- Fission yeast centromeric repeats are transcribed into small interfering RNA (siRNA) precursors (pre-siRNAs), which are processed by Dicer to direct heterochromatin formation. Recently, Rpb1 and Rpb2 subunits of RNA polymerase II (RNA Pol II) were shown to mediate RNA interference (RNAi)-directed chromatin modification but did not affect pre-siRNA levels. Here we show that another Pol II subunit, Rpb7 has a specific role in presiRNA transcription. We define a centromeric presiRNA promoter from which initiation is exquisitely sensitive to the rpb7-G150D mutation. In contrast to other Pol II subunits, Rpb7 promotes pre-siRNA transcription required for RNAi-directed chromatin silencing.

- The aim of this study was to describe the dyspnea experience and examine its relation to other symptoms, personal and health-related factors and its predictors in patients with lung cancer. The subjects were 105 patients diagnosed with lung cancer, approached when active anti-tumour treatment was closed. The patients completed a battery of questionnaires about several aspects of dyspnea experience, intensity of other symptoms and coping capacity. Medical data including performance status were obtained from medical records. Above 50% of the patients perceived dyspnea. Coping capacity, performance status and other symptoms correlated with different aspects of dyspnea experience. Dyspnea dimensions and activity-related dyspnea correlated with anxiety, depression, fatigue and cough as well as negatively to coping capacity. Performance status correlated with dyspnea intensity and activity-related dyspnea. Lower coping capacity predicted dyspnea; additional predictors were higher levels of anxiety and fatigue. Dyspnea in this group of patients was a complex experience, including physical and psychological aspects and should preferably be assessed in a comprehensive way. A nursing intervention to decrease dyspnea experience and anxiety could use knowledge from this study about the importance of coping capacity to better help patients with lung cancer to cope in their palliative phase of the disease

- The aims of the study were to investigate lung cancer patients' quality of life (QoL) over time in a palliative setting and to determine how QoL is influenced by symptoms, coping capacity, and social support. One hundred and five consecutive patients with incurable lung cancer were included. A comprehensive set of questionnaires was used at baseline, including the Assessment of Quality of Life at the End of Life, Cancer Dyspnea Scale, Visual Analog Scale of Dyspnea, Hospital Anxiety and Depression scale, Sense of Coherence Questionnaire, and Social Support Survey, of which the first four were used also at three, six, nine, and 12 months. Dyspnea, depression, and global QoL deteriorated over time. Performance status, anxiety, depression, components of dyspnea, pain, and the meaningfulness component of coping capacity correlated with global QoL at all, or all but one follow-up measurements. In a multivariate analysis with global QoL as the dependent variable, depression was a significant predictor at four out of five assessments, whereas coping capacity, anxiety, performance status, pain, and social support entered the model at one or two assessments. Emotional distress and coping capacity influence QoL and might be targets for intervention in palliative care.
