Dear Yara Ahmed Mohamed

Yes, I am afraid that the journal “Epigenetics Research: Open Access” https://www.longdom.org/epigenetics-research-open-access.html is a predatory journal. The red flags are:

-The publisher behind it “Longdom Publishing SL” is identified as such, see for example here on RG https://www.researchgate.net/post/Longdom_Publication_Issue-Is_that_a_Predatory_Publication (see the replies of Wolfgang R. Dick and myself for what you might try once you want to withdraw a paper or submitted manuscript)

-The ‘papers’ published the last couple of years all seem fake (AI generated) short summaries of most likely real publications (most of them without a list of references). This publisher is notorious for this, see for example https://retractionwatch.com/2021/06/23/an-exercise-in-frustration-a-researcher-is-impersonated/

-After all those years the only indexing is Google Scholar https://www.longdom.org/epigenetics-research-open-access/indexing.html and for the papers I checked none of them (last couple of years) are indexed there (so even this is not true)

Once published you could try the suggestions as given above. But if it is still in the submission stage and you have not paid anything you should inform them that you request them to withdraw your submission and indicate that you never will pay anything (this might help them to conclude that they will not ‘earn’ anything when proceeding with your submission and ‘give up’).

Best regards.
