Something like this:

(defun gnus-user-format-function-y (ignore)
  (if gnus-newsgroup-name
      (with-temp-buffer
	(gnus-request-article-this-buffer number gnus-newsgroup-name)
	(gnus-narrow-to-body)
	(if (re-search-forward "From \\(.*\\)$" nil t)
	    (match-string 1)
	  ""))
    ""))

It'll slow down summary buffer generation a lot, of course.

It's probably easier to use scoring (where you can score on the body)
for something like this.
