Apoptosis, a naturally programmed cellular death mechanism, kills abnormal cells produced by mitosis. Cancer can develop when this equilibrium is disrupted, either by an upsurge in cell propagation or a reduction in tissue demise. Cancer therapy aims to cause cancer cells to die while inflicting little harm to healthy cells. This review of apoptotic mechanism processes improves our understanding of how certain malignancies begin and develop. The current cancer treatments can operate either by inducing apoptosis or causing direct cell damage. An insight into the resistance to apoptosis may explicate why malignancy treatments fail in some situations. New therapies grounded on our understanding of apoptotic processes are being developed to induce apoptosis of cancer cells while limiting the simultaneous death of normal cells. Various biological activities require redox equilibrium to function properly. : Antineoplastic medications that cause oxidative stress by raising ROS and blocking antioxidant mechanisms have recently attracted much interest. The rapid accumulation of ROS impairs redox balance and damages cancer cells severely. Here, we discuss ROS-instigating malignancy therapy and the antineoplastic mechanism used by prooxidative drugs.","PeriodicalId":10865,"journal":{"name":"Current molecular pharmacology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139506448","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through transcriptional and post-transcriptional regulation, the downstream target genes of HIF can trigger multiple pathological responses in the body, including energy metabolism, cytopenia, and angiogenesis. There are three distinct subtypes of HIF: HIF-1, HIF-2, and HIF-3. HIF-1 is a significant regulator of the cellular response to hypoxia, and the balance between its production and degradation is critical for this response. As hypoxia is linked to several disorders, understanding HIF can open up novel avenues for the treatment of many diseases. This review describes the regulatory mechanisms of HIF-1 synthesis and degradation and the clinical significance of the hypoxia-inducible factor pathway in lung injury, kidney disease, hematologic disorders, and inflammation-related diseases.","PeriodicalId":10865,"journal":{"name":"Current molecular pharmacology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139477148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods:: Real-time PCR and western blotting were used to determine c-Fos expression levels in KSHV-infected (SK-RG) and uninfected SH-SY5Y cells. C-Fos levels were measured again in SK-RG cells with or without Notch1 knockdown. Next, we measured c-Fos and p-c-Fos concentrations after treatment with the Notch1 γ-secretase inhibitor LY-411575 and the Notch1 activator Jagged-1. MTT and Ki-67 staining were used to evaluate the proliferation ability of cells after c-Fos levels downregulation. CyclinD1, CDK6, and CDK4 expression levels and cell cycle were analyzed by western blotting and flow cytometry, respectively. After the c-Fos intervention, the KSHV copy number and gene expression of RTA, LANA and K8.1 were analyzed by real-time TaqMan PCR. Results:: C-Fos was up-regulated in KSHV-infected SK-RG cells. However, the siRNA-mediated knockdown of Notch1 resulted in a significant decrease in the levels of c-Fos and p-c-Fos (P <0.01, P <0.001). Additionally, a decrease in Cyclin D1, CDK6, and CDK4 was also detected. The Notch1 inhibitor LY-411575 showed the potential to down-regulate the levels of c-Fos and p-c-Fos, which was consistent with Notch1 knockdown group (P <0.01), whereas the expression and phosphorylation of c-Fos were remarkably up-regulated by treatment of Notch1 activator Jagged-1 (P <0.05). In addition, our data obtained by MTT and Ki-67 staining revealed that the c-Fos down-regulation led to a significant reduction in cell viability and proliferation of the SK-RG cells (P <0.001). Moreover, FACS analysis showed that the cell cycle was arrested in the G0/G1 stage, and the expressions of Cyclin D1, CDK6, and CDK4 were down-regulated in the c-Fos-knockdown SK-RG cells (P <0.05). Reduction in total KSHV copy number and expressions of viral genes (RTA, LANA and K8.1) were also detected in c-Fos down-regulated SK-RG cells (P <0.05). Conclusion:: Our findings strongly indicate that c-Fos plays a crucial role in the promotion of cell proliferation through Notch1 signaling in KSHV-infected cells. Furthermore, our results suggest that the inhibition of expression of key viral pathogenic proteins is likely involved in this process.","PeriodicalId":10865,"journal":{"name":"Current molecular pharmacology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139476543","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The sustained activation of pancreatic stellate cells (PSCs) plays a pivotal role in the progression of pancreatic fibrosis and is a major source of extracellular matrix (ECM) deposition during pancreatic injury. Methods:: Calpain is a calcium-independent lysosomal neutral cysteine endopeptidase and was found to be correlated to various fibrotic diseases. Studies have revealed that calpeptin, a calpain inhibitor, can improve the fibrosis process of multiple organs. This study investigated the effect of the calpain inhibitor, calpeptin, on fibrosis in experimental CP and activation of cultured PSCs in mice. CP was induced in mice by repeated injections of cerulein for four weeks in vivo, and the activation process of mouse PSCs was isolated and cultured in vitro. Then, the inhibitory effect of calpeptin on pancreatic fibrosis was confirmed based on the histological damage of CP, the expression of α-smooth muscle actin (α-SMA) and collagen-Iα1(Col1α1), and the decrease in mRNA levels of calpain-1 and calpain-2. Results:: In addition, it was revealed that calpeptin can inhibit the activation process of PSCs and induce significant PSCs apoptosis by downregulating the expression of calpain-1, calpain-2 and TGF-β1, and the expression and phosphorylation of smad3 in vitro. Conclusion:: These results suggest that the calpain inhibitor, calpeptin, plays a key role in the regulation of PSC activation by inhibiting the TGF-β1/smad3 signaling pathway, which supports the potential of calpeptin as an inhibitor of pancreatic fibrosis in mice by interfering with calpain.","PeriodicalId":10865,"journal":{"name":"Current molecular pharmacology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139477154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cold shock proteins (CSPs), including CIRP and RBM3 are highly expressed in the skin; however, it is unknown whether CSPs are involved in the wound-healing impairment of diabetic skin. Objective: The objective of this study is to investigate the effects of RBM3 on skin wound healing in diabetes. Methods: In vitro experiments, western blot assay was used to test the levels of proteins in HaCaT cells treated with different concentrations of glucose. RBM3 was over-expressed in HaCaT cells using lentivirus particles. Cell viability was analyzed by Cell-Counting Kit-8 assay and colony formation assay. The migration of HaCaT cells at different concentrations of glucose was evaluated by wound healing assay. In vivo experiments, the mouse model of diabetes was established by intraperitoneal injection of streptozotocin. Four weeks later, the mice were anesthetized by intraperitoneal injection of pentobarbital sodium for skin tissue collection or wound healing experiments. RBM3 knockout mice were established by removing exons 2–6 using the clustered regularly interspaced short palindromic repeats (CRISPR)-Cas9 technique and then used in skin wound healing experiments with or without diabetic stress. Results: In this study, the expression of RBM3, rather than CIRP, was altered in the skin of diabetic specimens, and the RBM3’s overexpression accelerated the cell viability and proliferation of HaCaT cells under high glucose conditions. RBM3 deficiency caused delayed wound healing in RBM3 knockout in diabetic conditions. Moreover. RBM3 enhanced the ERK1/2 signaling pathway, and its inhibitor FR180204 blocked the beneficial effect of RBM3 overexpression on skin wound healing in diabetes. Conclusion: RBM3 activated the ERK1/2 signal to facilitate skin wound healing in diabetes, offering a novel therapeutic target for its treatment.","PeriodicalId":10865,"journal":{"name":"Current molecular pharmacology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135111812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its effect on cardiac hypertrophy and the underlying mechanisms remain unclear. Objective: This study aimed to investigate the effect of ART on cardiac hypertrophy and explore its possible mechanisms. Materials and Methods: A rat model was established by intraperitoneal injection of isoproterenol (ISO) for 3 days, and the degree of myocardial hypertrophy was compared among 5 groups: a control (CON) group, an ISO group, and groups treated with different doses of ART (7 mg/kg/d, 35 mg/kg/d, and 75 mg/kg/d). Echocardiography was used to evaluate cardiac function and structure. The cross-sectional area of cardiomyocytes was measured by hematoxylin and eosin (H&E) staining. The heart weight (HW), body weight (BW), and tail length were measured, and the HW/tail length ratio and the HW/BW ratio were calculated. H9C2 rat cardiomyocytes were cultured, and different amounts of ART were added 2 hours before ISO stimulation. Phalloidin staining was used to evaluate the degree of cell hypertrophy. The levels of atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP) were quantified in rat plasma and cell supernatant using enzyme-linked immunosorbent assay (ELISA), while the expression levels of p- ERK1/2, p-JNK, and p-p38 MAPK were assessed in the myocardium and H9C2 cells via western blot analysis. Conclusion: The mechanism of ART against cardiac hypertrophy was related to inhibition of the ERK1/2 and p38 MAPK signaling pathways. Result: Intragastric administration of ART at a dosage of 35 mg/kg/d or over-mitigated the early-stage cardiac hypertrophy induced by ISO in rats led to a reduction in left ventricular posterior wall diastolic thickness, interventricular septal thickness at diastole, lowered ANP and BNP levels, as well as a decrease in HW/tail length and HW/BW ratio. In vitro studies demonstrated that ART at a concentration of 100 μM inhibited ISO-mediated hypertrophy of H9C2 cells. The ISO group showed a higher p-ERK/GAPDH ratio and p-p38 MAPK/GAPDH ratio than the control group both in vivo and in vitro. Although the p-JNK/GAPDH ratio was increased in the ISO group, there was no statistical difference. The p-ERK/GAPDH and p-p38/GAPDH ratios were significantly lower in the ART group than in the ISO group.","PeriodicalId":10865,"journal":{"name":"Current molecular pharmacology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135922774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After co-treatment (of AS-IV and Vit-D at respective doses of 50 mg/kg via oral gavage and 30000 IU/kg via intramuscular injection), blood glucose levels, markers of inflammation and oxidative stress, as well as apoptosis and histopathology were evaluated with appropriate techniques. Results: Co-treatment could effectively reduce blood glucose levels substantially (p< 0.01), improve weight loss, and decrease oral glucose tolerance. Reduced respective sensory and motor nerve conduction velocities in rats were substantially improved (p<0.01) after co-treatment. Also, we observed obvious improvement in DH-induced injured nerve fiber myelin structure and other organ pathologies in co-treated rats. Besides, we observed up-regulated expressions of peroxisomal-proliferator activated receptor-alpha (PPAR-α) and Vit-D receptors (VDR) (p< 0.01) through the western blotting technique. Using the same technique, we also discovered reduced levels of interleukin (IL)1 beta, IL-6, and tumor necrosis factor-alpha, coupled with increased IL-10 and superoxide dismutase levels (p< 0.01). Importantly, co-treatment could effectively exert antioxidative and anti-inflammatory effects. Also, co-treatment resulted in the up-regulation of PPAR-α and VDR expressions, inhibition of the renin–angiotensin–aldosterone system, and promotion of β-cell sensitivity to insulin.
