Abstract: Cancer and neurodegenerative diseases are two of the leading causes of premature death in modern societies. Their incidence continues to increase, and in the near future, it is believed that cancer will kill more than 20 million people per year, and neurodegenerative diseases, due to the aging of the world population, will double their prevalence. The onset and the progression of both diseases are defined by dysregulation of the same molecular signaling pathways. However, whereas in cancer, these alterations lead to cell survival and proliferation, neurodegenerative diseases trigger cell death and apoptosis. The study of the mechanisms underlying these opposite final responses to the same molecular trigger is key to providing a better understanding of the diseases and finding more accurate treatments. Here, we review the ten most common signaling pathways altered in cancer and analyze them in the context of different neurodegenerative diseases such as Alzheimer’s (AD), Parkinson’s (PD), and Huntington’s (HD) diseases.

Cell cycle aberrations by α-synuclein over-expression and cyclin B immunoreactivity in Lewy bodies
Sang Seop Lee,Yong Man Kim,Eunsung Junn,Gwang Lee,K-H Park,Mikiei Tanaka,R D Ronchetti,Martha Quezado,M. Maral Mouradian +8 more
TL;DR: It is proposed that elevated expression of alpha-synuclein causes changes in cell cycle regulators through ERK activation leading to apoptosis of postmitotic neurons, also associated with ectopic expression of cyclin B in Lewy bodies.
Dopaminergic neuron‐specific deletion of p53 gene is neuroprotective in an experimental Parkinson's disease model
Xin Qi,Brandon Davis,Yung Hsiao Chiang,Emily Filichia,Austin Barnett,Nigel H. Greig,Barry J. Hoffer,Yu Luo +7 more
TL;DR: The results further support the role of programmed cell death mediated by p53 in this animal model of PD and identify Bax, BAD and PUMA genes as downstream targets of p 53 in modulating DA neuronal death in the in vivo MPTP‐induced PD model.
Neurofibrillary tangles may interfere with Smad 2/3 signaling in neurons
Katy A Chalmers,Seth Love +1 more
TL;DR: It is suggested that neurofibrillary tangles sequester pSmad3, preventing its translocation into the nucleus and the induction of gene transcription, which may adversely affect survival of tangle-bearing neurons in AD.
TGF-β Switches from Tumor Suppressor to Prometastatic Factor in a Model of Breast Cancer Progression
BW Tang,M Vu,T Booker,SJ Santner,FR Miller,MR Anver,LM Wakefield +6 more
TL;DR: This study investigates TGF-β's role in breast cancer progression, showing it switches from tumor suppressor to prometastatic factor, promoting metastasis in advanced disease, while cooperating with oncogenic lesions to initiate tumorigenesis in premalignant cells.
