"What" in title

Is that the entire title, NL888?  Though it's already quite long, there seems to be something missing.

Typo: tess - tell

 
      Yes, your presuming is correct. The title is a translation.

      According the Chinese title, which I now translate into English as below (for being better understood, the translation looks quite loose as a title):
       The Effect of Cathepsin D in Type Ⅱ Cell Death of JM Cells Induced by Matrine and the Expression of Cathepsin D in Germinal Centers of Follicular Lymphoma and Follicular Hyperplasia

    That is why I ask if "What = the Expression of Cathepsin D."
     Does anyone think using "what" instead of "the Expression of Cathepsin D" is proper? 

  For the purpose of letting you better understand the title, I quote the abstract of the paper as following:

  The Expression of Cathepsin D in Type Ⅱ Cell Death of JM Cells Induced by Matrine and What in Germinal Centers of Follicular Lymphoma and Follicular Hyperplasia

  [Abstract] Leukemia is one of the severe diseases which endanger the health of the human being. The incidence of the disease is about 3-4/100,000 in China. Especially T lymphoblast leukemia, with its acute attack, high malignity, high recurrence, and poor prognosis, badly imperils the lives of children. To induce of PCD of tumor cells is an important strategy in neoplasma therapy. Because of lower side effect and obvious curative effect, some extracts from traditional Chinese herb have been put to the front in new...

 [Key words] matrine; JM cell; apoptosis; proliferation; follicular lymphoma; follicular hyperplasia;

Diving in here - if the translator thought for some reason that he or she could replace "The Expression of Cathepsin D" with "what" the second time it appears in the title, the translator was wrong. You could possibly leave it out the second time, maybe if you stuck in a "both." (That's if I'm parsing all these scientific terms correctly.)

"The Expression of Cathepsin D Both in Type II Cell Death of JM Cells Induced by Matrine and in Germinal Centers of Follicular Lymphoma and Follicular Hyperplasia"

And with maybe a little judicious use of Our Friend, the Comma. Not that we really need commas here - in fact I think they're technically incorrect - but sometimes they do help in this kind of long, dense chain.

"The Expression of Cathepsin D, Both in Type II Cell Death of JM Cells Induced by Matrine, and in Germinal Centers of Follicular Lymphoma and Follicular Hyperplasia"
