Siah proteins: novel drug targets in the Ras and hypoxia pathways.
نویسندگان
چکیده
The Siah (seven in absentia homolog) family of RING-domain proteins are components of ubiquitin ligase complexes, targeting proteins for proteasomal degradation. Siah family members have been reported to function in Ras, estrogen, DNA-damage, and hypoxia response pathways. Although earlier reports implicated Siah proteins as tumor suppressors, recent studies in mouse models have shown that Siah inhibition impairs tumor growth and metastasis. Given their central role in oncogenic and angiogenic pathways, Siah proteins are attractive novel therapeutic targets in cancer.

Bakground: Aspergillus fumigatus is an airborne opportunistic fungal pathogen that can cause fatal infections in immunocompromised patients. Although the current anti-fungal therapies are relatively efficient, some issues such as drug toxicity, drug interactions, and the emergence of drug-resistant fungi have promoted the intense research toward finding the novel drug targets. Methods: In searc...
متن کاملLigase Seven in Absentia Homologue Tumorigenesis by Targeting the Downstream E3 Ubiquitin Inhibition of RAS-Mediated Transformation and Updated Version
Constitutively active RAS small GTPases promote the genesis of human cancers. An important goal in cancer biology is to identify means of countervailing activated RAS signaling to reverse malignant transformation. Oncogenic K-RAS mutations are found in virtually all pancreatic adenocarcinomas, making the RAS pathway an ideal target for therapeutic intervention. How to best contravene hyperactiv...

متن کاملQuercetin protects PC-12 cells against hypoxia injury by down-regulation of miR-122
Objective(s): Impairment of nerve cells of brain induced by hypoxia results in energy-deprivation and dysfunction, which accompanies with neurons apoptosis. Improving function of nerve cells is important for treating cerebral anoxia. This study aimed to investigate the role of Quercetin (Quer) in hypoxia-induced injury of pheochromocytoma (PC-12) cells. Materials and Methods: PC-12 cells were c...
