Background

SerpinB3/SCCA belongs to tumor-related glycoprotein antigen, also known as TA-4 antigen, which widely exists in the cytoplasm of uterine, cervical, lung and other squamous cell carcinoma, and has a high content in non-keratinized cancer cells, which is closely related to the occurrence and development of squamous cell carcinoma. In normal squamous epithelial cells, SerpinB3/SCCA inhibits apoptosis and participates in the differentiation of squamous epithelium, but participates in the physiological processes such as invasion, metastasis and recurrence of cancer cells in tumor cells. As a specific marker of squamous cell carcinoma, the concentration of SerpinB3/SCCA increases with the aggravation of the disease, and it is an important tumor marker reflecting the biological characteristics of squamous cell carcinoma. Its serum level is widely used in the diagnosis of squamous cell carcinoma of many organs and clinical evaluation of therapeutic effect.

Balls
Size: Medium
My dog loves chasing these balls. He seems to love the squeak! They fit the chuck it stick perfectly, and are great replacements for the originals that came with the stick.

Nice set of balls
Size: Medium
The squeaker quickly became my dog’s favorite ball and has replaced the fuzzy tennis balls. My dog is a nonstop fetcher and these chuck it balls are durable and fun.

Soild
Size: Medium
The orange and blue ball is perfect. Once start taken because the because the blue noisy one was a little to easy for my dog to start ripping pieces off. Will say most toys do not survive his chewing.

Aggressive chewer who loves fetch approved!!
Size: Medium, Size: Medium
I highly recommend the Chuck-It brand in general, especially for dogs with an aggressive bite. These balls are awesome and are the most durable balls I’ve bought for my 50 lbs lab mix. He has not been able to break one of them yet and we’ve had a few of the squeaky balls for months. They are a bit pricey but worth it. The one in the pic has been used for months, lives outside and you can see it’s still in great shape.
