Types of glioma brain tumors and genetic alterations in signaling pathways in them Background & Objective: Glioma is a common type of primary brain tumor originating in the glial cells that surrounds and supports neurons in the brain. These tumors arise from three different types of cells that are normally found in the brain: astrocytes, oligodendrocytes, and ependymal cells, accordingly types ...
Mammalian mechanistic target of rapamycine (mTOR) is a conserved serine/threonine kinase in the cellular PI3K/Akt/mTOR signaling pathway. This pathway is modified by cellular alterations such as level of energy, growth factors, stresses, as well as the increased environmental level of cancerous cytokines. In general, increase of this kinase protein function is seen in various types of cancers, ...
Background & Aims : Cancer cells proliferation may be mediated by abnormal phosphorylation of signaling pathways downstream of tyrosine kinase receptors such as Platelet derived growth factor receptor α (PDGFR-α) and β (PDGFR-β). We aimed to study the phosphorylation level of PDGFR-α and PDGFR-β and apoptosis in mouse normal leydig cells being exposed to Imatinib. Materials & Methods : The ...
Background: Cutaneous leishmaniasis is one of the most important parasitic diseases in humans. In this disease, one of the responsible organisms is Leishmania major, which is transmitted by sandfly vector. There are specific differences in biochemical profiles and metabolite pathways in logarithmic and stationary phases of Leishmania parasites. In the present study, 1H NMR spectroscopy was used...
Objective(s):Intermittent hypoxia (IH), caused by obstructive sleep apnea (OSA), could cause hippocampus or neuron damage through multiple signaling pathways, while the underlying mechanisms are still unclear. Thus, the present study aimed to explore the effect of IH on the biological functions of microglia cells. Materials and Methods:Cell proliferation of BV2 cells after exposure to IH were o...
Background and aim: Aberrant activation of diverse intracellular signaling pathways involved in differentiation, cell growth, apoptosis. These pathways include known oncogenic pathways such as Janus kinase-signal transducer and activator of transcription (JAK/STAT) pathway. The JAK/STAT signaling pathway plays an important role in many cellular functions. This pathway can be activated by variou...
