Estrogens play very important role in opening the transcription event, which is a final step of activation of the first order mediators as receptors or channels in the cell wall by information coming from the outside of the cell. For the long time the exact step by step mechanism of cellular transfer of information to the cell nuclei was not known. Currently many new informations are available. Very important seems the step of phosp Read More

The present article attempts to provide, on the basis of data emerging from studies carried out in our laboratories, a summary of the chemical and pharmacological properties of the new compound N-[(4-trifluoromethyl)benzyl]4- methoxybutyramide (GET73). Particular emphasis is given to findings obtained in vivo and in vitro suggesting that an allosteric modulation of metabotropic glutamate receptor 5 (mGlu5 receptor) by Read More

Studies with breast cancer cells, showed that microRNAs (miRNAs) act as regulators of signaling pathways playing a key role in tumor progression and being targeted in chemotherapy. Deregulation of these pathways by altered miRNA expression or single nucleotide polymorphisms (SNPs) found in certain miRNA genes have been shown to lead tumor growth, metastasis, angiogenesis, and drug resistance. miRNAs have also Read More

Complex molecular and cellular mechanisms are involved in the pathway of liver fibrosis. Activation and transformation of hepatic stellate cells (HSCs) are considered the two main reasons for the cause and development of liver fibrosis. The peroxisome proliferator-activated receptors (PPARs) belonging to the family of ligand-activated transcription factors play a key role in liver homeostasis, regulating adipogenesis and Read More

This review examines the biological role of oxidants and antioxidants continuously produced by all living cells. Physiologically, human beings, who have inherited good genes, used to eat moderately a healthy diet and exercised daily, both systems are equally important and essential in maintaining a normal long life. However, the aging process slowly leads to a disequilibrium that is accentuated in pathologies such as dia Read More

Leptin is an adipokine with pleiotropic actions that regulates food intake, energy metabolism, inflammation and immunity, and also participates in the complex mechanism that regulates skeleton biology, both at bone and cartilage level. Leptin is increased in obesity and contributes to the “low-grade inflammatory state” of obese subjects causing a cluster of metabolic aberrations that affects joints and bone. In this review, we re Read More
