The addition has seen the names on the petition more than double to more than 13,000 since July, with numbers still rising.
Organiser Maggie Watts said:
"Coronation Street just embarked on a pancreatic cancer story-line with Julie's character Hayley.
"Julie has completely embraced the e-petition and is promoting it on Twitter and in the media wherever she can.
"Her input has made a significant difference to raising the profile of the e-petition and pancreatic cancer in general.
"We will now receive a response from the government because we hit the 10,000-name petition.
"We are awaiting that response which will give us an update on where the government stands on the issues raised".
Maggie, whose husband Kevin died in 2009 aged just 49, said:
"The survival rate for sufferers has not improved in the past 40 years.
"Pancreatic cancer is the fifth leading cause of UK cancer death with the worst survival rate of all cancers, yet it receives only one per cent of the budget for research.
"We want the government to provide more funding and awareness".
In an interview with a national newspaper, actress Julie said:
"There's an amazing woman called Maggie Watts who lost her husband to pancreatic cancer.
"She started this e-petition. To get it to Downing Street you have to get 10,000 people to sign it, and to get a debate on it, you need 100,000 signatures.
"I've put it all over my Twitter and I am trying to get as many people backing it as possible.
"It's really bad, there's no research funding and no improvement in survival rates."
