Proteasome inhibitors stabilize numerous proteins by inhibiting their degradation. Previously we have demonstrated that proteasome inhibitors thiostrepton, MG132 and bortezomib paradoxically inhibit transcriptional activity and mRNA/protein expression of FOXM1. Here we demonstrate that, in addition to FOXM1, the same proteasome inhibitors also decrease mRNA and protein expression of NPM and ARF genes. These data suggest that proteasome inhibitors may suppress gene expression by stabilizing their transcriptional inhibitors.

The proteasome influences cellular homeostasis through the degradation of regulatory proteins, many of which are also involved in disease pathogenesis. In particular, numerous regulatory proteins asso...
Proteasome emerged as an important target in recent pharmacological research due to its pivotal role in degrading proteins in the cytoplasm and nucleus of eukaryotic cells, regulating a wide variety o...
It has been suggested that proteasome system has a role in initiation, progression, and complication stages of atherosclerosis. Although there is still controversy, there has been no research that com...
Fangchinoline is a bisbenzylisoquinoline alkaloid isolated from Radix Stephaniae tetrandrae S. Moore. Fangchinoline and its structure analogue, tetrandrine, exhibited direct binding affinity with reco...
The Proteasome is a ubiquitous and highly plastic multi-subunit protease with multi-catalytic activity that is conserved in all eukaryotes. The most widely known function of the Proteasome is protein ...
This study will evaluate the usefulness of plasma proteasome levels as a tumor marker of hepatocellular carcinoma (HCC) by studying their variation following curative treatment of HCC. The...
The purpose of this study is to test the safety of an investigational new drug called PR-171 at different dose levels on hematological cancers such as Multiple Myeloma, Non-hodgkin's Lymph...
The purpose of this trial is to investigate the expression of different inflammatory proteins in cancer and normal pancreatic tissue.
Trial objectives: To decide whether the addition of nelfinavir to the approved antimyeloma therapy with bortezomib and dexamethasone has sufficient activity in proteasome inhibitor-resist...
Velcade (bortezomib, PS-341) has recently been approved by the Food and Drug Administration (FDA) for the treatment of multiple myeloma (MM) for patients who have received at least one pri...
The act of ligating UBIQUITINS to PROTEINS to form ubiquitin-protein ligase complexes to label proteins for transport to the PROTEASOME ENDOPEPTIDASE COMPLEX where proteolysis occurs.
Compounds that suppress or block the plasma membrane transport of GAMMA-AMINOBUTYRIC ACID by GABA PLASMA MEMBRANE TRANSPORT PROTEINS.
A large multisubunit complex that plays an important role in the degradation of most of the cytosolic and nuclear proteins in eukaryotic cells. It contains a 700-kDa catalytic sub-complex and two 700-kDa regulatory sub-complexes. The complex digests ubiquitinated proteins and protein activated via ornithine decarboxylase antizyme.
Proteins encoded by homeobox genes (GENES, HOMEOBOX) that exhibit structural similarity to certain prokaryotic and eukaryotic DNA-binding proteins. Homeodomain proteins are involved in the control of gene expression during morphogenesis and development (GENE EXPRESSION REGULATION, DEVELOPMENTAL).
Proteins whose abnormal expression (gain or loss) are associated with the development, growth, or progression of NEOPLASMS. Some neoplasm proteins are tumor antigens (ANTIGENS, NEOPLASM), i.e. they induce an immune reaction to their tumor. Many neoplasm proteins have been characterized and are used as tumor markers (TUMOR MARKERS, BIOLOGICAL) when they are detectable in cells and body fluids as monitors for the presence or growth of tumors. Abnormal expression of ONCOGENE PROTEINS is involved in neoplastic transformation, whereas the loss of expression of TUMOR SUPPRESSOR PROTEINS is involved with the loss of growth control and progression of the neoplasm.
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
Bioinformatics is the application of computer software and hardware to the management of biological data to create useful information. Computers are used to gather, store, analyze and integrate biological and genetic information which can then be applied...
