Scientists Spot Cancer Metabolism Changes

News Picture: Scientists Spot Cancer Metabolism Changes

SUNDAY, April 21 (HealthDay News) -- Hundreds of potential targets for new cancer drugs that could starve tumors have been identified by scientists who analyzed gene expression data from 22 types of malignancies.

The study revealed a number of cancer-associated changes in the metabolism of cells. To support their uncontrolled growth, cancer cells need to reprogram and "supercharge" a cell's normal metabolism, the researchers explained.

Pinpointing these metabolic changes could prove important in efforts to develop drugs that interfere with cancer metabolism, according to the study, which was published online April 21 in the journal Nature Biotechnology.

"The importance of this new study is its scope," lead investigator Dennis Vitkup, an associate professor of biomedical informatics at Columbia University Medical Center, said in a center news release. "So far, people have focused mainly on a few genes involved in major metabolic processes. Our study provides a comprehensive, global view of diverse metabolic alterations at the level of gene expression."

One of the major findings was that cancer-induced changes in metabolism are significantly different in various types of tumors.

"Our study clearly demonstrates that there are no single and universal changes in cancer metabolism," study co-author Dr. Matthew Vander Heiden, an assistant professor at MIT, said in the news release. "That means that to understand transformation in cancer metabolism, researchers will need to consider how different tumor types adapt their metabolism to meet their specific needs."

Targeting metabolism may be a way to strike cancer at its roots, according to Vitkup.

"You can knock out one, but the cells will usually find another pathway to turn on proliferation. Targeting metabolism may be more powerful, because if you starve a cell of energy or materials, it has nowhere to go," he explained.

Metabolism Down From Eating Disorder

I had an eating disorder from about 2010 to 2012. During that time period my weight was around 117 (I'm 5' 4''). I lost my period and a lot of my hair fell out. I only at around 700 calories a day maximum. I didn't feel any hunger at all.

I started eating 2000 calories a day since August 2012. It's almost been a year of me eating 2000 calories a day and my weight is now at 150 pounds. My hair has stopped falling out and I got my period back. However, I still don't feel hunger. My metabolism seems to not have changed at all since my eating disorder. Does anyone have any advice for me? It's getting really frustrating since I'm now "slightly overweight."

want to maintain and boost metabolism

I recently lost some weight by restricting my calories too low. I want to start maintaining (happy at my current weight) but I also would like to boost my metabolism so I am maintaining on a more normal amount, and because I definitely have damaged my metabolism by restricting for 4 months!

I know gaining muscle and exercising is a good way, but I struggled with overexercising in the past, and due to injury, I am advised not to run. I like taking walks, and I stand a lot at work, but other than that, I try not to do too much FORMAL exercise because I get VERY obsessive-compulsive about it very quickly. I love this new freedom I have by not feeling forced to exercise, and I don't want to jeopardize it by starting a new program.

Basically my goal is to choose healthy foods (ex, a 400kcal meal for dinner instead of 400kcal of ice cream) and keep an eye on my calories, but should I risk raising my intake and possibly gain weight?

Right now I eat about 1400-1600/day and am more or less maintaining, although I feel like 1700-1800 is more reasonable for a girl my age, not to mention that I get quite hungry throughout the day and that shaky-hypoglycemic feeling (18 yrs, 5'5", 117 lbs).

Can you repair your metabolism

I'm 16 and ate 800-1200 calories for about a half year now. I know I've probably basically destroyed my metabolism. I excercise at the very least, an hour a day. Is it possible to repair a damaged metabolism? Or am I ruined for life.

measuring resting metabolism

I got a Bodymedia armband this weekend and am curious whether I can use it to estimate my resting metabolism. It seems that I burn about 63 cal/hr when I'm sleeping, which is about 1500 cal/day with no activity. Does this sound about right? I'm 42, F, 5'7", 130 lbs. Also, how would this relate to my basal metabolism?

Thanks!

Can You Really Boost Your Metabolism?

I hear comments all the time like, “How do I raise my metabolism,” or “I guess I just have a slow metabolism,” and the ever popular, “Can I boost my metabolism?”

Right off the bat, I need to let you know that claiming to be a victim of a slow metabolism is no excuse for being overweight. I mean, if you’re scarfing down Arby’s and then say your round midsection is because you have a sluggish metabolism, you not foolin’ anybody. Take an honest look at your habits and stop hiding them behind a feigned effort.

So, what is metabolism exactly? Well, it’s a pretty sophisticated process that involves hormones and enzymes. It basically determines the rate that we burn calories, amongst other things. So, the annoying folks who can eat everything in sight and not gain an ounce of fat usually have a high metabolism to partially thank.

There are things that affect your metabolism that you can’t do anything about. Heredity is one. Genetic factors can help determine your rate of metabolism. But, remember, this just means a “predisposal” to a particular type of metabolism. Don’t go hiding behind Momma and Papa if you’re overweight.

Age is another thing that can affect your metabolism. For each decade after age forty, your metabolism slows by about 5 percent. Really, that’s not that much when you think about it. So, if you’re getting up there in years, you really can’t use your age for your reason why body fat is steadily accumulating.

And, gender is another thing that will affect your metabolism. Guys have a slight advantage in this one. Men burn more calories at rest that women. However, all these things are just innate qualities that we can’t change. So our focus shouldn’t be on them. We need to focus on the things we can change, and then head down that road.


Muscle

Well, the more lean mass you have, the more calories you burn. This equates into a higher metabolism. So, yes, it’s scientifically accurate to say that the more muscle you have, the more calories you’ll burn.

Muscle burns more calories that fat. Every pound of muscle you have burns about 35 calories a day. Every pound of fat you pack, on the other hand, burns a mere 2 calories day. So the difference is pretty significant.

Meal Timing

Yes, we’ve all heard that you should space your meals out throughout the day. This does help avert hunger and possible prevent binging. But, it also keeps our metabolic system running smoothly.

I’m not saying it’ll kill you to eat three squares a day, but if you can spread out your meals to every three hours or so, you’ll let your body know –

“Things are running just fine. Keep burning, Baby.”
The end result of taking the time to space out your meals will be a higher metabolism and a reduction in caloric intake. This means more fat loss.


Certain Foods

Okay the evidence is pretty sketchy on foods having an impact on your metabolism. I mean, yes, certain foods definitely do impact metabolic rate, but the degree in which they do that is pretty minimal.

I’m not complaining, though. How hard is it to throw in more food in my diet? Plus, the kinds of foods that might boost your metabolism are pretty tasty.

Lean protein. You’ve probably already eating a bunch of this, already. Healthy meats, low-fat cottage cheese, fage, etc. They move through the digestive system pretty slowly, so they help you feel full longer. They also take a good amount more energy to digest then carbs. More energy expenditure is what you’re after, so make sure to eat some good protein every few hours.

Spicy Stuff. Every time you eat something spicy, your metabolism raises for a short time. It’s the capsicum that does it. The effect is minimal, but if you like spicy foods, you can use this trivia to your advantage.

Precision NutritionPersonally, I’m a huge fan of spicy foods. Now I have an excuse to offer people when I get the odd look as I take hot sauce out of my purse. Jeez. Am I the only lady who never leaves home without her Tabasco or Cholula?

But, I don’t think researchers have paid enough attention to the other effects spicy food can have on dieters. Think about it. When you eat hot foods, you usually end up guzzling a lot more water. And more water, as we all know, means more satiety and more fat loss.

Not only is there the issue of water, but there is also that revved up feeling you get after eating something spicy. Eat a hot pepper. What happens? You get kind of fired up, and eating heavy foods after that doesn’t seem very appealing, right? Hail, hot peppers!

Green Tea. Green tea has a specific antioxidant, EGCG, that may speed up your metabolic rate. But, again, the impact is pretty minimal. So, if you like green tea, go ahead and guzzle away. If you’re not fond of it, you’re really not missing out on much in terms of metabolic effects.


1. Pack on muscle. You know what to do.

2. Spread out meals to every 2-3.5 hours

3. Eat lean protein at each of these meals

4. Throw in some hot stuff and green tea

No more excuses. Life is what you make it. Sluggish metabolism is a sorry excuse. Raise it. Work your butt off and do all you can do. You’ll improve dramatically. Burn, Baby, Burn!

You can really Boost your metabolism?

I hear the comments all of the time like, "how I raise my metabolism," or "I guess I'll just have a slow metabolism," and the ever popular, "can I boost my metabolism?"

Right off the bat, I must let you know that claims to be a victim of a slow metabolism is no excuse for being overweight. I mean, if you're scarfing down your round belly is Arby's and then say that because you have a slow metabolism, you not foolin' anybody. Take a honest look your habits and stopping them hiding behind a feigned effort.

They also take a good amount of more energy to digest than carbohydrates. More energy expenditure is what you're after, so make sure to eat some good protein every couple of hours.

Spicy stuff. Every time you eat something spicy, increases your metabolism for a short time. It is the "Capsicum" that it does. The effect is minimal, but if you spicy foods, you can use trivia to your advantage.

Precision NutritionPersonally, I'm a big fan of spicy food. Now I have an excuse to offer people when I get the odd look as I take hot sauce from my bag. Jeez. Am I the only lady who never leaves her house without Tabasco or Cholula?

But, I don't think researchers have enough attention to the other effects on spicy food dieters can have. Think about it. If you eat hot food, which you usually end up guzzling much more water. And more water, as we all know, means more saturation and greater fat loss.

Not only is there the issue of water, but there is also that feeling you get after eating something spicy revved. Eat a hot pepper. What is going on? You kind of fired up, and eat heavy foods after that seems not very attractive, right? Hail, hot peppers!

Green tea. Green tea has a specific antioxidant, EGCG, which can speed up your metabolism. But, again, the effect is pretty minimal. So, if you're green tea, go ahead and drown road. If you're not fond of, yours really doesn't lack a lot in terms of metabolic effects.


1. suit on muscle. You know what to do.

2. meals Distributed to each 2-3.5 hours

3. eat lean protein on each of these meals

4. throw in some hot stuff and green tea

No more excuses. Life is what you make it. Slow metabolism is a sad excuse. Raise. Work your ass off and doing everything that you can do. You will improve dramatically. Burn, Baby, Burn!
