In a lems, but to do that, we need to understand the causes. Steve Elliott Telephone: In studies that are not reproducible, experiments may be E-mail address: EPO is a glycoprotein hormone produced by the kidney that repeated is the primary regulator of erythropoiesis, red blood cell formation.

Sub- sequently, numerous publications appeared suggesting EPOR was widely and highly expressed in cancer cells and that ESAs promoted false-positive and false-negative results. Alternatively, the strate- tumor cell growth and survival in vitro. This proposal was disputed gies used may promote questionable conclusions.

These may be according to other studies suggesting that ESAs had a singular effect used because other more effective measures failed. For example, on erythropoiesis and that EPOR was expressed exclusively in the experiments may be performed that generate indirect evidence.

Correlations To evaluate the quality of the work around this hypothesis, a may be found that are merely statistical aberrations. The methods and results correlations does not mean there is a causal relationship.

In addition, reagents one or more of the following: Berglund et al. Antibodies more of the tests Fig. The author conclusions were divided into are the workhorse of many studies, yet the antibody reagent 2 categories; articles supported the EPOR-cancer hypothesis problem is not appreciated.

It is important to note that this analysis process, and bad science is published. Subsequent correction of does not address the EPORdcancer question per se; other infor- errors may not occur when there is too much trust in the publi- mation is required.

However, it does raise concerns about the cation record.

Symptoms of this bias are selective reporting of, or even falsifying of data. There is also selective citing of supportive references. Of particular concern is when authors vigorously defend their articles in the face of mounting evidence against their positions. Articles early as Thus, a single positive result might have a direct effect on promoting cancer cell growth or survival. In addition, examined to see if they included EpoR-positive and -negative control cell types, used journals favor publication of positive and novel results.

Those failing one or more of those criteria were usually supportive of the popular view, which provides a disin- considered questionable. The number of articles whose conclusions supported the centive to perform repeat experiments.

Thus, positive results are EpoR hypothesis and those that were neutral or didn't support the hypothesis are more likely to be published, and remain unchallenged. However, there must be evidence that the band 2 experiments that showed positive, but mixed effects. In the latter detected was EPOR, and this was not evident in most articles.

Despite these problems, Santa Cruz Inc. However, the anti- westerns. As shown in Figure 2, in only failed. None of the arti- results. In control ex- reported no effect of ESAs.

In periments were negative. In a few cases, putative positive controls as phosphorylated AKT and ERK, but trivial manipulations such as a were included, for example placenta, but there was no independent media change or addition of low levels of serum or BSA activate demonstration that those expressed EPOR. The authors declared those molecules,30 making them susceptible to false positives.

Those articles ESAs in tumor cells, indirect strategies were used. For example, did not validate the tissues for EPOR expression either. Editors and reviewers should insist on more complete release of methods and reagents, with a disclosure of how the reagents were validated.

All experiments must include both positive and negative controls, with evidence that those are also validated. We all need to look in the mirror and make sure we are doing Figure 2. Quality of anti-EpoR antibody data in EpoR and cancer articles. One hundred good science before assuming that the problem lies elsewhere. Those articles were examined to see if should not cite an article they have not read in detail with meth- they included EpoR-positive and -negative control cell types and whether the correct odologies or results they do not understand.

Those failing one or more of those criteria were considered questionable. The number of articles whose conclusions supported the our hypotheses might be wrong if there is internal or external EpoR hypothesis and those that were neutral or didn't support the hypothesis are discordant data. It is important to do experiments that might shown. Scientists must spend more time and effort doing Mol Cell Proteomics.
