Abstract
ABSTRACT Pulmonary arterial hypertension (PAH) is characterized by pulmonary arterial endothelial cell (PAEC) dysfunction and pulmonary arterial smooth muscle cell (PASMC) activation. For decades, the therapies for PAH based on stem cells have been shown to be effective. Meanwhile, tumor necrosis factor-α-induced protein-8-like 2 (TIPE2) promote the viability of human amniotic mesenchymal stem cells. Therefore, we aimed to explore the role of TIPE2 in adipose-derived stem cells (ADSCs) and the function of TIPE2-transfected ADSCs in the regulation of PAH. We first explored the role and underlying molecular mechanism of TIPE2 in viability and migration of ADSCs. Moreover, the ADSCs transfected with TIPE2 were cocultured with monocrotaline pyrrole (MCTP)-stimulated PASMCs or PAECs. The effects and mechanisms of TIPE2-transfected ADSCs on MCTP-induced PASMCs and PAECs were further investigated. The results showed that TIPE2 overexpression promoted viability and migration of ADSCs by activating the TLR4-ERK1/2 pathway. In addition, TIPE2-transfected ADSCs inhibited the abnormal proliferation and the impaired apoptosis of PASMCs via NF-κB signaling and promoted the conversion of PASMCs from synthetic to contractile. Meanwhile, TIPE2-transfected ADSCs reduced the apoptosis, endothelial-to-mesenchymal transition, and migration of PAECs via PI3K/AKT signaling after MCTP treatment. MCTP-induced oxidative stress and inflammation of PAECs were significantly decreased by TIPE2-transfected ADSCs. In rat model, TIPE2-ADSCs administration further decreased the monocrotaline-induced increase in the right ventricular systolic pressure and ratio of right ventricle weight/left ventricle and septa weight (L + S) and right ventricle weight/body weight compared with the ADSCs group. In conclusion, TIPE2-transfected ADSCs dramatically attenuated the PAH via inhibiting the dysfunction of PASMCs and PAECs.

Abstract
Pulmonary hypertension (PH) is a progressive, pulmonary vascular disease with high morbidity and mortality. Unfortunately, the pathogenesis of PH is complex and remains unclear. Existing studies have suggested that inflammatory factors are key factors in PH. Interleukin-6 (IL-6) is a multifunctional cytokine that plays a crucial role in the regulation of the immune system. Current studies reveal that IL-6 is elevated in the serum of patients with PH and it is negatively correlated with lung function in those patients. Since IL-6 is one of the most important mediators in the pathogenesis of inflammation in PH, signaling mechanisms targeting IL-6 may become therapeutic targets for this disease. In this review, we detailed the potential role of IL-6 in accelerating PH process and the specific mechanisms and signaling pathways. We also summarized the current drugs targeting these inflammatory pathways to treat PH. We hope that this study will provide a more theoretical basis for targeted treatment in patients with PH in the future.

Mol Biol Rep 2023; 50:5439-5454. [PMID: 37155017 DOI: 10.1007/s11033-023-08363-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2022] [Accepted: 09/01/2022] [Indexed: 05/10/2023]
Abstract
BACKGROUND Nigella sativa and its main bioactive ingredient, thymoquinone, exhibit various pharmacological activities, including neuroprotective, nephroprotective, cardioprotective, gastroprotective, hepatoprotective, and anti-cancer effects. Many studies have been conducted trying to elucidate the molecular signaling pathways that mediate these diverse pharmacological properties of N. sativa and thymoquinone. Accordingly, the goal of this review is to show the effects of N. sativa and thymoquinone on different cell signaling pathways. METHODS The online databases Scopus, PubMed and Web of Science were searched to identify relevant articles using a list of related keywords such as Nigella sativa, black cumin, thymoquinone, black seed, signal transduction, cell signaling, antioxidant, Nrf2, NF-κB, PI3K/AKT, apoptosis, JAK/STAT, AMPK, MAPK, etc. Only articles published in the English language until May 2022 were included in the present review article. RESULTS Studies indicate that N. sativa and thymoquinone improve antioxidant enzyme activities, effectively scavenges free radicals, and thus protect cells from oxidative stress. They can also regulate responses to oxidative stress and inflammation via Nrf2 and NF-κB pathways. N. sativa and thymoquinone can inhibit cancer cell proliferation through disruption of the PI3K/AKT pathway by upregulating phosphatase and tensin homolog. Thymoquinone can modulate reactive oxygen species levels in tumor cells, arrest the cell cycle in the G2/M phase as well as affect molecular targets including p53, STAT3 and trigger the mitochondrial apoptosis pathway. Thymoquinone, by adjusting AMPK, can regulate cellular metabolism and energy hemostasis. Finally, N. sativa and thymoquinone can elevate brain GABA content, and thus it may ameliorate epilepsy. CONCLUSIONS Taken together, the improvement of antioxidant status and prevention of inflammatory process by modulating the Nrf2 and NF-κB signaling and inhibition of cancer cell proliferation through disruption of the PI3K/AKT pathway appear to be the main mechanisms involved in different pharmacological properties of N. sativa and thymoquinone.

Abstract
Cancer is a pervasive, constantly evolving, and significant public health concern. The number of new cancer cases has risen dramatically in the last decades, making it one of the top causes of poor health and mortality worldwide. Although various treatment strategies, including surgery, radiation, and pharmaceutical therapies, have evolved into more sophisticated, precise methods, there is not much improvement in the cancer-related death toll. Consequently, natural product-based therapeutic discoveries have recently been considered an alternative approach. According to an estimate, one-third of the top twenty medications in today's market have a natural plant-product-based origin. Accordingly, primary prevention is an essential component of worldwide cancer control. This review provides an overview of the mechanisms of action of bioactive ingredients in natural dietary products that may contribute to the prevention and management of multiple malignancies.

Abstract
Introduction Current targeted pulmonary arterial hypertension (PAH) therapies have improved lung hemodynamics, cardiac function, and quality of life; however, none of these have reversed the ongoing remodeling of blood vessels. Considering notopterol, a linear furocoumarin extracted from the root of traditional Chinese medicine Qiang-Huo (Notopterygium incisum), had shown the antiproliferative and anti-inflammatory properties in previous studies, we hypothesized that it could play a role in ameliorating PAH. Methods In vivo, we conducted monocrotaline (MCT) induced PAH rats and treated them with notopterol for 3 weeks. Then, the rats were examined by echocardiography and RV catheterization. The heart and lung specimens were harvested for the detection of gross examination, histological examination and expression of inflammatory molecules. In vitro, human pulmonary arterial smooth muscle cells (HPASMCs) were treated with notopterol after hypoxia; then, cell proliferation was assessed by cell counting kit-8 and Edu assay, and cell migration was detected by wound healing assays. Results We found that notopterol improved mortality rate and RV function while reducing right ventricular systolic pressure in MCT-induced PAH rats. Furthermore, notopterol reduced right ventricular hypertrophy and fibrosis, and it also eased pulmonary vascular remodeling and MCT-induced muscularization. In addition, notopterol attenuated the pro-inflammatory factor (IL-1β, IL-6) and PCNA in the lungs of PAH rats. For the cultured HPASMCs subjected to hypoxia, we found that notopterol can inhibit the proliferation and migration of HPASMCs. Conclusion Our studies show that notopterol exerts anti-inflammatory and anti-proliferative effects in the pulmonary arteries, which may contribute to prevention of PAH.

Abstract
Pulmonary arterial hypertension (PAH) is a progressive and rare disease without obvious clinical symptoms that shares characteristics with pulmonary vascular remodeling. Right heart failure in the terminal phase of PAH seriously threatens the lives of patients. This review attempts to comprehensively outline the current state of knowledge on PAH its pathology, pathogenesis, natural medicines therapy, mechanisms and clinical studies to provide potential treatment strategies. Although PAH and pulmonary hypertension have similar pathological features, PAH exhibits significantly elevated pulmonary vascular resistance caused by vascular stenosis and occlusion. Currently, the pathogenesis of PAH is thought to involve multiple factors, primarily including genetic/epigenetic factors, vascular cellular dysregulation, metabolic dysfunction, even inflammation and immunization. Yet many issues regarding PAH need to be clarified, such as the "oestrogen paradox". About 25 kinds monomers derived from natural medicine have been verified to protect against to PAH via modulating BMPR2/Smad, HIF-1α, PI3K/Akt/mTOR and eNOS/NO/cGMP signalling pathways. Yet limited and single PAH animal models may not corroborate the efficacy of natural medicines, and those natural compounds how to regulate crucial genes, proteins and even microRNA and lncRNA still need to put great attention. Additionally, pharmacokinetic studies and safety evaluation of natural medicines for the treatment of PAH should be undertaken in future studies. Meanwhile, methods for validating the efficacy of natural drugs in multiple PAH animal models and precise clinical design are also urgently needed to promote advances in PAH.

Abstract
The world is witnessing a difficult time. The race of developing a new coronavirus (COVID-19) vaccine is becoming more urgent. Many preliminary studies on the pathophysiology of COVID-19 patients have provided some clues to treat this pandemic. However, no suitable treatment has found yet. Various symptoms of patients infected with COVID-19 indicated the importance of immune regulation in the human body. Severe cases admitted to the intensive care unit showed high level of pro-inflammatory cytokines which enhanced the disease severity. Acute Respiratory Distress Syndrome (ARDS) in COVID-19 patients is another critical factor of disease severity and mortality. So, Immune modulation is the only way of regulating immune system. Nigella sativa has been used for medicinal purposes for centuries. The components of this plant are known for its intense immune-regulatory, anti-inflammatory, and antioxidant benefits in obstructive respiratory disorders. A molecular docking study also gave evidences that N. sativa decelerates COVID-19 and might give the same or better results than the FDA approved drugs. The aim of this review was to investigate the possible immune-regulatory effects of N. sativa on COVID-19 pandemic. Our review found N. sativa's Thymoquinone, Nigellidine, and α-hederin can be a potential influencer in reinforcing the immune response on molecular grounds.

Abstract
Pulmonary artery hypertension (PAH) is a disease with high morbidity and mortality. Cyanidin‑3‑O‑β‑glucoside (Cy‑3‑g), a classical anthocyanin, has a variety of biological effects. The present study evaluated whether Cy‑3‑g attenuated PAH, and explored the potential mechanism of action. Rats were injected with monocrotaline (MCT; 60 mg per kg of body weight) and then treated with Cy‑3‑g (200 or 400 mg per kg of body weight) for 4 weeks. Protein expression was determined in vitro in transforming growth factor‑β1 (TGF‑β1)‑mediated human pulmonary arterial smooth muscle cells (SMCs). The results indicated that Cy‑3‑g significantly inhibited the mean pulmonary artery pressure, right ventricular systolic pressure and right ventricular hypertrophy index, as well as vascular remodeling induced by MCT in PAH rats. Further experiments showed that Cy‑3‑g suppressed the expression of pro‑-inflammatory factors and enhanced the levels of anti‑inflammatory factors. Cy‑3‑g blocked oxidative stress and improved vascular endothelial injury. Cy‑3‑g also reduced the proliferation of SMCs. Furthermore, the MCT‑ and TGF‑β1‑induced increase in TGF‑β1, phosphorylated (p)‑p38 mitogen‑activated protein kinase (MAPK) and p‑cAMP‑response element binding protein (CREB) expression was blocked by Cy‑3‑g treatment in vivo and in vitro. These results indicated that Cy‑3‑g could prevent vascular remodeling in PAH via inhibition of the TGF‑β1/p38 MAPK/CREB axis.

Abstract
In recent times, scientific attention has been paid to different foods and their bioactive components for the ability to inhibit the onset and progress of different types of cancer. Nigella sativa extract, powder and seed oil and its main components, thymoquinone and α-hederin, have showed potent anticancer and chemosensitizing effects against various types of cancer, such as liver, colon, breast, renal, cervical, lung, ovarian, pancreatic, prostate and skin tumors, through the modulation of various molecular signaling pathways. Herein, the purpose of this review was to highlight the anticancer activity of Nigella sativa and it constitutes, focusing on different in vitro, in vivo and clinical studies and projects, in order to underline their antiproliferative, proapoptotic, cytotoxic and antimetastatic effects. Particular attention has been also given to the synergistic effect of Nigella sativa and it constitutes with chemotherapeutic drugs, and to the synthesized analogs of thymoquinone that seem to enhance the chemo-sensitizing potential. This review could be a useful step towards new research on N. sativa and cancer, to include this plant in the dietary treatments in support to conventional therapies, for the best achievement of therapeutic goals.

Front Pharmacol 2021; 12:618493. [PMID: 33790787 PMCID: PMC8005533 DOI: 10.3389/fphar.2021.618493] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/17/2020] [Accepted: 01/19/2021] [Indexed: 02/01/2023] Open
Abstract
Vascular remodeling (VR), induced by the massive proliferation and reduced apoptosis of vascular smooth muscle cells (VSMCs), is primarily responsible for many cardiovascular conditions, such as restenosis and pulmonary arterial hypertension. Sodium selenite (SSE) is an inorganic selenium, which can block proliferation and stimulate apoptosis of tumor cells; still, its protective effects on VR remains unknown. In this study, we established rat models with carotid artery balloon injury and monocrotaline induced pulmonary arterial hypertension and administered them SSE (0.25, 0.5, or 1 mg/kg/day) orally by feeding tube for 14 consecutive days. We found that SSE treatment greatly ameliorated the development of VR as evidenced by an improvement of its characteristic features, including elevation of the ratio of carotid artery intimal area to medial area, right ventricular hypertrophy, pulmonary arterial wall hypertrophy and right ventricular systolic pressure. Furthermore, PCNA and TUNEL staining of the arteries showed that SSE suppressed proliferation and enhanced apoptosis of VSMCs in both models. Compared with the untreated VR rats, lower expression of PCNA and CyclinD1, but higher levels of Cleaved Caspase-3 and Bax/Bcl-2 were observed in the SSE-treated rats. Moreover, the increased protein expression of MMP2, MMP9, p-AKT, p-ERK, p-GSK3β and β-catenin that occurred in the VR rats were significantly inhibited by SSE. Collectively, treatment with SSE remarkably attenuates the pathogenesis of VR, and this protection may be associated with the inhibition of AKT and ERK signaling and prevention of VSMC’s dysfunction. Our study suggest that SSE is a potential agent for treatment of VR-related diseases.

Abstract
Since the beginning of the SARS-CoV-2(severe acute respiratory syndrome-coronavirus-2) pandemic, arace to develop a vaccine has been initiated, considering the massive and rather significant economic and healthcare hits that this virus has caused. The pathophysiology occurring following COVID-19(coronavirus disease-2019) infection has givenhints regarding the supportive and symptomatic treatments to establish for patients, as no specific anti-SARS-CoV-2 is available yet. Patient symptoms vary greatly and range from mild symptoms to severe fatal complications. Supportive treatments include antipyretics, antiviral therapies, different combinations of broad-spectrum antibiotics, hydroxychloroquine and plasma transfusion. Unfortunately, cancer patients are at higher risk of viral infection and more likely to develop serious complications due to their immunocompromised state, the fact that they are already administering multiple medications, as well as combined comorbidity compared to the general population. It may seem impossible to find a drug that possesses both potent antiviral and anticancer effects specifically against COVID-19 infection and its complications and the existing malignancy, respectively. Thymoquinone (TQ) is the most pharmacologically active ingredient in Nigella sativa seeds (black seeds); it is reported to have anticancer, anti-inflammatory and antioxidant effects in various settings. In this review, we will discuss the multiple effects of TQ specifically against COVID-19, its beneficial effects against COVID-19 pathophysiology and multiple-organ complications, its use as an adjuvant for supportive COVID-19 therapy and cancer therapy, and finally, its anticancer effects.

Interferon regulatory factor 7 inhibits rat vascular smooth muscle cell proliferation and inflammation in monocrotaline-induced pulmonary hypertension. Life Sci 2021; 264:118709.

Abstract
AIMS Although interferon regulatory factor 7 (IRF7) has known roles in regulating the inflammatory response, vascular smooth muscle cell proliferation, and apoptosis, its role in the pathogenesis of pulmonary hypertension (PH) is unclear. We hypothesized that IRF7 overexpression could inhibit pulmonary vascular remodeling and slow the progression of PH. MAIN METHODS IRF7 mRNA and protein levels in the lung samples and pulmonary artery smooth muscle cells (PASMCs) isolated from monocrotaline (MCT)-induced PH rats were assessed. We evaluated the effects of IRF7 on inflammation, proliferation, and apoptosis using an in vivo MCT-induced PH rat model and in vitro methods. KEY FINDINGS We noted decreased IRF7 mRNA and protein levels in the pulmonary vasculature of MCT-induced PH rats. IRF7 upregulation attenuated pulmonary vascular remodeling, decreased the pulmonary artery systolic pressure, and improved the right ventricular (RV) structure and function. Our findings suggest that nuclear factor kappa-Bp65 (NF-κBp65) deactivation could confer pulmonary vasculature protection, reduce proinflammatory cytokine (tumor necrosis factor-α, interleukin 6) release, and decrease PASMC proliferation and resistance to apoptosis via deactivating transcription factor 3 (ATF3) signaling. ATF3 deactivation induced the downregulation of the proliferation-dependent genes proliferating cell nuclear antigen (PCNA), cyclin D1, and survivin, coupled with increased levels of B cell lymphoma-2-associated X protein (Bax)/B cell lymphoma-2 (Bcl2) ratio, and cleaved caspase-3 in PASMCs. SIGNIFICANCE Our findings showed that IRF7 downregulation could initiate inflammation via NF-κBp65 signaling, causing PASMC proliferation via ATF3 signaling pathway activation. Therefore, IRF7 could be a potential molecular target for PH therapy.

Abstract
Thymoquinone is one of the main components present in Nigella sativa seeds and is known to have various biological functions in inflammation, oxidative stress, tumors, aging, and in lowering blood glucose levels. Few studies have focused on its neuroprotective effects and its regulation of small-molecule metabolites during cerebral ischemia reperfusion injury. In this study, transient middle cerebral occlusion (tMCAO) was used to establish the rat model of cerebral ischemia reperfusion injury. We investigated the effects of thymoquinone using matrix-assisted laser desorption ionization mass spectrometry imaging (MALDI-MSI) in a model of ischemia reperfusion injury to explore the changes in small-molecule metabolites in the brain. We found that that thymoquinone significantly improved neurobehavioral scores, reduced the cerebral infarct area, alleviated brain edema, and increased the number of normal neurons following injury. MALDI-MSI revealed that thymoquinone reduced abnormal accumulations of glucose, citric acid, succinate and potassium ions. Thymoquinone also increased the amount of energy-related molecules such as ADP, AMP, GMP, and creatine, antioxidants such as glutathione, ascorbic acid, and taurine, and other metabolism-related molecules such as glutamate, glutamine, aspartate, N-acetyl-L-aspartate, and sodium ions in damaged areas of the brain following cerebral ischemia reperfusion injury. In summary, based on the neuroprotective effect of thymoquinone on cerebral ischemia reperfusion injury, this study revealed the regulation of thymoquinone on energy metabolism and small-molecule substance metabolism.

Abstract
Pulmonary arterial hypertension (PAH) is a fatal syndrome resulting from enhanced pulmonary arterial pressure and pulmonary vessel resistance. Perivascular inflammation and extracellular matrix deposition are considered to be the crucial pathophysiologic bases of PAH. Formononetin (FMN), a natural phytoestrogen isolated from red clover (Trifolium pratense), has a variety of proapoptotic, anti-inflammatory and anti-tumor activities. However, the therapeutic effectiveness of FMN for PAH remains unclear. In the present study, 60 mg/kg monocrotaline (MCT) was first used to induce PAH in rats, and then all rats were treated with different concentrations of FMN (10, 30 and 60 mg/kg/day). At the end of this study, the hemodynamics and pulmonary vascular morphology of rats were evaluated. Specifically, matrix metalloproteinase (MMP)2, transforming growth factor β1 (TGFβ1) and MMP9 were measured using western blot and immunohistochemical staining. Collagen type I, collagen type III, fibronectin, monocyte chemotactic protein-1, tumor necrosis factor-α, interleukin-1β, ERK and NF-κB were quantified using western blotting. The results demonstrated that FMN significantly alleviated the changes of hemodynamics and pulmonary vascular morphology, and decreased the MCT-induced upregulations of TGFβ1, MMP2 and MMP9 expression levels. Meanwhile, the expression levels of collagen type I, collagen type III and fibronectin in rat lungs decreased after FMN treatment. Furthermore, the phosphorylated ERK and NF-κB also decreased after FMN treatment. Taken together, the present study indicated that FMN serves a therapeutic role in the MCT-induced PAH in rats via suppressing pulmonary vascular remodeling, which may be partially related to ERK and NF-κB signals.

Abstract
Pulmonary arterial hypertension (PAH) is a life‑threatening disease induced by the excessive proliferation and reduced apoptosis of pulmonary artery smooth muscle cells (PASMCs). Formononetin (FMN) is a natural isoflavone with numerous cardioprotective properties, which can inhibit the proliferation and induce the apoptosis of tumor cells; however, whether FMN has a therapeutic effect on PAH remains unclear. In the present study, PAH was induced in rats with monocrotaline (MCT, 60 mg/kg); rats were then administered FMN (10, 30 or 60 mg/kg/day). At the end of the experiment, hemodynamic changes, right ventricular hypertrophy and lung morphological characteristics were evaluated. α‑smooth muscle actin (α‑SMA), proliferating cell nuclear antigen (PCNA), and TUNEL were detected by immunohistochemical staining. The expression of PCNA, Bcl‑2‑associated X protein (Bax), Bcl‑2 and, cleaved caspase‑3, and activation of AKT and ERK were examined by western blot analysis. The results demonstrated that FMN significantly ameliorated the right ventricular systolic pressure, right ventricular hypertrophy, and pulmonary vascular remodeling induced by MCT. FMN also attenuated MCT‑induced increased expression of α‑SMA and PCNA. The ratio of Bax/Bcl‑2 and cleaved caspase‑3 expression increased in rat lung tissue in response to FMN treatment. Furthermore, reduced phosphorylation of AKT and ERK was also observed in FMN‑treated rats. Therefore, FMN may provide protection against MCT‑induced PAH by preventing pulmonary vascular remodeling, potentially by suppressing the PI3K/AKT and ERK pathways in rats.

Abstract
The excessive proliferation and migration of vascular smooth muscle cells (VSMCs) are mainly responsible for vascular occlusion diseases, such as pulmonary arterial hypertension and restenosis. Our previous study demonstrated thymoquinone (TQ) attenuated monocrotaline‐induced pulmonary arterial hypertension. The aim of the present study is to systematically examine inhibitory effects of TQ on platelet‐derived growth factor‐BB (PDGF‐BB)–induced proliferation and migration of VSMCs in vitro and neointimal formation in vivo and elucidate the potential mechanisms. Vascular smooth muscle cells were isolated from the aorta in rats. Cell viability and proliferation were measured in VSMCs using the MTT assay. Cell migration was detected by wound healing assay and Transwell assay. Alpha‐smooth muscle actin (α‐SMA) and Ki‐67‐positive cells were examined by immunofluorescence staining. Reactive oxygen species (ROS) generation and apoptosis were measured by flow cytometry and terminal deoxyribonucleotide transferase–mediated dUTP nick end labelling (TUNEL) staining, respectively. Molecules including the mitochondria‐dependent apoptosis factors, matrix metalloproteinase 2 (MMP2), matrix metalloproteinase 9 (MMP9), PTEN/AKT and mitogen‐activated protein kinases (MAPKs) were determined by Western blot. Neointimal formation was induced by ligation in male Sprague Dawley rats and evaluated by HE staining. Thymoquinone inhibited PDGF‐BB–induced VSMC proliferation and the increase in α‐SMA and Ki‐67‐positive cells. Thymoquinone also induced apoptosis via mitochondria‐dependent apoptosis pathway and p38MAPK. Thymoquinone blocked VSMC migration by inhibiting MMP2. Finally, TQ reversed neointimal formation induced by ligation in rats. Thus, TQ is a potential candidate for the prevention and treatment of occlusive vascular diseases.

Abstract
Pulmonary arterial hypertension (PAH) is reported to contribute to right ventricular failure and death. PAH of variable degrees is often related to congenital heart disease (CHD). Galectin-3 (Gal-3) has been proven to be of great importance in PAH and CHD. Therefore, we investigated the specific mechanism of Gal-3 in CHD-PAH. Patients with CHD-PAH were enrolled to detect the changes of T-cell subsets, cytokine levels, and other related inflammatory cells in the plasma and to assess the Gal-3 levels in the serum. Next, CHD-PAH mouse models were established and treated with restored or depleted Gal-3 to evaluate the systolic pulmonary artery pressure (sPAP) and right ventricular hypertrophy index (RVHI), to determine levels of IL-4, IL-5, IL-13, AKT and p-AKT along with proliferation of pulmonary artery smooth muscle cells (PASMCs). Finally, we explored the effects of adoptive transfer of CD4+T cells on CHD-PAH in mice with Gal-3 knockdown to further investigate the role of Gal-3 in vivo. Initially, Gal-3 was up-regulated in patients with CHD-PAH. Subsequently, it was demonstrated that restored Gal-3 increased sPAP and RVHI, and promoted proliferation of PASMCs by activating the immune response with elevated levels of IL-4, IL-5, IL-13 and p-AKT. Finally, adoptive transfer of CD4+T cells promoted CD4+T cell perivascular infiltration and the progression of CHD-PAH in mice with Gal-3 knockdown. Collectively, the current study suggests a facilitating role of Gal-3 in pulmonary artery remodeling and progression of CHD-PAH via activation of Th2.

Abstract
Our study investigated the ameliorative effects of thymoquinone (TQ) on the pulmonary blood vessels which were injured after intratracheal administration of Escherichia coli-derived lipopolysaccharide (LPS) in a rat model. Forty rats (150 ± 50 g) were randomly divided into four groups equally. The first group was intratracheally administered LPS (Escherichia coli O55:B5) at a dose 200 μg. The second group was co-administered intraperitoneal injection of TQ and LPS daily for one week. The third group was provided intraperitoneal injection of 1 mg of TQ. The fourth group was administered normal saline intratracheally at the rate of 200 μl. The results revealed that cytokine level of interleukin-1 beta (IL-1β) and tumor necrosis factor alpha (TNFα) in serum was reduced in TQ-treated rats. Immunohistochemical study showed that expression of NF-kB was countered in the lung tissue by the application of TQ. In addition, the lesion score for various pathological aberrations were checked when rats were treated with TQ. From the results of the present study, it was concluded that TQ has an ameliorative effect on the pulmonary blood vascular damage via rearrangement of the cytokines in response to LPS injury in the rat model.

Abstract
The higher consumption of fruit, herbs, spices, and vegetables is well known and practical strategy to cure human cancers owing to their presence of bioactive compounds. Among these, Nigella sativa is a promising source of bioactive compounds including thymoquinone, monoterpenes, p-cymene and α-piene etc. Thymoquinone has been found effective to inhibit the different cancer stages such as proliferation, migration and invasion. It also acts as anticancer agent against different human cancers such as breast, pancreatic, prostate, blood, oral, bone, head and neck, cervical, liver and lung. It significantly mediated miR-34a up-regulation, enhanced the levels of miR-34a through p53, and down controlled Rac1 expression. Thymoquinone induces apoptosis, regulates the levels of pro- and anti- apoptotic genes. It also has been known to lower the phosphorylation of NF-κB and IKKα/β and reduces the metastasis as well as also lowered the ERK1/2 and PI3K activities. Thymoquinone inhibits the metastasis through activation of JNK and p38. The present review article highlights the anticancer perspectives of thymoquinone in human by various pathways and use of this compound as diet based therapy has proven new pharmacological agent against several types of cancers.

3,7-Bis(2-hydroxyethyl)icaritin, a potent inhibitor of phosphodiesterase-5, prevents monocrotaline-induced pulmonary arterial hypertension via NO/cGMP activation in rats. Eur J Pharmacol 2018; 829:102-111.

Abstract
Pulmonary arterial hypertension (PAH) is a chronic progressive disease which leads to elevated pulmonary arterial pressure and right heart failure. 3,7-Bis(2-hydroxyethyl)icaritin (ICT), an icariin derivatives, was reported to have potent inhibitory activity on phosphodiesterase type 5 (PDE5) which plays a crucial role in the pathogenesis of PAH. The present study was designed to investigate the effects of ICT on monocrotaline (MCT)-induced PAH rat model and reveal the underlying mechanism. MCT-induced PAH rat models were established with intragastric administration of ICT (10, 20, 40 mg/kg/d), Icariin (ICA) (40 mg/kg/d) and Sildenafil (25 mg/kg/d). The mean pulmonary arterial pressure (mPAP) and right ventricle hypertrophy index (RVHI) were measured. Pulmonary artery remodeling was assessed by H&E staining. Blood and lung tissue were collected to evaluate the level of endothelin 1 (ET-1), nitric oxide (NO), and cyclic guanosine monophosphate (cGMP). The expressions endothelial nitric oxide synthase (eNOS) and PDE5A in lung tissues were determined by Western blot analysis. The results showed that ICT reduced RVHI and mPAP, and reversed lung vascular remodeling in rats with MCT-induced PAH. ICT also reversed MCT-induced ET-1 elevation, NO and cGMP reduction in serum or lung tissue. Moreover, ICT administration significantly induced eNOS activation and PDE5A inhibition. ICT with lower dose had better effects than ICA. In summary, ICT is more effective in preventing MCT-induced PAH in rats via NO/cGMP activation compared with ICA. These findings demonstrate a novel mechanism of the action of ICT that may have value in prevention of PAH.

Dihydromyricetin prevents monocrotaline-induced pulmonary arterial hypertension in rats. Biomed Pharmacother 2017; 96:825-833.

Abstract
Pulmonary artery hypertension (PAH) is a chronic and deadly disease, for which effective medical treatments are lacking. Here, we investigated whether 2R,3R-dihydromyricetin (DHM) could prevent monocrotaline (MCT)-induced PAH in rats. The MCT-injected rats were treated with normal saline or DHM (100mg/kg body weight/d) for 4 weeks, followed by measurements of right ventricular systolic pressure (RVSP), right ventricular hypertrophy index (RVHI), pulmonary arterial remodeling (PAR), and expression levels of IL-6, TNF-α, and IL-10. In vitro, we assessed the role of DHM on IL-6-induced migration of primary human pulmonary arterial smooth muscle cells (HPASMCs). We found that DHM treatment attenuated changes in RVSP, RVHI, and PAR in MCT-injected PAH rats. The observed increase of IL-6 levels in PAH rats was inhibited by DHM treatment. In vitro, DHM pretreatment reduced IL-6-induced HPASMC migration. Furthermore, MCT- and IL-6-mediated increases in MMP9 and P-STAT3 (tyr705) PY-STAT3 levels were suppressed by DHM treatment in vivo and in vitro. These results suggest that DHM could prevent MCT-induced rat PAH and IL-6-induced HPASMC migration through a mechanism involving inhibiting of the STAT3/MMP9 axis.

Abstract
The cardioprotective benefits of aldehyde dehydrogenase 2 (ALDH2) are well established, although the regulatory role of ALDH2 in vascular remodeling in pulmonary arterial hypertension (PAH) is largely unknown. ALDH2 potently regulates the metabolism of aldehydes such as 4-hydroxynonenal (4-HNE), the endogenous product of lipid peroxidation. Thus, we hypothesized that ALDH2 ameliorates the proliferation and migration of human pulmonary artery smooth muscle cells (HPASMCs) by inhibiting 4-HNE accumulation and regulating downstream signaling pathways, thereby ameliorating pulmonary vascular remodeling. We found that low concentrations of 4-HNE (0.1 and 1μM) stimulated cell proliferation by enhancing cyclin D1 and c-Myc expression in primary HPASMCs. Low 4-HNE concentrations also enhanced cell migration by activating the nuclear factor kappa B (NF-κB) signaling pathway, thereby regulating matrix metalloprotein (MMP)-9 and MMP2 expression in vitro. In vivo, Alda-1, an ALDH2 agonist, significantly stimulated ALDH2 activity, reducing elevated 4-HNE and malondialdehyde levels and right ventricular systolic pressure in a monocrotaline-induced PAH animal model to the level of control animals. Our findings indicate that 4-HNE plays an important role in the abnormal proliferation and migration of HPASMCs, and that ALDH2 activation can attenuate 4-HNE-induced PASMC proliferation and migration, possibly by regulating NF-κB activation, in turn ameliorating vascular remodeling in PAH. This mechanism might reflect a new molecular target for treating PAH.
