ALK (Anaplastic lymphoma kinas) is part of the leukocyte kinase receptor superfamily. It is made up of three different domains: the extracellular domain holding the N-terminal region and the ligand-binding site for pleitroplin,midkine, the transmembrane and juxtamembrane are holding thee binding site for phosphotyrosine-dependent and finally the intracellular tyrosine domain has three phosphorylation sites and the C-terminal sites for phospholipase C-gamma and Src homology 2 domain containing SHC1. ALK is responsible for the regulation of cellular growth and when mutated, translocated or overexpressed , it can lead to neoplastic transformation2. To slow down the neaoplastic transformation for becoming a cancer, many drugs had been designed
Optimal management of NSCLC now requires that tumours be screened for a certain range of predictive and prognostic biomarkers that help to predict sensitivity to targeted therapy and estimate prognosis respectively . For NSCLC, much of the work in the past years has been focussed on mutations of the epidermal growth factor receptor (EGFR) and on the abnormal fusion of the anaplastic lymphoma kinase (ALK) being inhibited successfully with EGFR tyrosine kinase inhibitors (TKI) and crizotinib respectively. Targeted agents are now being rationally designed to inhibit particular mutations leading to a more streamlined clinical trial process. In this review, we will examine the major subtypes of driver mutations that have been identified in NSCLC and relevant targeted therapies available both now, and in the foreseeable future.
ALPFA (Association of Latino Professionals for America)is a non-profit organization that is centered on empowering both professionals in the workforce and young student leaders. Although it states Latino's, the organization welcomes anyone as a member.
C-Akt, a serine-threonine kinase is one target of PI39K. C-Akt is the prototypical member of a mammalian Akt isoform family. The regulation to Akt may be phosphorylation or direct binding the Akt pleckstrin homology domain with PI39K lipid products. PI39K-independent Akt stimuli had been identified [3]. AMG 319 inhibited basal AKT phosphorylation and proliferation in lymphoid tumor cells [1].
Earmarks are not entirely a modern invention. They have been around for more than two centuries. The first earmark was used in the Lighthouses Act of 1789. Earmarks are legislative provisions that direct previously set aside funds to be spent on specific projects. They are not extra spending, because the money appropriated is previously allocated for spending. Earmarks helped “grease the wheels of democracy” by giving leadership to induce rank-and-file members to cast tough votes (Schlesinger). This wasn’t their only purpose though. Earmarks also helped ameliorate one of the fundamental tensions of our republican democracy. They made it easier for lawmakers to balance national and parochial interests. Earmarks also served a multitude of other
ACO, another 3 letter health care organization consisting of integrated groups of providers, comes along promising the elusive goal of reducing health care cost, improving population health, and bolstering custom satisfaction. Sounds like a perpetual remake of a 70s movie called HMO that went through several reiterations over the past decades which gave us PPO, PSO, IDS, and the different flavors of MCOs. ACO’s hype is credited to the Affordable Care Act as it sought to reduce health care costs is by encouraging doctors, hospitals and other health care providers to form networks that coordinate patient care and become eligible for bonuses when they deliver that care more efficiently. Bottom line, providers are promised to make more if they
CD117 is a membrane tyrosine kinase receptor (Type III receptor tyrosine kinase family), encoded by the c-kit proto-oncogene. The Type I transmembrane glycoprotein locates on chromosome 4q11 and 4q12 and has a total length of 90 kb. It has a molecular mass of 145 kDa. The extra-cellular domain consists of 519 amino acids. It contains 5 Ig-like domains. D1-D3 are responsible for c-kit binding to stem cell factor, and D4 and D5 are the dimerization domains. The transmembrane region consists of 23 amino acids and the juxta-membrane domain is made up of 433 amino acids. The tyrosine kinase domain is inserted by approximately 80 amino acid residues.
1. “No one had declared war since World War II” stated, Gregory Johnson in the Podcast, 60 Words. At the attacks on September 11, 2001, the Congress as asked, once again, to grant the President the authority he would need to defense the United States. That authorized came for legislation titled, 2001 Authorization to Use Military Force or AUMF. This document authorized the President to use all necessary force against the any groups believed to be responsible for the attacked on September 11, 2001. The vote passed, 420 to 1, and President Bush signed the AUMF on September 18, 2001. The only vote of “no” was casted by Senator Barbara Lee of California. While delivering the vote, Senator Lee said, “Some of us must urge the use of restraint.”
The main focus of this article was to Crizotinib as an inhibitor for ALK-rearragements in the Non-Small Cell Lung Cancer (NSCLC). The drug was first developed because of the ability for a diagnostic fluorescent in situ hybridization assay to be used to detect ALK-rearranged NSCLC. Pfizer has developed this drug to inhibit ALK and MET in many cancers that are associated with mutations in these specific genes. It has recently been shown to have an effect against ROS1-rearragements in NSCLC. This article provided better insight on the heterogeneity between ALK and ROS1 rearrangements in different subtypes of NSCLC. There is also information in the research article that sheds light into the future developments for crizotinib for ALK-rearrangements and some diagnostic assays that can detect NSCLC. This drug is important to the future of cancer therapies because it targets a subtype to NSCLC and defines a molecular target for its effectiveness. It can broaden a field which involves personalized therapies
The additional member system, like every other electoral system has both advantages and disadvantages. Which of these outweighs the other remains debatable. The additional member system is described as a type of PR (proportional representation) system where the number of votes is equal to the number of seats gained. The AMS is a hybrid system with two votes and two systems mixed together, the first vote being your constituency vote and the second, the regional vote. There are 129 members of the Scottish parliament and there are two ways an MSP can be elected. Scotland is divided into 73 constituencies and each constituency elects one MSP. These are known as
Page 1 Hello! My name is Alex. I am a nineteen year old girl who is about to bring you through my journey of a disease I never imagined would happen to me, well at least at this age. Three days into my nineteenth birthday I was diagnosed with Hodgkin’s lymphoma. If you don’t know what that means, as I didn’t the first time I was told it is the dreaded C word.

As the world continues to suffer from these devastating diseases, researchers continue to find alternative therapeutic ways of addressing cancer treatment. It is on this premise that various immunotherapeutic alternatives have emerged and currently garnering the greatest level of attention and already raising hope throughout the world in addressing the treatment of NSCLC. However, this can no longer be viewed as a discovery but a wave in the medicine world that began in the 20th century. Various researchers have found the importance of the role of immune systems in fighting the growth of tumor caused by cancer cells. A study by Huncharek (2000) stated that specific immune boosters are capable of eliminating preclinical cancers. In contrast, Jermal et al. (2011) found that immunotherapy is an effective approach for the treatment of tumors that have already turned into solid. Similarly, the researchers highlighted that immunotherapy can be an effective approach to the treatment of melanoma as well as renal cell cancers (Lasalvia-Prisco, 2008). However, Jemal et al. (2011) noted that immunotherapy cannot achieve much in cancer treatment due to limitation brought about by the emission of immunosuppressive cytokines and subsequent loss of antigen expressions. Recent development in research studies on the immunotherapy approach to cancer treatment continues to elicit mixed reactions among researchers of medicinal ecology (Jadad et al., 1996). However, recent development in
In addition, FMS-like tyrosine kinase-3 receptor expressed in most acute lymphoblastic leukemia cells and acute myeloid leukemia(Drexler, Meyer et al. 1999). FMS-like tyrosine kinase-3 receptor mutations are identified in about 30% of the adult with acute myeloid leukemia, and leukocytosis and poor prognosis(Rasko, Metcalf et al. 1995, Kiyoi and Naoe 2002, D Kottaridis, Gale et al. 2003, Levis and Small 2003, Stirewalt and Radich 2003, Naoe and Kiyoi 2004, Kiyoi, Yanada et al. 2005). In normal bone marrow, expression appears to be restricted to early progenitors, includingCD34_ cells with high levels of expression of CD117 (c-KIT)(Rasko, Metcalf et al. 1995, Drexler 1996, Kiyoi, Yanada et al. 2005). FMS-like tyrosine kinase-3 receptor is also expressed at high levels in a spectrum of hematologic malignancies including 70% to 100% of myelogenous leukemia of all French-American British subtypes-precursor cell acute lymphoblastic leukemia , a fraction of T-cell acute lymphoblastic leukemia, and chronic myelogenous leukemia in lymphoid blast crisis(Mackarehtschian, Hardin et al. 1995, Kiyoi, Yanada et al. 2005).
