Ki67 is a protein found in the nucleus of dividing cells and therefore necessary during cellular proliferation. The protein can be found in all phases of the cell cycle but not in resting cells. The Ki67 staining is used to determine growth of certain cell types and is therefore used on hyperproliferative cells such

This means that copies of RNA will not be created and this will limit the amount of certain proteins and enzymes available during critical times in development and growth. http://www.youtube.com/watch?v=erOP76_qLWA&feature=related The dogma of molecular biology entails the transcription of genetic information from DNA onto RNA and the translation of these mRNA messages into proteins and enzymes. It is the function of RNA polymerase‚ to copy the genetic message to messenger RNA as

Brain Mechanisms of Fear Extinction: Historical Perspectives on the Contribution of Prefrontal Cortex Francisco Sotres-Bayon‚ Christopher K. Cain‚ and Joseph E. LeDoux What brain regions are involved in regulating behavior when the emotional consequence of a stimulus changes from harmful to harmless? One way to address this question is to study the neural mechanisms underlying extinction of Pavlovian fear conditioning‚ an important form of emotional regulation that has direct relevance to the treatment

Most of the cardiac injury ultimately results in development of cardiac fibrosis due to negligible regenerative capacity of heart. Cardiac fibrosis is associated with increased deposition of matrix proteins in the myocardium. The expansion of the cardiac interstitial space in absence of significant cardiomyocyte loss is “reactive interstitial fibrosis” and the formation of scar in response to myocardial infarction is called “reparative fibrosis” [10‚ 46]. Increased deposition of endomysial and perimysial

There are several types of staining through which the bacteria can be identified based on the color and shape. The staining methods used in the lab are Gram Staining‚ Capsule Staining‚ Endospore Staining‚ and Acid Fast staining. One of the most significant method of

The HeLa and HepG2 cells were exposed to Pierisin-6 protein (2 and 25 ng/ml‚ respectively) for different time intervals (6‚ 2‚ 24‚ 36‚ 48 and 72 h) and the activation of Caspases-3 were detected. Caspase-3 activity increased significantly after Pierisin-6 treatment when compared with untreated cells (Fig.
