Simvastatin prevents BMP-2 driven cell migration and invasion by suppressing oncogenic DNMT1 expression in breast cancer cells
This study emphasized to decipher the molecular mechanism of endogenous regulation of DNMT1 expression for finding upstream signaling molecules. Cancer database analyses found an upregulated DNMT1 expression in most cancer types including breast cancer. Overexpression of DNMT1 showed an increased cell migration, invasion, and stemness potential whereas 5-azacytidine (DNMT1 inhibitor) and siRNA mediated knockdown of DNMT1 exhibited inhibition of such cancer activities in breast cancer MDA-MB-231 and MCF-7 cells. Infact, cancer database analyses further found a positive correlation of DNMT1 transcript with both cholesterol p...

Renoprotective Effect of KLF2 on Glomerular Endothelial Dysfunction in Hypertensive Nephropathy
Cells. 2022 Feb 22;11(5):762. doi: 10.3390/cells11050762.ABSTRACTKruppel-like factor 2 (KLF2) regulates endothelial cell metabolism; endothelial dysfunction is associated with hypertension and is a predictor of atherosclerosis development and cardiovascular events. Here, we investigated the role of KLF2 in hypertensive nephropathy by regulating KLF2 expression in human primary glomerular endothelial cells (hPGECs) and evaluating this expression in the kidney tissues of a 5/6 nephrectomy mouse model as well as patients with hypertension. Hypertension-mimicking devices and KLF2 siRNA were used to downregulate KLF2 expression...

Excessive expression of miR-1a by statin causes skeletal injury through targeting mitogen-activated protein kinase kinase kinase 1
CONCLUSION: Statin causes skeletal injury through induction of miR-1a excessive expression to decrease MAP3K1 gene expression.PMID:33864447 | DOI:10.18632/aging.202839

Endothelial Klf2-Foxp1-TGF β signal mediates the inhibitory effects of simvastatin on maladaptive cardiac remodeling
Conclusions: We conclude that cardiac microvasculature ECs are important in the modulation of pressure overload induced maladaptive cardiac remodeling and dysfunction, and the endothelial Klf2-TGFβ1 or Klf2-Foxp1-TGFβ1 pathway mediates the preventive effects of simvastatin. This study demonstrates a novel mechanism of the non-cholesterol lowering effects of simvastatin for HF prevention.

Simvastatin Suppresses Human Breast Cancer Cell Invasion by Decreasing the Expression of Pituitary Tumor-Transforming Gene 1
Statins, or 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors, have been widely used to lower cholesterol and prevent cardiovascular diseases. Recent preclinical and clinical studies have shown that statins exert beneficial effects in the management of breast cancer, while the underlying mechanisms remain to be elucidated. Herein, we sought to investigate the effect of statins on the expression of pituitary tumor-transforming gene 1 (PTTG1), a critical gene involved in human breast cancer invasion and metastasis. Our results showed that PTTG1 is highly expressed in malignant Hs578T and MDA-MB-231 breast cancer cel...

Simvastatin Protects Dopaminergic Neurons Against MPP < sup > + < /sup > -Induced Oxidative Stress and Regulates the Endogenous Anti-Oxidant System Through ERK
Conclusion: Our results provide strong evidence that ERK1/2-mediated modulation of the anti-oxidant system after simvastatin treatment may partially explain the anti-oxidant activity in experimental parkinsonian models. These findings contribute to a better understanding of the critical roles of simvastatin via the ERK1/2-mediated modulation of the anti-oxidant system, which may be relevant for treating PD.Cell Physiol Biochem 2018;51:1957 –1968

OPN b and c Isoforms Doubtless Veto Anti-angiogenesis Effects of Curcumin in Combination with Conventional AML Regiment
Authors: Mirzaei A, Ghaffari SH, Nikbakht M, Kamranzadeh Foumani H, Vaezi M, Mohammadi S, Alimoghaddam K, Ghavamzadeh A Abstract Osteopontin (OPN) is an extracellular structural protein that is secreted by osteoblasts and hematopoietic cells. It suppresses the proliferation of hematopoietic stem and also plays an important role in promoting survival and drug resistance in leukemic stem cells (LSCs). Since the role of OPN isoforms in AML angiogenesis are remaining controversial, in the present study, we aimed to evaluate whether curcumin (CUR), as a known natural component with anti-angiogenesis effects, in a combin...

Geranylgeraniol prevents the simvastatin-induced PCSK9 expression: Role of the small G protein Rac1
Publication date: August 2017 Source:Pharmacological Research, Volume 122 Author(s): Nicola Ferri, Silvia Marchianò, Maria Giovanna Lupo, Annalisa Trenti, Giuseppe Biondo, Paola Castaldello, Alberto Corsini Statins are known to increase the plasma levels of proprotein convertase subtilisin kexin type 9 (PCSK9) through the activation of the sterol responsive element binding protein (SREBP) pathway due to the inhibition of cholesterol biosynthesis. In the present study, we explore a possible role of the prenylated proteins on the statin-mediated PCSK9 induction in Caco-2 cells. Simvastatin (40μM) induced both PCSK9 mRNA (...

Simvastatin Up ‐Regulates Annexin A10 That Can Inhibit the Proliferation, Migration, and Invasion in Androgen‐Independent Human Prostate Cancer Cells
CONCLUSIONOur results suggest that statins inhibit the proliferation, migration, and invasion of androgen‐independent prostate cancer cells by up‐regulation of ANXA10. Additionally, it is possible that S100A4 plays a role in these effects. Statins may be beneficial in the prevention and/or treatment of prostate cancer. Prostate © 2016 Wiley Periodicals, Inc.

Interferon regulatory factor 4 (IRF4) controls myeloid-derived suppressor cell (MDSC) differentiation and function.
In this study, we found that IRF4 expression was remarkably suppressed during the development of MDSCs in the tumor microenvironment. Both the mRNA and protein levels of IRF4 in MDSCs were gradually reduced, depending on the development of tumors in the 4T1 model. siRNA-mediated knockdown of IRF4 in bone marrow cells promoted the differentiation of PMN-MDSCs. Similarly, IRF4 inhibition in bone marrow cells using simvastatin, which has been known to inhibit IRF4 expression, increased PMN-MDSC numbers. In contrast, IRF4 overexpression in bone marrow cells inhibited the total numbers of MDSCs, especially PMN-MDSCs. Notably, t...
