, 2012; Denny et al., 2013) Although numerous stress conditions lead to an imbalance of proteostasis, aging is the most deleterious risk factor for the onset of protein aggregation diseases. The declined activity or inefficient assembly of the proteasome in aging process exacerbate collapsing of proteostasis further.
(Miranda M, 2007). Defects in this mechanism can lead to various diseases, including neurodegenerative disorders, cancer, viral infection, and inflammation. Hence, it has been a fascinating field for developing cancer targets and biomarkers. b.

Traditionally used as anti-cancer drugs for their anti-inflammatory effects, proteasome inhibitors are now being recognized for their therapeutic potential in this area.

Carfilzomib doesn’t become resistance to the tumor cell compared to bortezomib due to this reason this drug was synthesized for better treatment for cancer. The process of this drug is similar to bortezomib in some way, it is capable to delay proliferation and induce apoptosis to malignant plasma cells due to the selectivity and irreversible of the inhibition of proteasomes [27]. The administration for carfilzomib is through intravenous

encode short-lived nuclear proteins with 4 conserved motifs, referred to as domain I,II,III, and IV. Domain II contains the degron motif; a sequence of 13 amino acids that play a role in the destabilization of Aux/IAA proteins and are the target in proteasome specific degradation. TIR1 contains a series of leucine rich repeats (LRR) and an F-box domain. (fig 2) This motif is often present in regulatory proteins in other eukaryotes. In Arabidopsis, TIR1 binds to Aux/IAA repressor proteins in the presence
Angelman Syndrome (AS) is a neurodevelopmental disorder, which is caused by mutations or deletions of the UBE3A gene inherited from the maternal allele. This gene encodes the protein E3 ubiquitin ligase. UBE3A is expressed biallelically in majority of tissues but in most neurons the maternal allele is solely expressed. In 1965 Dr. Harry Angelman an English pediatrician first described Angelman syndrome. At the time of discovery Dr. Angelman named the disorder “happy puppet syndrome” this was due
Cystic Fibrosis is an autosomal recessive condition with roughly 1 in 30 Americans being carriers and 30,000 having the disease itself [1]. Its cause, generally speaking, is a mutation with a protein known as Cystic Fibrosis Transmembrane Conductance Regulator (CFTR.) Normally the CFTR protein is folded with the help of chaperone proteins, checked for mutaions by the endoplasmic reticulum and then moved to the apical surface of epithetical cells where it channels chloride ions out of epithelial
Angelman Syndrome is a rare genetic disorder characterized by neurological and developmental issues. Dr. Harry Angelman discovered the syndrome in 1965. It was formerly called “Happy Puppet Syndrome” due to the clinical features possessed by those affected. Dr. Angelman observed those affected as appearing normal upon birth but eventually showing signs of development disabilities. Angelman Syndrome mainly targets the nervous system and can be detected in infants as early as six months. Typically
CREB-1 (Ca2+/cAMP response element binding protein-1) Ca2+/cAMP response element binding (CREB-1) protein is a transcription factor that regulates cell growth, homeostasis and survival. A TM phosphorylates CREB at Ser111 in response to IR. This, in turn, triggers CK-2 dependent phosphorylation of Ser108 and CK1 dependent phosphorylatio~ ofSer114 and Ser117. The phosphorylation of Ser 114 and Ser 117 by CK1 renders CREB permissive for ATM dependent phosphorylation at Ser121 (Shanware et al., 2007)
Multiple Myeloma What is Multiple Myeloma? Multiple myeloma, also known as myeloma, hematologic cancer, or cancer of the blood is a plasma cell cancer, a type of white blood cell made in the bone marrow that is responsible for creating antibodies. A Multiple myeloma diagnosis means a group of these plasma cells has become cancerous and is multiplying. This cancerous multiplication of plasma cells raises the the level of abnormal proteins in circulating blood, and reduces the space available in the
Introduction to Microbiology Pathogen paper Vibrio cholera Nazarbayev University Taxonomy and Morphology Vibrio cholerae is a gram-negative bacterium which is causative agent for the diarrheal disease cholera. Vibrio cholerae is a member of the Vibrionaceae family, which is a facultative anaerobic and is capable of respiratory and fermentative metabolism. It does not form spores and its motility is due to the single polar flagellum. Vibrios are highly halophylic and are very sensitive
The mainspring of medicine, be it Western or Aboriginal, is caring for the well-being of others. The very ethics of caregiving thrives upon beneficence. Derived from the Latin word “bene” (meaning “good”), beneficence is defined as promoting the patient’s good or welfare. The nursing knowledge and skills that health care professionals apply must ensure that beneficence comply with maleficence – that which pertains to the non-infliction of harm. This practice takes the form of removing or preventing
Kaylee Laub Von Hippel-Lindau Syndrome Disease Overview Von Hippel-Lindau (VHL) syndrome is a rare autosomal dominant genetic disorder that occurs in about 1 in every 35,000 births (Mahon, Suzanne M., 2012). The first reports on VHL syndrome were published in medical literature about a century ago where Treacher Collins and Eugene von Hippel were the first to describe families that had blood-vessel tumor development in the retina (Kaelin, William G., 2002). Later on Arvind Lindau, a neuropathologist
