Buckyball Longevity - There's A Problem

Email This Entry

Posted by Derek

We have a problem here. The paper I blogged about yesterday, on life extension effects with C60 fullerene ("buckyballs") has a duplicated figure. This was first spotted by commenter "Flatland" yesterday. I was traveling all day, and when I came home in the evening I saw the comment and immediately realized that he was right. I've made the animation below (via Picasion) to illustrate the point:
These are from the part of the paper where they showed protective effects of C60 on animals that were being dosed with (toxic) carbon tetrachloride, and these are supposed to be the water/carbon tet control animal dosed by oral gavage (GAog) and by intraperitoneal injection (GAip). In other words, these are supposed to be separate animals, but as you can see, these are, in fact, the exact same histology slide. I've scaled the GAip image up about 120% and moved the two to correct the offset, but otherwise, I've done no image processing at all. The originals are screen shots from the PDF of the paper, the top two images of Figure 4.

This is, at the very least, very sloppy work, on both the part of the authors and the editorial staff at Biomaterials. I didn't catch this one myself, true - but I wasn't asked to review the paper, either, and I can assure you that I spend more time critically studying the figures in a paper under review than one I'm writing a quick blog entry about. Under normal reading conditions, most of us don't look at histology slides in a paper while constantly asking ourselves "Is this right? Or is this just a duplicate of another image that's supposed to be something else?"

And while this image duplication does not directly bear on the most surprising and interesting results of the paper - life extension in rodents - it does not inspire confidence in those results, either. I'm emailing the editorial staff at Biomaterials and the corresponding author of the paper with this blog entry. We'll see what happens.

But Elsevier tells us they would really like to drop the prices of journals and they really really support the idea of open access but they really really really need to charge you five figures a year for your Biomaterials subscription in order to maintain high editorial standards.

Re-use of the same images could be a sloppy accident. However, I don't think you could say the same for rats that live 5 years! That's either true, or gross incompetence, or deliberate fraud.

I'd like to give the authors the benefit of the doubt, but given the image problem, as well as the seeming discrepancy between the median survival estimates and the actual data plots, well....

Hmmm... I think comment #6 nailed it.

If this were the only inconsistency in the paper, you could always blame a tired post-doc who mixed up biologic samples.

However, I have a sneaking suspicion that this was more of a "wow, the buckyballs made the rats live longer, but the histology slides don't make sense... well this slide should look like the control so I'll just...."

From the header (Biomaterials xxx (2012) 1-11), it looks like this is a pre-print. If so, maybe it's not too late to pull it from the edition before the journal goes to press while the various oddities are sorted out.

Sensational as it is, the alleged finding of this paper may well find its way into the popular press. Given the problems already pointed out fairly quickly by various contributors to this blog, this could be a disaster in the making. There's already too much science-bashing going on around climate change, evolution and vaccine safety. If this paper were published in its current flawed form, it would deservedly be ripped to shreds and no one's interests would be served, except perhaps the attorneys involved. I hope the journal acts responsibly and promptly to get this thing re-reviewed and either trashed or published with proper science.

TBH this almost happened on my last paper, duplicated figure (very similar looking graphs) got past the reviewers. Luckily I gave the whole thing a once over after I uploaded my edits. It's a pretty easy mistake to make when you're just uploading figures onto a website. This was in a quality journal, by the way - not an Elsevier printing press.

I'll go with #24 and think this is an honest mistake. Anyone who's written a manuscript with multiple contributors and many images will know that it's all too easy for mistakes to happen in any of the many, many steps involved in the back and forth between authors, then with later changes after reviews and photo editor changes, etc... In the days of hard prints it was difficult to switch one photo for another, but nowadays with electronic files it's just too easy for confusion and switches to happen. Sure, it should have been picked up by the authors or reviewers - big surprise, shit happens. I'm certain none of the commenters here have ever made a mistake, right ?

Am I reading the chronic exposure (life extension) experiment correctly?

1. Each gavage dose was 0.8 mg C60 in 1 mL olive oil. (I guess the C60 was suspended in oil, centrifuged at 5000 g for 1 hour, filtered thru 0.25 um filter and, I hope, adjusted, somehow [HPLC analysis?], to get the 0.8 mg/mL final concentration). 1 mL of suspension per dose = 0.8 mg C60.

2. The dosing schedule was daily for 7 days (d); weekly for the next 7 weeks (w); once every two weeks for the next 20 weeks (b); then stopped (due to development of tumors in a control rat, possibly induced by gavaging).

Month 1: d d d d d d d w w w
Month 2: w w w w
M3: b b
M4: b b
M5: b b
M6: b b
M7: b b
M8 to M58: no more C60

A total of 24 doses; 24 x 0.8 mg = 19.2 mg C60;
19.2 mg C60 / 720 mg/mmole = 26.7 umoles
= 1.6 x 10^19 buckyballs, TOTAL over 7 months.

The oldest rats then survived for an additional 50 months after treatment stopped?

If a 450 g rat needs 19.2 mg to almost double their lifespan, a 60 kg human only needs ~2.56 grams of C60! They started dosing rats at 10 months of age which is about 25 years old in human years.

Until further evidence is produced, I'll accept the "submitted the wrong photo" hypothesis. If it was just a mix-up, I hope others will try to reproduce this result.

I, too have had proofs come back with completely screwed up figures. The worst offenders are journals that require you to upload the figures one at a time, and those that require artificial figure names like "fig1.eps," "fig2.eps," etc.

In this case, the figure in question looks like a montage of several photographs, so it's likely that there was only one image file, prepared by the author. There are 20 photographs in the montage, so the possibility that one photo got included twice by accident is credible.

I will also note that the duplicated figures appear to be two examples of the water control group. In a case of misconduct, wouldn't you expect the screwed up figures to include the buckyball group?

I would really like for somebody that is an experienced statistician (and not just proud to have passed a medical statistics course that result in the vast medical published studies being wrong on statistics) to look at the claims raised by this paper - I find very interesting the numbers seen for only oil vs oil+C60 but IMHO those certainly do not suggest the conclusion claimed by this study!

If it's simply a duplication of figures by double loading the same file, why the offset? (They don't appear to be the same image, but two pictures of the same tissue taken with different focus points.)

Unless the authors submitted two pictures of the same tissue, either to allow the editors to choose the best one for publication or to highlight different points of the same sample, it doesn't appear to be as innocent as a simple computer mistake.

Did they really gavage the rats with 1 mL of olive oil as a carrier? Is that typical? It seems to me to the be equivalent of a human drinking a cup of olive oil.

I can remember doing testing of rats and when you washed a drug out of a central line into the rat, you had to watch your volumes. 1-2 mL of saline and rat would start foaming at the mouth from the pulmonary edema.

I have not read the actual paper, only the string of comments posted here. 200 microliters is the volume I use when gavaging mice. Adult lab strain rats are 10-20x the weight of adult lab strain mice (20g); 1ml gavage for use with the former species sound credible (but not the most conservative volume).

As highlighted in the posts above, there are other aspects of the published report that prompt serious doubt...

Having done a lot of image work I often end up with so many images of different sections of different slides that I can see this happening as a legit mixup especialy if the person who did the imaging was not active in authoring- but still its sloppy.

Question: how bad is a lab rats diet that olive oil alone vastly improves life expectancy! :)

@27. Who is going to be side tracked into trying to replicate an experiment that will take 5+ years to perform? To quote Carl Sagan "Extraordinary claims require extraordinary evidence". This paper does not match up to such criteria. I wonder whether Biomaterials was their first choice, or if they trawled it around the glamour mags first? I'd be surprised to see this study survive the test of post-publication peer review.

I've seen enough of these types of cases to be 100% sure this is not an innocent mistake. Straight copying of the same figure maybe innocent enough, but anything requiring actual image manipulation, such as re-sizing/cropping/resolution/brghtness/contrast, is usually evidence of intent to deceive. Just take a look over on for some absolute howlers!

Also, in this composite the images on pg 7 of the paper are supposed to be labelled GAog to GEog, but note GD is repeated twice, and there is no GE.
Same goes for GAip to GEip, with a typo lp for ip compounding the problem.

I suspect the person who did the image processing in photoshop was supplied with the raw data, and messed it up - and the editors focused on the printed text, and did not spot the errors in the images. Still, such sloppiness does not inspire confidence in the data in the rest of the paper.

This 2007 study is interesting as an overview:
"Medicinal Applications of Fullerenes"

What piqued my interest is the observation that fullerenes concentrate inside mitochondria....and that they have a catalytic action against ROS.

Do the fullerenes become involved in the electron transport chain in the mitochondria? Or are they just generalist ROS scavengers in the mitochondria? Either way, their action could be related in some way to the mitochondrial theory of ageing.

1: The study says they used a ".25 UM porosity filter to filter the supernatant. In my research, I have only seen .22 and .45 size filters. I suspect they mean .45 um filter. Could this be true?

2. They say to make the C60 solution, they added 50mg of C60 to 10 ml olive oil. That is only 2 teaspoons worth of olive oil!! In order to get the .8mg/ml dosage they tout throughout the study, my math says they would need to use 62.5 ml olive oil to get the .8mg/ml dosage. Am I misunderstanding something?

3. They also record weights for the rats long past the time they last mention specifically that the rats were still alive, yet the never mention that the weights are calculated using a formula (like they mention doing with their lifespans). Is is possible that the weights are real and the rats lived longer than the last reported "live" date (month 38)?

4. They say they gave the rats 1ml dosages (that would mean that they were working with 1 pound rats). They also say they gave the rats 1.7mg/kg of weight. The rats weighed various weights according to the chart. Is this an error in the report or a conventional standard?

Everyone commenting about the errors in tracking and numbers for this study seem to forget that the study was not intended for rat life extension. As they were looking for toxicity from the Buckyballs, not for life extension, so of course the data is not going to fit correctly. Mistakes are made on image uploads, and editors also make mistakes. All in all, I do not see any "smoking gun" of deceit or forgery. Just parts of a different study put together to try and explain an unforeseen outcome. Relax, take a Buckyball cocktail and post in the morning.

I noticed the same thing about the filters, I cannot find a .25 micron Millipore filter, I can find 0.025 micron.

I have emailed the author asking how he mixed the C60 and olive oil. I assume it was with a test tube rocker. 10 mL is not enough to use a magnetic stirrer.
