How to make the “Like this” text all-caps

Hello. I’m trying to make the header text of social sharing, like, and related posts uniform. There is an option to type the header for social sharing and related posts as you want it to appear, but none for likes. So this it how it is now:

SHARE THIS ON:
Like this:
RELATED POSTS:

I want the Like this: to be all-caps as well. Thanks.
