Interleukin-27 is a pleiotropic cytokine whose functions during bacterial infections remain controversial, and its role in patients with S. aureus osteomyelitis is unknown. To address this knowledge gap, we completed a clinical study and observed elevated serum IL-27 levels (20-fold higher, P < 0.05) in patients compared with healthy controls. Remarkably, IL-27 serum levels were 60-fold higher in patients immediately following septic death than in uninfected patients (P < 0.05), suggesting a pathogenic role of IL-27. To test this hypothesis, we evaluated S. aureus osteomyelitis in WT and IL-27Rα Show less
In the neoadjuvant WSG-ADAPT-TN trial, 12-week nab-paclitaxel + carboplatin (nab-pac/carbo) was highly effective and superior to nab-paclitaxel + gemcitabine (nab-pac/gem) in triple-negative breast ca Show more
In the neoadjuvant WSG-ADAPT-TN trial, 12-week nab-paclitaxel + carboplatin (nab-pac/carbo) was highly effective and superior to nab-paclitaxel + gemcitabine (nab-pac/gem) in triple-negative breast cancer regarding pathological complete response (pCR). Predictive markers for deescalated taxane/carbo use in TNBC need to be identified. Patients received 4 × nab-pac 125 mg/m Show less

We performed whole exome sequence (WES) to identify genetic modifiers on 184 individuals with 22q11.2 deletion syndrome (22q11DS), of whom 89 case subjects had severe congenital heart disease (CHD) and 95 control subjects had normal hearts. Three genes including JMJD1C (jumonji domain containing 1C), RREB1 (Ras responsive element binding protein 1), and SEC24C (SEC24 family member C) had rare (MAF < 0.001) predicted deleterious single-nucleotide variations (rdSNVs) in seven case subjects and no control subjects (p = 0.005; Fisher exact and permutation tests). Because JMJD1C and RREB1 are involved in chromatin modification, we investigated other histone modification genes. Eighteen case subjects (20%) had rdSNVs in four genes (JMJD1C, RREB1, MINA, KDM7A) all involved in demethylation of histones (H3K9, H3K27). Overall, rdSNVs were enriched in histone modifier genes that activate transcription (Fisher exact p = 0.0004, permutations, p = 0.0003, OR = 5.16); however, rdSNVs in control subjects were not enriched. This implicates histone modification genes as influencing risk for CHD in presence of the deletion. Show less
