Project description:Gene expression was studied from the blood derived RNAs of the Finnish family members as well as from 10 controls using GeneChip Human Genome U133 Plus2 (Affymetrix). Eight out of 10 family members in the expression analysis are heterozygous for the NPAT c.2437-2438delAG, three of which are NLPHL cases.

Eight out of 10 family members in the expression analysis are heterozygous for the NPAT c.2437-2438delAG, three of which are NLPHL cases. NPAT expression was studied in the NLPHL patients and the carriers of the deletion c.2437-2438delAG (8) compared to the controls and the non-mutation carriers (12). Note: Case 2 not submitted. Publication pending.
Project description:Objectives:
Specific Aims:
1. Researchers will evaluate and compare predictors of health-related quality of life (QOL) among colorectal cancer (CRC) survivors who have Lynch syndrome (LS) with those patients who have sporadic CRC using both quantitative and qualitative methodology.
a. In both CRC groups, researchers will evaluate cancer preventive and health behaviors, including lifestyle factors and screening, psychosocial factors, including mood, family functioning, coping style, anxiety, depression, and social resources, and health care system factors, including interactions with health care providers and service utilization.
2. Researchers will compare the experience of first-degree relatives (FDRs) of patients who have LS with that of FDRs of patients who have sporadic CRC using both quantitative and qualitative methodology.
a. Researchers will evaluate all of the domains listed above, as well as anticipatory grief, assessment of caregiving responsibilities, and fear of cancer in FDRs of patients with LS-related and sporadic CRC.
3. Researchers will examine CRC patients from both groups and their FDRs using dyadic analyses in order to evaluate the similarities and differences in their survivorship experience.
4. Researchers will evaluate the preventive and health behavior of patients who are non-conclusive for Lynch syndrome and their family members. They will examine their screening behavior and will explore how the interaction between the patients and their relatives affects the relatives’ screening behavior. They also will examine how these non conclusive LS patients and their family members perceive their risk for LS-related cancers.
Project description:In animals, microRNAs frequently form families with related sequences. The functional relevance of miRNA families and the relative contribution of family members to target repression have remained, however, largely unexplored. Here, we used the C. elegans miR-58 miRNA family, comprised primarily of four highly abundant members: miR-58.1, miR-80, miR-81 and miR-82, as a model to investigate the redundancy of miRNA family members and their impact on target expression in an in vivo setting.
