Trio of Drugs May Combat 'Triple Negative' Breast Cancer

In the new study, Johns Hopkins scientists began with a drug called Entinostat, which blocks an enzyme that unfolds DNA, providing regulatory molecules access to genes within and also reactivates a gene called retinoic acid receptor-beta (RARβ). Then, they added a drug called All Trans Retinoic Acid (ATRA), related to Vitamin A, which binds a protein made by the reactivated RARβ gene. Together, the ATRA drug and RARβ gene act as a brake on cancer cell growth.

Sporadic Breast Cancers Start With Ineffective DNA Repair Systems

Ultraviolet light, for example, can cause mutations, but a sophisticated system of nucleotide excision repair (NER) proteins trolls the DNA strands to identify problems and initiate repair processes. The same system repairs damage caused by many environmental carcinogens, including tobacco smoke.


"Even in healthy breast tissue, this system is only about one-fifth as effective as it is in skin,"

Potential New Target for Treating Triple Negative Breast Cancer Identified

Now researchers in Dublin (Ireland) have found that TNBC cells respond to compounds that disrupt the signalling processes of another receptor, EGFR (epidermal growth factor receptor), high levels of which are expressed in TNBC

Cured of TNBC!
I want to take this time out as a cancer survivor to encourage women out there still suffering from this with my story on how i got a cure. The sad news about it is that i was diagnosed on my 36th birthday in 2008 and with stage 3 TNBC which after i made research was a very aggressive form of cancer at that point i decided and told myself i was going to die and that the end has finally come. All my life i never thought of having breast cancer because i was very active and i worked out at the gym several times every week and my diet was okay. In my search for a cure after 6 years of diagnosis and even after chemo which i did twice spending thousands of dollars but to no avail, until a church member told me all about Dr Aleta a herbal doctor that specializes in treating TNBC, who could help me with a permanent cure, i doubted this at first but i later gave it a try following her methods and instructions. It took 3 months and after it all i felt normal but still went for diagnosis and i was clean today i am proud to say i am a cancer survivor no nodes and i am totally free the new diagnosis confirmed it. Do not die in silence or ignorance reach her on aletedwin@gmail.com don't be shy just speak to her today.
