Importance of PLD2 in an IL-23 driven psoriasiform dermatitis model and potential link to human psoriasis.

Phospholipase D2 (PLD2), a major isoform of the PLD family, has been reported to regulate inflammatory responses. Thus far, the relevance of PLD2 in psoriasis, an inflammatory skin disease, has not been explored. In the current study, we examined PLD2 expression in the skin of psoriasis patients and the role of PLD2 in an interleukin (IL)-23-induced mouse model of psoriasiform dermatitis.

Polygenic risk modeling for prediction of epithelial ovarian cancer risk.

Polygenic risk scores (PRS) for epithelial ovarian cancer (EOC) have the potential to improve risk stratification. Joint estimation of Single Nucleotide Polymorphism (SNP) effects in models could improve predictive performance over standard approaches of PRS construction. Here, we implemented computationally efficient, penalized, logistic regression models (lasso, elastic net, stepwise) to individual level genotype data and a Bayesian framework with continuous shrinkage, "select and shrink for summary statistics" (S4), to summary level data for epithelial non-mucinous ovarian cancer risk prediction.

Uptake and timing of bilateral and contralateral risk-reducing mastectomy in women with Li-Fraumeni syndrome.

Purpose: Women with Li-Fraumeni Syndrome (LFS) often consider risk-reducing mastectomy (RRM) due to extremely high risk of breast cancer at early ages. Data on uptake of RRM in LFS are scarce, and are inferred from experience in women with pathogenic variants (PVs) in BRCA1/2, despite differences in cancer risks. This study evaluated RRM uptake in a cohort of women with LFS.

Family Identity and Roles in the Context of Li-Fraumeni Syndrome: "No One's Like Us Mutants".

Li-Fraumeni syndrome (LFS) is a rare hereditary cancer syndrome in which individuals have a significantly increased risk of developing multiple cancers throughout the life span. An LFS diagnosis may shift the individual's sense of self and tolerance of cancer risk as they engage in cancer screening and cancer prevention activities. This study examined the impact of family identity on health decision making, communication, and role function.
