Life stage impact on the human skin ecosystem: lipids and the microbial community.

Sebaceous free fatty acids are metabolized by multiple skin microbes into bioactive lipid mediators termed oxylipins. This study investigated correlations between skin oxylipins and microbes on the superficial skin of pre-pubescent children (N = 36) and adults (N = 100), including pre- (N = 25) and post-menopausal females (N = 25). Lipidomics and metagenomics revealed that Malassezia restricta positively correlated with the oxylipin 9,10-DiHOME on adult skin and negatively correlated with its precursor, 9,10-EpOME, on pre-pubescent skin.

DNTT-mediated DNA Damage Response Drives Inotuzumab Ozogamicin Resistance in B-cell Acute Lymphoblastic Leukemia.

Inotuzumab Ozogamicin (InO) is an antibody-calicheamicin conjugate with striking efficacy in B-cell acute lymphoblastic leukemia (B-ALL). However, there is wide inter-patient variability in treatment response, and the genetic basis of this variation remains largely unknown. Using a genome-wide CRISPR screen, we discovered the loss of DNTT as a primary driver of InO resistance.

Repeated social stress increases posterior medial amygdala neuronal activity in stress-susceptible adult male rats.

The medial amygdala (MeA) is activated by social stimuli and manipulations of the MeA disrupt a wide range of social behaviors. Social stress can shift social behaviors and may accomplish this partly via effects on the MeA. However, very little is known about the effects of social stress on the electrophysiological activity of MeA neurons.

The Proteomics of T-Cell and Early T-Cell Precursor (ETP) Acute Lymphocytic Leukemia: Prognostic Patterns in Adult and Pediatric-ETP ALL.

Background: The 5-year overall survival (OS) rates of T-cell lymphocytic leukemia (T-ALL) are better for children (>90%) compared to adults (~57%). The early T-cell precursor (ETP) T-ALL subtype is prognostically unfavorable in adults, but less significant in pediatric T-ALL, and the diagnosis and prognosis of "near"-ETP is controversial. We compared protein and RNA expression patterns in pediatric and adult T-ALL to identify prognostic subgroups, and to further characterize ETP and near-ETP T-ALL in both age groups.
