In a typical experiment, mrna expression profiles are generated for thousands of genes from a collection of samples belonging to one of two classes, for example, tumors that are sensitive. Resistant to a drug. The genes can be ordered in a ranked list. L, according to their differential expression between the classes. The challenge is to extract meaning from this list. A common approach involves focusing on a handful of genes at the top and bottom. L (i.e., those showing the largest difference) to discern telltale biological clues. This approach has a few major limitations.

Contributed by Eric. Lander, august 2, 2005. Abstract, although genomewide rna expression analysis has become a routine tool in biomedical research, extracting biological insight from such information remains a major challenge. Here, we describe a powerful analytical method called Gene set Enrichment Analysis (gsea) for interpreting gene expression data. The method derives its power by focusing on gene sets, that is, dissertation groups of genes that share common biological function, chromosomal location, or regulation. We demonstrate how assignment gsea yields insights into several cancer-related data sets, including leukemia and lung cancer. Notably, where single-gene analysis finds little similarity between two independent studies of patient survival in lung cancer, gsea reveals many biological pathways in common. The gsea method is embodied in a freely available software package, together with an initial database of 1,325 biologically defined gene sets. Genomewide expression analysis with dna microarrays has become a mainstay of genomics research ( 1, 2 ). The challenge no longer lies in obtaining gene expression profiles, but rather in interpreting the results to gain insights into biological mechanisms.

If you want to identify the spots in the mixture, you obviously can't do it with comparison substances on the same chromatogram as we looked at earlier with the pens or amino acids examples. You would death end up with a meaningless mess of spots. You can, though, work out the Rf values for each of the spots in both solvents, and then compare these with values that you have measured for known compounds under exactly the same conditions. Intuitive and easy to use, use quantum xl to create and update control charts directly in Excel. Variable and attribute data, custom out-of-control checking.

In the diagram, the position of the solvent front is marked in pencil before the paper dries out. This is labelled as SF1 - the solvent front for the first solvent. We shall be using two different solvents. If you look closely, you may be able to see that the large central spot in the chromatogram is partly blue and partly green. Two dyes in the mixture have almost the same Rf values. They could equally well, of course, both have been the same colour - in which case you couldn't tell whether there was one or more dye present in that spot.


What you do now is to wait for the paper to dry out completely, and then rotate it through 90, and develop the chromatogram again in a different solvent. It is very unlikely that the two confusing spots will have the same Rf values in the second solvent as well as the first, and so the spots will move by a different amount. The next diagram shows what might happen to the various spots on the original chromatogram. The position of the second solvent front is also marked. You wouldn't, of course, see these spots in both their original and final positions - they have moved! The final chromatogram would look like this: Two way chromatography has completely separated out the mixture into four distinct spots.

In this example, the mixture contains the amino acids labelled as 1, 4 long and. And what if the mixture contained amino acids other than the ones we have used for comparison? There would be spots in the mixture which didn't match those from the known amino acids. You would have to re-run the experiment using other amino acids for comparison. Two way paper chromatography, two way paper chromatography paper gets around the problem of separating out substances which have very similar Rf values. I'm going to go back to talking about coloured compounds because it is much easier to see what is happening. You can perfectly well do this with colourless compounds - but you have to use quite a lot of imagination in the explanation of what is going on! This time a chromatogram is made starting from a single spot of mixture placed towards one end of the base line. It is stood in a solvent as before and left until the solvent front gets close to the top of the paper.

In the diagram, the mixture is m, and the known amino acids are labelled 1. The position of the solvent front is marked in pencil and the chromatogram is allowed to dry and is then sprayed with a solution of ninhydrin. Ninhydrin essay reacts with amino acids to give coloured compounds, mainly brown or purple. The left-hand diagram shows the paper after the solvent front has almost reached the top. The spots are still invisible. The second diagram shows what it might look like after spraying with ninhydrin. There is no need to measure the Rf values because you can easily compare the spots in the mixture with those of the known amino acids - both from their positions and their colours.

of course - you could have two similarly coloured compounds with very similar Rf values. We'll look at how you can get around that problem further down the page. What if the substances you are interested in are colourless? In some cases, it may be possible to make the spots visible by reacting them with something which produces a coloured product. A good example of this is in chromatograms produced from amino acid mixtures. Suppose you had a mixture of amino acids and wanted to find out which particular amino acids the mixture contained. For simplicity we'll assume that you know the mixture can only possibly contain five of the common amino acids. A small drop of a solution of the mixture is placed on the base line of the paper, and similar small spots of the known amino acids are placed alongside. The paper is then stood in a suitable solvent and left to develop as before.

The diagram shows what the plate might look like after the solvent has moved almost to the top. It is fairly easy to see from the final chromatogram that the pen that wrote the message contained the same dyes as pen. You can also see that pen 1 contains a mixture of two different blue dyes - one of which might be the same as the single dye in pen. Rf values, some compounds in a mixture travel almost as far as the solvent does; some stay much closer to the base line. The distance travelled relative to the solvent is a constant for a particular compound as long as you keep writing everything else constant - the type of paper and the exact composition of the solvent, for example. The distance travelled relative to the solvent is called the Rf value. For each compound it can be worked out using the formula: For example, if one component of a mixture travelled.6 cm from the base line while the solvent had travelled.0 cm, then the Rf value for that component is: In the example.

The paper is suspended in a container with a shallow layer of a suitable solvent or mixture of solvents. It is important that the solvent level is below the line with the spots. The next diagram doesn't show details of how the paper is suspended because there are too many possible ways of doing it and it clutters the diagram. Sometimes the paper is just coiled into a loose cylinder and fastened with paper clips top and bottom. The cylinder then just stands in the bottom of the container. The reason for covering the container is to make sure that the atmosphere in the beaker is saturated with solvent vapour. Saturating the atmosphere in the beaker with vapour stops the solvent from evaporating as lined it rises up the paper. As the solvent slowly travels up the paper, the different components of the ink mixtures travel at different rates and the mixtures are separated into different coloured spots.
