A new biologically inspired “injectable cryogel whole-cell cancer vaccine” combines patient-specific harvested cancer cells and immune-stimulating chemicals or biological molecules to help the body attack cancer. It has been developed by scientists at Harvard’s Wyss Institute and Dana-Farber Cancer Institute.

This new approach is simpler and more economical than other cancer cell transplantation therapies, which harvest tumor cells and then genetically engineer them to trigger immune responses once they are transplanted back into the patient’s body, the researchers say.

““To some extent, social media platforms can promote democratic deliberation and the exchange of ideas from different perspectives,” says Barberá. “Even for the most divisive topics, such as the 2012 presidential election, we did not see a perfect division on Twitter — while people may encounter political views that they agree with, they’ll encounter divergent opinions as well.””

An interesting paper that uses ALA to shore up telomerase activity, loss of telomeres inhibition of P53 expression and mitochondrial dysfunction in one go. They use ALA (alpha lipoic acid) to induce PGC-1α in this case though PGC1-alpha seems to be a potential target for intervention as I understand that ALA is difficult to deliver to cells. In this case this involves the vascular system and atherosclerosis.

Short telomeres and Mitochondrial dysfunction are increasingly implicated as being closely linked as this 2012 Dephino paper demonstrates in the aging heart:

LISTENING, the award-winning debut feature from visionary director Khalil Sullins, is a psychological thriller about penniless grad students who invent mind-reading technology that destroys their lives. David, Ryan, and Jordan hope the telepathy invention will solve all their problems, but the bleeding-edge technology opens a Pandora’s box of new dangers, as the team discovers that when they open their minds, there is nowhere to hide their thoughts. Secrets and betrayals surface, and the technology is stolen by a covert government agency with a hidden agenda. With no one left to trust, David is forced against his friends in a life-or-death battle over not only the privacy of the human mind, but the future of free will itself.

Most cancer-busting strategies focus on removing cancerous cells. While this approach has proved extremely effective on many patients, most treatments have unpleasant side effects and there are many strains which prove extremely challenging to remove. An alternative model to this is to alter instead of remove — fixing cancerous behaviour by ‘reprogramming’ cells that go rogue; essentially swiss finishing school for cellular miscreants. A study published in Nature Cell Biology now provides hope that this tactic could in fact work in many cancers.

Researchers from Mayo Clinic’s Florida campus have found that adhesion proteins, which act like a glue sticking cells together, actually interact with a cell’s ‘microprocessor’. This processor creates molecules called miRNAs, which regulate multiple genes and essentially activate or de-activate different behavioural programs (like commands in computer programming). When healthy cells bump into a neighbour and begin to glue together, these adhesion proteins normally influence both cells — tuning down growth pathways. In cancer, the lab found this adhesion is perturbed; de-regulating miRNA production and enabling rampant growth. When scientists corrected these miRNA levels, the growth was arrested.
