Background

Ewing’s sarcoma (EWS) is a bone cancer arising predominantly in young children. EWSR1 (Ewing Sarcoma breakpoint region 1/EWS RNA binding protein 1) gene is ubiquitously expressed in most cell types, indicating it has diverse roles in various cellular processes and organ development. Recently, several studies have shown that missense mutations of EWSR1 genes are known to be associated with central nervous system disorders such as amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Otherwise, EWSR1 plays epigenetic roles in gene expression, RNA processing, and cellular signal transduction. Interestingly, EWSR1 controls micro RNA (miRNA) levels via Drosha, leading to autophagy dysfunction and impaired dermal development. Ewsr1 deficiency also leads to premature senescence of blood cells and gamete cells with a high rate of apoptosis due to the abnormal meiosis [PMID: 30481590].

Squeaks for a while
Size: Medium, Style: Squeaker
I've got probably 10 of these, now. The squeaker fails pretty quickly. But our dog still likes them, just not as much as when they squeak. I'm tossing these a good 75 yards and farther. The Chuckit glowballs make sounds through their holes so no separate squeakers there. Dog really likes those glowballs.

Great quality but the squeaker doesn't last long - still a good value
Size: Medium, Style: Squeaker
I have golden retrievers who never get tired of playing balls. These are VERY durable. No seams to split. They tend to chew as they bring the balls back, so the squeaker doesn't last long. Would highly recommend these. I have them on auto-delivery!

Highly recommend
Size: Medium, Style: Squeaker
My dog loves these! They are now his absolute favorite! The squeaker lasts a lot longer than most. The rubber isn’t hard on his teeth and he likes how squishy they are and continues to play with it long after the squeaker dies. Highly recommend and will be buying more

Great fetch toy.
Size: Medium, Style: Squeaker
My dog loves these balls. They are a bit softer than the normal ones and bounce well. The squeaker is not too loud but definitely makes the ball more interesting. I highly recommend these.

Good for small breeds and fun!
Color: Multi Squeaker Balls, Size: X-Small, Style: 4-Pack
I’m glad I found these for my 6 month puppies they absolutely love them super fun to play with. Although, the surface has come off due to my puppies biting it off. Look at the sizes as they have a few!
