JNK inhibitor treatment also rescued myofiber degeneration and reduced the muscle expression of Trim63 and Fbxo32. These data demonstrate that JNK signaling contributes to muscle wasting in cancer cachexia, and its inhibition has the potential to be utilized as an anti-cachectic therapy.The inhibition of bromo- and extraterminal domains (BET) has shown an anti-proliferative effect in triple negative breast cancer (TNBC). In this article we explore mechanisms of resistance to BET inhibitors (BETi) in TNBC, with the aim of identifying novel ways to overcome such resistance. Two cellular models of acquired resistance to the BET inhibitor JQ1 were generated using a pulsed treatment strategy. MTT, colony formation, and cytometry assays revealed that BETi-resistant cells were particularly sensitive to PLK1 inhibition. Targeting of the latter reduced cell proliferation, especially in resistant cultures. Menin-MLL Inhibitor Quantitative PCR analysis of a panel of mitotic kinases uncovered an increased expression of AURKA, TTK, and PLK1, confirmed by Western blot. Only pharmacological inhibition of PLK1 showed anti-proliferative activity on resistant cells, provoking G2/M arrest, increasing expression levels of cyclin B, pH3 and phosphorylation of Bcl-2 proteins, changes that were accompanied by induction of caspase-dependent apoptosis. JQ1-resistant cells orthotopically xenografted into the mammary fat pad of mice led to tumours that retained JQ1-resistance. Administration of the PLK1 inhibitor volasertib resulted in tumour regression. These findings open avenues to explore the future use of PLK1 inhibitors in the clinical setting of BETi-resistant patients.The coordinated differentiation of hematopoietic stem and progenitor cells (HSPCs) into the various mature blood cell types is responsible for sustaining blood and immune system homeostasis. The cell fate decisions underlying this important biological process are made at the level of single cells. Methods to trace the fate of single cells are therefore essential for understanding hematopoietic system activity in health and disease and have had a major impact on how we understand and represent hematopoiesis. Here, we discuss the basic methodologies and technical considerations for three important clonal assays single-cell transplantation, lentiviral barcoding, and Sleeping Beauty barcoding. This perspective is a synthesis of presentations and discussions from the 2019 International Society for Experimental Hematology (ISEH) Annual Meeting New Investigator Technology Session and the 2019 ISEH Winter Webinar.The extra-embryonic hypoblast/visceral endoderm of Placentalia carries out a variety of functions during gestation, including hematopoietic induction. Results of decades-old and recent experiments have provided compelling evidence that, in addition to its inducing properties, hypoblast/visceral endoderm itself is a source of placental blood cells. Those observations that highlight extra-embryonic endoderm's role as an overlooked source of placental blood cells across species are briefly discussed here, with suggestions for future exploration.
To investigate whether predictions of retinal nerve fiber layer (RNFL) thickness obtained from a deep learning model applied to fundus photographs can detect progressive glaucomatous changes over time.

Retrospective cohort study.

Eighty-six thousand one hundred twenty-three pairs of color fundus photographs and spectral-domain (SD) OCT images collected during 21 232 visits from 8831 eyes of 5529 patients with glaucoma or glaucoma suspects.

A deep learning convolutional neural network was trained to assess fundus photographs and to predict SD OCT global RNFL thickness measurements. The model then was tested on an independent sample of eyes that had longitudinal follow-up with both fundus photography and SD OCT. The ability to detect eyes that had statistically significant slopes of SD OCT change was assessed by receiver operating characteristic (ROC) curves. The repeatability of RNFL thickness predictions was investigated by measurements obtained from multiple photographs that had been acquired during nt of variation of 3.2% (95% CI, 3.1%-3.3%).

A deep learning model was able to obtain objective and quantitative estimates of RNFL thickness that correlated well with SD OCT measurements and potentially could be used to monitor for glaucomatous changes over time.

To compare the prevalence of intravitreal silicone oil microdroplets detected by slit-lamp biomicroscopy in eyes with 6 or more injections of the same anti-vascular endothelial growth factor (VEGF) drug.

Prospective, cross-sectional case series.

A total of 260 consecutive eyes receiving 1 of 3 intravitreal anti-VEGF drugs for choroidal neovascularization, diabetic macular edema, or venous occlusive disease. The control group included 147 fellow eyes with no prior intravitreal injections.

The anterior and mid-vitreous were carefully examined using 12× to 16× magnification through dilated pupils with ocular saccades before an injection. Silicone oil microdroplets were graded on a scale from 0 to 4+ based on the number and size of droplets.

Presence and severity of silicone oil microdroplets in the vitreous.

Silicone oil microdroplets were observed in 78.3% of eyes receiving bevacizumab in Becton Dickinson (BD, Franklin Lakes, NJ) 0.3-mL polypropylene syringes, 14.4% of eyes receiving ranibizumab in yes receiving multiple regular anti-VEGF injections should be supplied in silicone-free syringes.
The BD 0.3-mL polypropylene syringes with repackaged bevacizumab and the BD 1.0-mL polycarbonate syringes with aflibercept cause a higher likelihood of silicone oil microdroplets. Intravitreal injections in eyes receiving multiple regular anti-VEGF injections should be supplied in silicone-free syringes.
To quantify and evaluate patients with diabetic retinopathy (DR) who had at least a 4-step improvement on the Early Treatment Diabetic Retinopathy Study (ETDRS) Diabetic Retinopathy Severity Scale (DRSS) in response to treatment with ranibizumab in the Diabetic Retinopathy Clinical Research Network (DRCR.net) Protocol S study, and factors predictive of such improvements.

Post hoc retrospective analysis of 2-year outcomes in the phase 3 Protocol S study.

Patients randomized to treatment with ranibizumab 0.5 mg with sufficient baseline DRSS severity (≥47) to allow for an at least 4-step improvement (n= 181).

Study eyes received a ranibizumab 0.5 mg injection at baseline and every 4 weeks for 12 weeks, with subsequent as-needed injections. Fundus photographs graded at baseline and years 1 and 2 using DRSS were used for this analysis. The data source is DRCR.net, but analyses, content, and conclusions of this report are solely the responsibility of the authors.

Proportion of eyes achieving at least a 4-step DRSS improvement (DR ultra-response) at years 1 and 2; treatment course for eyes achieving ultra-response; mean change in best-corrected visual acuity (BCVA) in eyes with and without ultra-response; factors associated with ultra-response (identified by univariate and multivariable analyses).
