But these molecular determinants were undefined. In an another report thapsigiargin , a sesquiterpene lactone inhibits both mammalian and malarial SERCAs. These findings led to hypothesis that artermisins interact with a region of PfATP6 that binds thapsigargin-binding cleft of malarial and mammalian SERCAs, and are the determinant of the arteminisinin.Based on the previous data and literature, the authors identified PfATP6 as a target site. Using bioinformatics the researchers compared the amino acid sequences of mammalian and malarial SERCAs, and found that the leu263 residue is unique along with few more amino acid. After identification, different mutant were constructed to determine the affinity of arteminsins towards these mutated forms to establish its role of each amino acid towards arteminsins sensitivity.To determine the role of leu263 and other amino acids in PfATP6 doain. Different mutant of PfATP6 were express in Xenopus oocyte and functionality test were performed. It was shown that in case of altered Leu263 sensitivity decreased to almost three fold. Whereas alteration of other amino acids along with leu263 lead to 10 fold decrease in sensitivity. Similarly, introduction of Leu263 in non-sensitive sps. like Plasmodium vivax and P. berghei ether increased or decreased sensitivity.
Arteminsims from sweet wormwood are known to be the important class of antimalarial drugs. Artemisinin-containing therapies have increased, but the mechanism of action of the sesquiterpene lactone endoperoxides is controversial. …
In addition, new advancements have resulted in new inquiries and questions regarding legitimacy, effectiveness, and most importantly, ethical standing of the developments that has inclined researchers and experts to carry out research, in order to analyze such aspects.
Aims and motives: The main driving force behind my choice of this course is not just my interest in the subject, but also my personal experience. Having suffered from asthma and vitiligo at an early age, I began questioning the human body and have always been curious to learn more about it.
This practical utilized the plasmid vector pUC19, a common vector used for cloning small DNA fragments in Escherichia coli. pUC19 is 2686bp in total size and contain an origin of replication that enables the given vector to replicate in E.coli. pUC19 replicates in E.coli to produce approximately 100 copies per cell.
The results indicate there is high level of WBC along with very high Erythrocyte Sedimentation Rate (ESR). Based on the patient history, back pain indicates possibility of multiple myeloma as those are the primary symptoms for the same. Multiple myeloma is one type of blood cancer where uncontrolled growth of plasma cells occurs.
The ras oncogenes are activated when the hormones stimulate the cell receptors and this in turn transmits signals to the cells to grow and vice-versa. Thus regulating the cell growth, which is an important part of the cell cycle.
Several such ras oncogenes such as H, N and K ras often undergo point mutation and resulting in sending false signal to the cells.
Various researchers investigated RAGE inhibitors as the pathogenesis reasons of causing diabetic impediments and the authors of the article have incorporated that knowledge in the introduction to make it strong. However, the shortness of the introduction is a
