Histone locus regulation by the Drosophila dosage compensation adaptor protein CLAMP.

The conserved histone locus body (HLB) assembles prior to zygotic gene activation early during development and concentrates factors into a nuclear domain of coordinated histone gene regulation. Although HLBs form specifically at replication-dependent histone loci, the cis and trans factors that target HLB components to histone genes remained unknown. Here we report that conserved GA repeat cis elements within the bidirectional histone3-histone4 promoter direct HLB formation in Drosophila In addition, the CLAMP (chromatin-linked adaptor for male-specific lethal [MSL] proteins) zinc finger protein binds these GA repeat motifs, increases chromatin accessibility, enhances histone gene transcription, and promotes HLB formation. We demonstrated previously that CLAMP also promotes the formation of another domain of coordinated gene regulation: the dosage-compensated male X chromosome. Therefore, CLAMP binding to GA repeat motifs promotes the formation of two distinct domains of coordinated gene activation located at different places in the genome.

Greater fertility distress and avoidance relate to poorer decision making about family building after cancer among adolescent and young adult female survivors.

BACKGROUND: Many adolescent and young adult female (AYA-F) cancer survivors face decisions about family building using reproductive medicine or adoption to achieve parenthood. This study evaluated associations among reproductive distress, avoidance, and family-building decision making and identified sociodemographic and clinical characteristics related to high distress and avoidance. METHODS: A cross-sectional survey assessed AYA-F survivors' oncofertility experiences. Measures included an investigator-designed Unmet Information Needs scale, Reproductive Concerns After Cancer Scale, Impact of Events Scale-Avoidance subscale, Decision Self-Efficacy scale, and Decision Conflict Scale. Two linear regression models evaluated correlates of decision self-efficacy and decisional conflict about family building after cancer. Bivariate analyses evaluated correlates of avoidance using Pearson's correlation, t-test, and ANOVA. RESULTS: AYA-Fs (N = 111) averaged 31-years-old (SD = 5.49) and 3 years post-treatment (range: 1-23 years); 90% were nulliparous. Most common diagnoses were leukemia (24%) and breast cancer (22%). Average decisional conflict was 52.12 (SD = 23.87, range: 0-100); 74% of the sample reported DCS scores within the clinically significant range. Higher levels of reproductive distress (B = -0.23, p = 0.04) and avoidance (B = -0.24, p = 0.02) related to lower decision self-efficacy. Younger age (B = -0.18, p = 0.03), greater unmet information needs (B = 0.33, p < 0.001), and higher levels of reproductive distress (B = 0.34, p = 0.001) related to worse decisional conflict. Predictors of distress and avoidance were identified. CONCLUSIONS: After cancer treatment, high fertility distress and avoidant coping were associated with poorer quality decision making about family building after cancer. Fertility counseling post-treatment should support self-efficacy and constructive coping skills to counteract high distress, maladaptive coping, and facilitate values-based decision making.

Perceptions of Infertility and Reproductive Concerns in Adolescent and Young Adult Female Cancer Survivors.

This cross-sectional survey study explores the fertility perceptions of adolescent and young adult female cancer survivors (n = 111) and relationships to fertility counseling and reproductive distress. Satisfaction with post-treatment fertility counseling (ß = -0.20, p = 0.04), perceived consequences of cancer-related fertility changes (ß = 0.26, p = 0.03), and understanding of one's reproductive health (ß = -0.22, p = 0.03) correlated with reproductive distress, controlling for covariates (F(10, 88) = 3.50, p < 0.001). Findings suggest that post-treatment counseling may be important to addressing survivors' perceptions of fertility and reproductive potential, which influences levels of distress and to create a greater sense of control on their road to parenthood.

Association of illness mindsets with health-related quality of life in cancer survivors.

OBJECTIVE: This study aimed to examine the association between mindsets-established, but mutable beliefs that a person holds-and health-related quality of life in survivors of breast and gynecologic cancer. METHOD: A cross-sectional survey study was conducted with breast and gynecologic cancer survivors. Measures included the Illness Mindset Questionnaire and Functional Assessment of Cancer Therapy-General (FACT-G). RESULTS: Two hundred seventy-three survivors (74% breast/26% gynecologic) who were on average 3.9 years post-diagnosis (SD = 4.2), Mage 55 (SD = 12) completed the survey (response rate 80%). Of the survivors, 20.1% (N = 55) endorsed ("agree" or "strongly agree") that Cancer is a Catastrophe, 52.4% (N = 143) endorsed that Cancer is Manageable, and 65.9% (N = 180) endorsed that Cancer can be an Opportunity (not mutually exclusive). Those who endorsed a maladaptive mindset (Cancer is a Catastrophe) reported lower health-related quality of life (HRQOL) compared with those who did not hold this belief (p < .001). Alternatively, those who endorsed more adaptive mindsets (Cancer is Manageable or Cancer can be an Opportunity) reported better HRQOL compared with those who disagreed (all p-values < .05). All three mindsets were independent correlates of HRQOL, explaining 6-15% unique variance in HRQOL, even after accounting for demographic and medical factors. CONCLUSIONS: Mindsets about illness are significantly associated with HRQOL in cancer survivors. Our data come from a one-time evaluation of cancer survivors at a single clinic and provide a foundation for future longitudinal studies and RCTs on the relationship between mindsets and psychosocial outcomes in cancer survivors.
