From Gaslighting to Enlightening: Reproductive Justice as an Interdisciplinary Solution to Close the Health Gap.

This conceptual article aims to inform social work educators on facilitating critical discourse among social work students by applying reproductive justice, leveraging interdisciplinary practice, and addressing the Social Work Grand Challenges. Reproductive justice tenets provide an interdisciplinary framework that assists in the development of the learning environment, participant's critical thinking, self-awareness, and self-regulation; preparing them for professional dialog and ethical decision making. This article will outline the tenets of reproductive justice, providing resources and tools for creating an environment that will assist in the facilitation of critical and professional conversations; while providing strategies that incorporate interdisciplinary partners into the classroom thus providing a reproductive justice sensitive analysis and solutions for approaching social issues that affect the people social workers serve.

Small molecule targeting of the STAT5/6 Src homology 2 (SH2) domains to inhibit allergic airway disease.

Asthma is a chronic inflammatory disease of the lungs and airways and one of the most burdensome of all chronic maladies. Previous studies have established that expression of experimental and human asthma requires the IL-4/IL-13/IL-4 receptor α (IL-4Rα) signaling pathway, which activates the transcription factor STAT6. However, no small molecules targeting this important pathway are currently in clinical development.

Combinatorial effects of histone deacetylase inhibitors (HDACi), vorinostat and entinostat, and adaphostin are characterized by distinct redox alterations.

Purpose: Amongst the epigenetically targeted therapies, targeting of the histone deacetylases (HDACs) has yielded numerous drugs for clinical use in hematological malignancies, but none as yet for acute lymphocytic leukemia (ALL). Single agent activity of HDAC inhibitors (HDACi) has been elusive in ALL, and has prompted study of combinatorial strategies. Because several HDACi raise levels of intracellular oxidative stress, we evaluated combinations of two structurally distinct HDACi with the redox active compound adaphostin in ALL.

Transfer of Dyes and Drugs into Cells Using EGFR-Targeted Nanosyringes.

Selective targeting of drug loaded nanovectors to specific epitopes highly expressed on the surface of cancer cells is a goal for nanotechnologists. We have modified our previously described PEGylated-hydrophilic carbon clusters (PEG-HCCs) so that the epidermal growth factor receptor (EGFR) binding peptide, GE11, is attached using click chemistry at the end of each PEG. The resulting nanosyringe, Pep-PEG-HCC, can be loaded with a wide range of hydrophobic drugs and dyes.

Induction of cell death by the novel proteasome inhibitor marizomib in glioblastoma in vitro and in vivo.

New therapies for glioblastoma (GBM) are needed, as five-year survival is <10%. The proteasome inhibitor marizomib (MRZ) has inhibitory and death-inducing properties unique from previous inhibitors such as bortezomib (BTZ), and has not been well examined in GBM. We evaluated the mechanism of death and in vivo properties of MRZ in GBM.

Preclinical activity of combined HDAC and KDM1A inhibition in glioblastoma.

Background: Glioblastoma (GBM) is the most common and aggressive form of brain cancer. Our previous studies demonstrated that combined inhibition of HDAC and KDM1A increases apoptotic cell death in vitro. However, whether this combination also increases death of the glioma stem cell (GSC) population or has an effect in vivo is yet to be determined.

Expression and activity of Fyn mediate proliferation and blastic features of chronic myelogenous leukemia.

The BCR-ABL1 oncogene is a tyrosine kinase that activates many signaling pathways, resulting in the induction of chronic myeloid leukemia (CML). Kinase inhibitors, such as imatinib, have been developed for the treatment of CML; however, the terminal, blast crisis phase of the disease remains a clinical challenge. Blast crisis CML is difficult to treat due to resistance to tyrosine kinase inhibitors, increased genomic instability and acquired secondary mutations.

Inhibition of the NADPH oxidase regulates heme oxygenase 1 expression in chronic myeloid leukemia.

Background: Patients with chronic myelogenous leukemia (CML) in blast crisis have a poor response to tyrosine kinase inhibitors designed to inhibit the breakpoint cluster region-v-Abelson murine leukemia viral oncogene homolog 1 (BCR-ABL1) oncogene. Recent work has demonstrated that heme oxygenase 1 (HO-1) expression is increased in BCR-ABL1-expressing cells and that the inhibition of HO-1 in CML leads to reduced cellular growth, suggesting that HO-1 may be a plausible target for therapy. The objective of the current study was to clarify the mechanism of HO-1 overexpression and the role of the nicotinamide adenine dinucleotide phosphate (NADPH) oxidase as a contributor to this mechanism in CML.

Therapeutic strategies to enhance the anticancer efficacy of histone deacetylase inhibitors.

Histone acetylation is a posttranslational modification that plays a role in regulating gene expression. More recently, other nonhistone proteins have been identified to be acetylated which can regulate their function, stability, localization, or interaction with other molecules. Modulating acetylation with histone deacetylase inhibitors (HDACi) has been validated to have anticancer effects in preclinical and clinical cancer models.

Inhibition of LSD1 sensitizes glioblastoma cells to histone deacetylase inhibitors.

Glioblastoma multiforme (GBM) is a particularly aggressive brain tumor and remains a clinically devastating disease. Despite innovative therapies for the treatment of GBM, there has been no significant increase in patient survival over the past decade. Enzymes that control epigenetic alterations are of considerable interest as targets for cancer therapy because of their critical roles in cellular processes that lead to oncogenesis.

Role for the nuclear receptor-binding SET domain protein 1 (NSD1) methyltransferase in coordinating lysine 36 methylation at histone 3 with RNA polymerase II function.

The NSD (nuclear receptor-binding SET domain protein) family encodes methyltransferases that are important in multiple aspects of development and disease. Perturbations in NSD family members can lead to Sotos syndrome and Wolf-Hirschhorn syndrome as well as cancers such as acute myeloid leukemia. Previous studies have implicated NSD1 (KMT3B) in transcription and methylation of histone H3 at lysine 36 (H3-K36), but its molecular mechanism in these processes remains largely unknown.

Regulation of DNA repair through deSUMOylation and SUMOylation of replication protein A complex.

The replication protein A complex (RPA) plays a crucial role in DNA replication and damage response. However, it is not known whether this complex is regulated by the SUMOylation pathway. Here, we show that the 70 kDa subunit of RPA (RPA70) associates with a Sentrin/SUMO-specific protease, SENP6, in the nucleus to maintain RPA70 in a hypoSUMOylated state during S phase.

Maternal protein restriction leads to hyperresponsiveness to stress and salt-sensitive hypertension in male offspring.

Low birth weight humans often exhibit hypertension during adulthood. Studying the offspring of rat dams fed a maternal low-protein diet is one model frequently used to study the mechanisms of low birth weight-related hypertension. It remains unclear whether this model replicates key clinical findings of hypertension and increased blood pressure responsiveness to stress or high-salt diet.
