overtly increased ROS production, apoptosis, mRNA level, secretion and promoter activity of ET-1 in human umbilical vein endothelial cells (HUVECs), the effects were mitigated by N-Acetyl Cysteine (NAC). Moreover, oxLDL challenge evoked phosphorylation of extracellular signal-regulated kinase1/2 (ERK1/2) in HUVECs, the effect was reversed by NAC and MEK inhibitor PD98059. NAC and PD98059 nullified oxLDL- induced rises in mRNA expression, secretion and promoter activity of ET-1. Truncation of 5’-flanking sequence of ET-1 (–566 bpLuc to –250 bpLuc) displayed elevated luciferase activity with 24-h oxLDL incubation. Fusion plasmid from –233 and –185 bp Luc drastically dampened luciferase activity in basal and oxLDL-challenged HUVECs. Transfection of reporter construct –250 bp Luc with a 2 bp mutation at AP-1 locus, removed basal and oxLDL- evoked rises in ET-1 promoter activity. Collectively, our findings support that oxLDL evoked activation of ERK1/2 signaling likely through ROS production, en route to upregulation of endothelial transcriptional factor AP-1, resulting in expression and secretion of ET-1.","PeriodicalId":94047,"journal":{"name":"International journal of drug discovery and pharmacology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81139244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To protect the body from damage during exercise or confrontations, beneath the human epidermal layer, the human body has evolved a coverall gown: the extracellular matrix (ECM). ECM provides a suitable space for the survival and activity of cells in the body, and affects the behavior of cells through signal transduction system. Proteoglycans, particularly the small leucine rich proteoglycan (SLRP) family, have been shown to be molecules that play important roles in matrix remodeling and organ fibrosis, such as by affecting ECM components or altering the intracellular environment. But in recent years reports of SLRP families, their manifestations in different organs have not been consistent. Recent studies suggest that proteoglycans entering the blood in a soluble form hold promise as diagnostic biomarkers of organ fibrosis and may provide novel therapeutic strategies for fibrotic diseases. Herein, we discuss and review studies of SLRPs in multi-organ fibrotic diseases.","PeriodicalId":94047,"journal":{"name":"International journal of drug discovery and pharmacology","volume":"73 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88511823","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The myocardial blood supply must be restored as soon as possible to reduce the mortality risk, however, reperfusion itself paradoxically leads to further death of cardiomyocytes and increases the infarct size; this is known as myocardial ischemia/reperfusion injury (MIRI). The pathological mechanism of MIRI is complex, and current research mainly focuses on oxidative stress, dysfunctional mitochondrial energy metabolism, Ca 2+ overload, endoplasmic reticulum stress (ERs) and the inflammatory response. This review briefly summarizes the mechanism of MIRI, and natural plant product (NPP) components proven to ameliorate MIRI and their related signaling pathways. NPPs can alleviate MIRI by regulating oxidative stress, inflammation, ERs, Ca 2+ overload and mitochondrial function maintenance. This review will deepen our understanding of how NPPs reduce MIRI and the future value of NPPs in cardio-protection.","PeriodicalId":94047,"journal":{"name":"International journal of drug discovery and pharmacology","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87771300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients with AMI complicated by MDD often have poor prognosis. Most early studies focused on how AMI leads to MDD, but there are few reports on depression-induced AMI. In terms of mechanism, inflammation, the hypothalamic-pituitary-adrenal axis (HPA axis) and brain-gut axis may be involved in the occurrence and development of MDD after AMI. The inflammatory injury, abnormal sympathetic and vagal nerve activity, HPA axis overactivation, overeating and some therapeutic medicine administration in patients with MDD can also be risk factors for AMI. Both behavioral and pharmaceutical interventions are important for the treatment of AMI with MDD. More drugs are being developed and tested. At present, there are still many issues, needing to be addressed, in the diagnosis, pathogenesis, intervention strategies and therapeutic drugs for AMI with MDD. To aid clinical diagnosis and treatment, this review classifies the existing studies on AMI complicated with MDD, and also includes some of our considerations.","PeriodicalId":94047,"journal":{"name":"International journal of drug discovery and pharmacology","volume":"89 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85964398","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Epilepsy-induced psychiatric co-morbidity and mortality impose a huge burden on patients, their families, and society. Anti-seizure medications (ASMs) are drugs used to control seizures in patients with epilepsy. Epilepsy constitutes a spectrum of disorders, with various underlying causes. Hence, finding the right drug to control seizures with minimal side effects is a difficult task for clinicians. Besides controlling seizures, many ASMs have off-target effects that result in unwanted side effects. Compared to first and second-generation drugs, third-generation drugs have shown better tolerance. Even though the target of many ASMs is known, their mechanism of action is not well understood. The main mechanism behind epilepsy is defined as an imbalance in the excitatory-to-inhibitory ratio in neurotransmission. So, the key target of ASMs is the ion channels controlling the intrinsic property of neurons like sodium channels, potassium channels, and calcium channels, the excitatory synaptic transmission via glutamate receptors, and the inhibitory synaptic transmission by GABA receptors. Here we review the role of ion channels in epilepsy, and how the ASMs act on them for seizure control.","PeriodicalId":94047,"journal":{"name":"International journal of drug discovery and pharmacology","volume":"86 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73923511","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The function of miR-21 depends upon its expression level in the specific cell types and downstream targets, which determine cell fate. Under pathological conditions, the expression level of miR-21 is altered, leading to abnormal gene regulation of downstream signaling and cardiovascular diseases such as hypertension, cardiac hypertrophy and fibrosis, atherosclerosis, and heart failure. Agomirs or antagomirs can be introduced into the respective tissue type to reverse or stop the progression of the disease. Exosomes in the extracellular vesicles, which mediate many cellular events with high biocompatibility, have a high potential of efficiently delivering miR-21 to their targeted cells. The critical role of miR-21 in cardiovascular disease (CVD) is indisputable, but there are controversial reports on the function of miR-21 in the same disease.

Different approaches have been developed to investigate underlying mechanisms. Transvenous approach (TA) is widely used for studies but has several drawbacks. We therefore developed a novel minimally invasive approach (MIA) for mechanistic studies. Study included 27 male C57BL/6J mice, 19 for MIA and 8 for TA. Under general anaesthesia, ECG was recorded. A key hole was made on the right first intercostal space by separating the intercostal muscles, followed by the exposure of the superior vena cava and the top of the atrium. An EPR-800 catheter was inserted vertically, perpendicular to the chest, for atrial pacing and flatly over the ventricles for ventricular pacing. Burst S1–S1 and decremental S1–S2 pacing protocols were performed to evaluate SA recovery time (SNRT), the atrioventricular node effective refractory period (AVN-ERP), Wenckebach period, ventricular ERP, and arrhythmia susceptibility. MIA was successfully performed in all 19 mice without any complications. One mouse died during TA due to venous rupture. Compared MIA with TA, surgical time were significantly shorter (P<0.0001). Wenckebach period was shorter as well (P<0.05). No difference was found in baseline sinus cycle length, SNRT, correct SNRT, AVN-ERP, ventricular ERP, and arrhythmia susceptibility (all P>0.05). The novel MIA outplays TA by providing similar outcomes of PES but consuming less time, demanding less surgical expertise, and reducing the potential of surgical complications. Given the minimal tissue injury, it also provides great potential as a recovery procedure for longitudinal study.","PeriodicalId":94047,"journal":{"name":"International journal of drug discovery and pharmacology","volume":"133 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-03-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87208815","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the plethora of new research is their unique interaction with drugs is even more striking. Exosomes play essential roles in disease treatment either as extracellular vesicles to exert biological functions or as drug carriers to deliver therapeutic agents. We summarized the relationship between exosomes and drugs in the disease progression and treatment. Understanding how exosomes interact with drugs and exert their anti-inflammatory and pro-angiogenic effects, alongside a lipid peroxidation inhibitory result in different manners is essential for disease treatment.","PeriodicalId":94047,"journal":{"name":"International journal of drug discovery and pharmacology","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78032966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
