The Eph receptors are the largest sub-family of Receptor Tyrosine Kinases (RTK). They, together with their ephrin ligands, play central roles in cell-cell communication during development, and also in the maintenance of a normal adult physiology. Their malfunction, therefore, can contribute to various human diseases. Since the structures of the Eph receptors and ephrins are by now well characterized, there has been extensive Read More

Eph receptor tyrosine kinases and ephrin ligands constitute an important cell communication system that controls development, tissue homeostasis and many pathological processes. Various Eph receptors/ephrins are present in essentially all cell types and their expression is often dysregulated by injury and disease. Thus, the 14 Eph receptors are attracting increasing attention as a major class of potential drug targets. In particu Read More

Eph-ephrin system is emerging as a new potential target in several diseases including cancer, diabetes, neurodegenerative diseases and inflammation. In the last decade, several efforts have been made to develop small molecule antagonists of Eph receptors. Both natural and synthetic compounds were discovered with (poly) phenol and steroidal derivatives on one side and the α1 agonist doxazosin, 2,5-dimeth Read More

Lung cancer remains a leading cause of death. Current treatment options are generally ineffective, highlighting the dire need for novel approaches. While numerous biologically-active chemotherapeutics have been discovered in the last two decades, biological barriers including minimal water solubility, stability, and cellular resistance hinder in vivo effectiveness. To overcome these limitations, nanoparticles have been designed Read More

After the discovery of the db gene in 1966, it was determined that a blood-borne satiety factor was produced excessively, but was not responded to, in db/db mice. This model for type 2 diabetes is widely used since it phenocopies human disease and its co-morbidities including obesity, progressive deterioration in glucose tolerance, hypertension and hyperlipidaemia. Db/db mice, unlike their non-diabetic controls, have c Read More

Post-traumatic stress disorder (PTSD) is a chronic psychiatric disorder that may develop after exposure to a life-threatening trauma. As veterans and armed forces may deal with diverse health problems compared with civilians, they have a greater risk for psychiatric disorders, including PTSD, than civilians, even if the disorder may be also frequent in the general population. PTSD is associated with significant comorbidity, espec Read More

Significant progress in the research of mammalian target of rapamycin (mTOR) in recent years, has greatly enhanced our understanding of the role and cellular pathways through which mTOR control cellular processes, such as translational initiation, actin organization, cell proliferation, and cell survival. mTOR is activated by phosphorylation and functions mainly through mTOR complex 1 or mTOR complex 2. mTORC1 is activ Read More

Plasmepsins, falcipains and aminopeptidases are Plasmodium falciparum proteases involved in human host hemoglobin degradation and other processes like erythrocyte invasion and rupture. Antimalarial drug resistance and natural selection in parasite are important reasons that create the urgent need of novel targets and lead compounds to overcome the burden of malaria. This report explored progress of the study co Read More

Despite adequate surgery, women affected by advanced-stage gynaecological cancers (ovarian/ endometrial malignancies) carry an extremely poor prognosis; an improved oncological prognosis could largely depend upon the enhancement of adjuvant treatment. Recent data showed that, among women affected by endometrial/ovarian malignancies, a reduced cancer-related mortality was noted in statin-users compared t Read More
