It was well established that optimistic attitudes in cancer patients predict better psychological and physical adjustment to the illness both during and after the treatment (Mazanec, Daly, Douglas, & Lipson, 2010; Bozo, Gündoğdu, & Büyükaşık-Çolak, 2009). Previous studies indicated that optimism is indirectly associated with cancer patients' quality of life (QOL) through coping styles and appraisals used by the patients (Schou, Ekeberg, & Ruland, 2005). To understand whether there are other psychological mechanisms underlying the relation of optimism with quality of life and depressive symptoms of cancer patients, the current study aimed to investigate the mediator role of cancer related selfefficacy. One hundred and twenty cancer patients participated in the study and Life Orientations Test-Revised, Cancer Behavior Inventory, Beck Depression Inventory, and Multidimensional Quality of Life Scale–Cancer were administered to them. Results revealed that of the four self-efficacy domains, only the one related to maintaining activity and independence mediated the optimism-QOL and optimism-depression relations. These findings highlighted the importance of patients' beliefs in their ability to sustain their daily activities for having better physical and psychological well-being.

Optimistic attitudes of cancer patients are shown as an important personal resource for the psychological and physical adjustment to the illness. Coping styles and appraisals were suggested as indirect pathways through which optimism associates with better functioning in patients. The current study aimed to investigate the role of cancer-specific self-efficacy domains (i.e., coping with cancer-related side effects and stress, maintaining activity and independence, seeking and understanding medical informati...
Alternative Polyadenylation patterns for novel gene discovery and classification in cancer
Beğik, Oğuzhan; Öyken, Merve; Can, Tolga; Erson Bensan, Ayşe Elif (2017-06-03)
Certain aspects of diagnosis, prognosis and treatment of cancer patients are still important challenges to be addressed. Therefore, we propose a pipeline to uncover patterns of alternative polyadenylation (APA), a hidden complexity in cancer transcriptomes, to further accelerate efforts to discover novel cancer genes and pathways. Here, we analyzed expression data for 1,045 cancer patients and found a significant shift in usage of poly(A) signals in cancers. Using machine-learning techniques, we further def...

Therefore, we propose a pipeline to uncover patterns of alternative polyadenylation (APA), a hidden complexity in cancer transcriptomes, to further accelerate efforts to discover novel cancer genes and pathways. Here, we analyzed expression data for 1045 cancer patients and found a significant shift in usage of poly(A) signals in common tumor types (breast, colon, lung, prostate, gastric...

Certain aspects of diagnosis, prognosis, and treatment of cancer patients are still important challenges to be addressed. We developed a pipeline to uncover patterns of alternative polyadenylation (APA), a hidden complexity in cancer transcriptomes, to further accelerate efforts to discover novel cancer genes and pathways. Here, we found a significant shift in usage of poly(A) signals in six common tumor types compared to normal tissues. We further defined specific subsets of APA events to efficiently class...
