PUBLICATIONS(Ranked by impact factor of the journal)Researchers concluded that TUDOR domain–containing PHF20L1 as a H3K27me2 reader exerted transcriptional repression by recruiting polycomb repressive complex 2 PRC2) and Mi-2/nucleosome remodeling and deacetylase(NuRD) complex, linking PRC2-mediated methylation and NuRD-mediated deacetylation of H3K27. [Sci Adv] Full Article Cdk4 and Cdk6 Couple the Cell-Cycle Machinery to Cell Growth via mTORC1 Scientists showed that CyclinD-Cdk4/6 activated mTORC1 by binding and phosphorylating TSC2 on Ser1217 and Ser1452. [Cell Rep] Full Article | Graphical Abstract Researchers found regulatory state heterogeneity was jointly coordinated by the NRF2 and p53 pathways, which were costabilized by spontaneous oxidative stress within 3D cultures. [Sci Signal] Full Article Crosstalk between Hydroxytyrosol, a Major Olive Oil Phenol, and HIF-1 in MCF-7 Breast Cancer Cells Investigation into MCF-7 breast cancer cells indicated that hydroxytyrosol decreased hypoxia inducible factor-1α protein, probably by downregulating oxidative stress and by inhibiting the PI3K/Akt/mTOR pathway. [Sci Rep] Full Article CDDO-Me Alters the Tumor Microenvironment in Estrogen Receptor Negative Breast Cancer Scientists showed that CDDO-methyl ester remodels the breast tumor microenvironment, redirecting tumor associated microphages activation and T cell tumor infiltration in vivo.” [Sci Rep] Full Article The authors ablated the expression of keratin 19(K19) in breast cancer cells of the MDA-MB-231 cell line and found that cells lacking K19 became more elongated in culture, with morphological reversion toward the parental phenotype upon transduction of KRT19. [Cytometry A] Abstract Astrocytic IGFBP2 and CHI3L1 in Cerebrospinal Fluid Drive Cortical Metastasis of HER2+Breast Cancer Investigators hypothesized that factors in cerebrospinal fluid play a critical role in the adaptation, proliferation, and establishment of cortical metastases. [Clin Exp Metastasis] Abstract Scientists report the potent cytotoxic effect of a series of repurposed flexible bis-imidamides 1–4, triaryl bis-guanidine 5 and bis-N-substituted guanidines 6,7 having a 1,4-diphenoxybenzene scaffold backbone on MCF-7 and MDA-MB-231 breast cancer cell lines.

INDUSTRY NEWSAntengene announced that it has dosed the first patient in Taiwan, China in its Phase I open-label clinical trial of ATG-019 (KPT-9274), a dual inhibitor of both p21-activated kinase 4 and nicotinamide phosphoribosyl transferase. [Antengene Corporation] Press Release Pattern Computer Receives Positive Pre-Clinical Test Results for Breast Cancer Drug Candidates Pattern Computer®, Inc. announced that two sets of drug therapy candidates targeting breast cancer – identified through its proprietary machine-learning pattern discovery system – completed final in vitro organoid testing from a leading national lab demonstrating “significant synergistic interaction” in killing malignant tumor growth, with statistically low to no adverse effects on healthy cell states.

POLICY NEWSThe head of the World Health Organization expressed “regret” that President Trump intends to cut off US funding to the agency over its handling of the coronavirus, but pointedly avoided criticizing the US move. [STAT News] Editorial Ending Coronavirus Lockdowns Will Be a Dangerous Process of Trial and Error After the novel coronavirus made its way from China around the world, one country after another adopted harsh measures to stop SARS-CoV-2 from spreading and overwhelming hospitals. They have hit the pause button on their economies and their citizens’ lives, stopping sports events, religious services, and other social gatherings. [ScienceInsider] Editorial
