Strange behavior: new study exposes living cells to synthetic protein

One approach to understanding components in living organisms is to attempt to create them artificially, using principles of chemistry, engineering and genetics. A suite of powerful techniques—collectively referred to as synthetic biology—have been used to produce self-replicating molecules, artificial pathways in living systems and organisms bearing synthetic genomes. In a new twist, John Chaput, a researcher at Arizona State University’s Biodesign Institute and colleagues at the Department of Pharmacology, Midwestern University, Glendale, AZ have fabricated an artificial protein in the laboratory and examined the surprising ways living cells respond to it. “If you take a protein that was created in a test tube and put it inside a cell, does it still function,” Chaput asks. “Does the cell recognize it? Does the cell just chew it up and spit it...

New Data Challenge Old Views About Evolution of Early Life

A research team led by biogeochemists at the University of California, Riverside has tested a popular hypothesis in paleo-ocean chemistry, and proved it false. The fossil record indicates that eukaryotes — single-celled and multicellular organisms with more complex cellular structures compared to prokaryotes, such as bacteria — show limited morphological and functional diversity before 800-600 million years ago. Many researchers attribute the delayed diversification and proliferation of eukaryotes, which culminated in the appearance of complex animals about 600 million years ago, to very low levels of the trace metal zinc in seawater. As it is for humans, zinc is essential for a wide range of basic cellular processes.  Zinc-binding proteins, primarily located in the cell nucleus, are involved in the regulation of gene transcription. Organic-rich shale samples, such...

We come across many students who have lots of business ideas during their graduation days, about opening their own business and a dream of being the Boss /CEO of their own company. But with time, these ideas get cornered and a person ends up finding a good job or takes up higher studies etc, but very few have the courage to start...

CSIR UGC NET(Life Sciences)

This post is dedicated to all the NET aspirants who will be taking the test this Sunday i.e. the 23rd December 2012.  We hope you are all geared up and ready to rock the test. CSIR NET exam is really a tough one and thousands of aspirants desire to crack it. It needs a thorough preparation which you all must be done with by now and a well planned strategy for taking the exam. Here in this post we will be providing you some tips about CSIR UGC NET. 1. The first suggestion to all is to keep a check on the CSIR HRDG website always, even after you have taken the exam. For instance the timings of the exams was changed as given here. 2. Try doing a lot of question papers of the previous NET exams, as many as possible. This helps in improving your speed which is a crucial factor when one is attempting the questions in very limited time. In addition to that, it helps in preparing a strategy which you are most likely to follow in your exam to manage your time between questions (not all questions need to be attempted) and obtain the maximum efficiency and as a consequence the maximum marks. 3. Work on your strong topics very exhaustively. Since only 15/20, 35/50 and 25/75 questions need to be done, it will help you to decide the questions quickly thus saving a lot of time. In other words you should have complete knowledge of the topic you are very good at. 4. Never answer the questions randomly. Answer only if you are sure of the answer. Sometimes categorizing the questions into 3 categories, absolutely sure ones, doubtful ones and the ones with no idea; is helpful. This way you can attempt the first category and only if the required number...

Designing Influenza Immunogen

Influenza HA is the primary target of neutralizing antibodies during infection, and its sequence undergoes genetic drift and shift in response to immune pressure. The receptor binding HA1 subunit of HA shows much higher sequence variability relative to the metastable, fusion-active HA2 subunit, presumably because neutralizing antibodies are primarily targeted against the former in natural infection. We have designed an HA2-based immunogen using a protein minimization approach that incorporates designed mutations to destabilize the low pH conformation of HA2. The resulting construct (HA6) was expressed in Escherichia coli and refolded from inclusion bodies. Biophysical studies and mutational analysis of the protein indicate that it is folded into the desired neutral pH conformation competent to bind the broadly neutralizing HA2 directed monoclonal 12D1, not the low pH conformation observed in previous studies. HA6 was highly immunogenic in mice and the mice were protected against lethal challenge by the homologous A/HK/68 mouse-adapted virus. An HA6-like construct from another H3 strain (A/Phil/2/82) also protected mice against A/HK/68 challenge. Regions included in HA6 are highly conserved within a subtype and are fairly well conserved within a clade. Targeting the highly conserved HA2 subunit with a bacterially produced immunogen is a vaccine strategy that may aid in pandemic preparedness. Read the full study here. A summary is given here. ...
