The observation that prostate cancer metastasis to bone is associated with increased osteoblast activity is supported by the finding that serum levels of markers of osteoblast proliferation, such as bone-specific alkaline phosphatase, are increased in patients with metastatic prostate cancer.
Mostly, animals get eaten by lions, not the other way around. Thatâs because lions are at the top of their food chain, and at the very center of their food web. Lions have almost no predators. However, old, sick lions are sometimes attacked, killed and eaten by hyenas. And very young lions can be killed by hyenas, leopards and other predators when they are not being watched carefully by their mothers. But a healthy adult lion has little to fear from any other animal.
Mountain lions have been a part of the ecosystem of the Front Range of Colorado for thousands of years. They are large predators feeding mainly upon deer. Lions have proven to be adaptable and can live on lands adjacent to cities as long as they have ample prey and places to rest and hunt.hey can also eat mice, rabbits, squirrels, porcupines, raccoons, coyotes and grasshoppers. A mountain lion will generally not eat carrion. Domestic livestock may be hunted and consumed. Contrary to popular myth, lions don't sit in trees and jump down on people or prey.
