MicroRNAs play key roles in tumor proliferation and invasion. Here we show distinct expression of miR-222-3p between ERα-positive and ERα-negative endometrial carcinoma (EC) cell lines and primary tumors, and investigation of its relationship with ERα and other clinical parameters. In vitro, the function of miR-222-3p was examined in RL95-2 and AN3CA cell lines. MiR-222-3p expression was negati...
Despite recent therapeutic advances that have doubled the median survival time of patients with multiple myeloma, intratumor genetic heterogeneity contributes to disease progression and emergence of drug resistance. miRNAs are noncoding small RNAs that play important roles in the regulation of gene expression and have been implicated in cancer progression and drug resistance. We investigated th...
The main objective of this research is measurement and assessment of the Radon-222 and Radium-226 radioactive levels in mineral water and drinking water in the Sareyn city. The guidelines used for Radon-222 and Radium-226 radiation sampling and analysis were ASTM D: 5072-09 and ISO 13165-1: 2013, respectively. The concentration of Radon-222 and radium-226 in mineral water and drinking water sam...
MicroRNAs (miRNAs) comprise a novel class of endogenous, small, noncoding RNAs that negatively regulate gene expression. Functionally, an individual miRNA is as important as a transcription factor because it is able to regulate the expression of its multiple target genes. Recently, miR-221 and miR-222 have been found to play a critical role in cancer cell proliferation. However, their roles in ...
The amino acid-derived polyamines are organic cations that are essential for growth in all mammalian cells, but their exact roles at the molecular level remain largely unknown. Here we provide evidence that polyamines promote the translation of cyclin-dependent kinase 4 (CDK4) by the action of CUG-binding protein 1 (CUGBP1) and microRNA-222 (miR-222) in intestinal epithelial cells. Both CUGBP1 ...
MicroRNAs (miRNAs) play important roles in cancer formation and progression by suppressing the production of key functional proteins at the post-transcriptional level in a sequence-specific manner. While differential expression of miRNAs is widely observed in cancers including prostate cancer (PCa), how these miRNAs are transcriptionally regulated is largely unknown. MiRNA-221 and miRNA-222 (mi...
The anesthetic MS-222 (i.e., tricaine, Finquel) is widely used by biologists on amphibians in the field, even though field use of MS-222 on amphibians is not approved by the U.S. Food and Drug Administration (FDA). Previous studies have identified the impact of MS-222 on vision, olfaction, stress, heart, and liver, and have documented its lethality to certain microbes that commonly populate amp...
Tricaine (MS-222) is used commonly for sedation, immobilization, and anesthesia of poikilothermic animals. The anesthetic efficacy of different concentrations of MS-222 was compared to benzocaine and pentobarbital on the physiological changes, heart rate and ECG (electrocardiogram) parameters in the leopard frog, Rana pipiens. Loss of righting reflex (RR), loss of pain response (NR = nociceptor...
miR-221/-222 and components of the urokinase-type plasminogen activator system (uPAS) are associated with metastasis and poor prognosis in breast cancer, including the triple-negative subtype (TNBC). Modification of components of uPAS and involved miRNAs may contribute to targeted therapy for breast cancer patients. miR-221-/-222-overexpressing or miR-221-depleted cells were employed for qRT-PC...
SMITH, D. G. S’mpathetic cardiac stimulation in Bufo marinus under MS-222 anesthesia. Am. J. Physiol. 226(Z) : 367-370. 1974.-The cardiac stimulant effect of tricaine methanesulfonate (MS-222 Sandoz) was studied in unrestrained intact toads (Bufo marinus). During anesthesia in a 1 : 1000 solution of MS-222, the average heart rate rose from 26 to 46 beats/min, and the average systemic arterial p...
