Identification of an immune subtype predicting survival risk and immune activity in hepatocellular carcinoma.

Aging (Albany NY) 2021 May 3;13. Epub 2021 May 3.

Toxicology and Functional Laboratory, Shandong Center for Disease Control and Prevention, Jinan 250014, Shandong, China.

Immune checkpoint inhibitors (ICI) prolong the survival for advanced/metastatic patients with lung cancer or melanoma; however, for hepatocellular carcinoma (HCC) patients, a durable response has not been reported. Herein, we used a total of 719 HCC patients with public genomic data to determine potential prognostic and immunogenic subtypes. The non-negative matrix factorization (NMF) method was applied to identify the immune classes and potential subtypes. Read More

3D heterospecies spheroids of pancreatic stroma and cancer cells demonstrate key phenotypes of pancreatic ductal adenocarcinoma.

Transl Oncol 2021 May 1;14(7):101107. Epub 2021 May 1.

Pancreas Cancer Research Lab, Department of Clinical Science, Intervention and Technology, (CLINTEC), Karolinska Institutet, Huddinge SE 141 86, Sweden. Electronic address:

Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal malignancies, partly due to the dense desmoplasia and a lack of suitable model systems to study. In the present work, we developed a 3D heterospecies spheroid model to study the microenvironmental interactions between tumor cells and stellate cells which can also be employed to test therapeutic regimens. We set up monospheroids and heterospheroids made up from murine pancreatic stellate cells (mPSCs) and human PDAC cells (Panc1), which allowed for direct isolation of mRNA from a mixed cell population followed by an in silico separation of the RNA-seq reads.

Article Topic/Title: Primary cutaneous T-cell lymphomas other than Mycosis Fungoides and Sezary Syndrome. Part II: Prognosis and Management.

J Am Acad Dermatol 2021 May 1. Epub 2021 May 1.

Memorial Sloan Kettering Cancer Center, New York, NY. Electronic address:

Primary cutaneous T-cell lymphomas (CTCLs) other than Mycosis Fungoides (MF) and Sézary syndrome (SS) encompass a heterogenous group of non-Hodgkin lymphomas with variable clinical course, prognoses, and management. With morphologic and histologic overlap among the CTCL subtypes and other T-cell lymphomas with cutaneous manifestations, thorough evaluation with clinicopathologic correlation and exclusion of systemic involvement are essential prior to initiating therapy. Staging and treatment recommendations vary depending on the subtype, clinical behavior, and treatment response. Read More

Targeting epigenetic mechanisms to overcome venetoclax resistance.

Biochim Biophys Acta Mol Cell Res 2021 May 1:119047. Epub 2021 May 1.

University of Florida Health Cancer Center, and University of Florida, Department of Medicine, Division of Hematology and Oncology, Gainesville, FL 32610. Electronic address:

The BH-3 mimetic venetoclax overcomes apoptosis and therapy resistance caused by high expression of BCL2 or loss of BH3-only protein function. Although a promising therapy for hematologic malignancies, increased expression of anti-apoptotic MCL-1 or BCL-XL, as well as other resistance mechanisms prevent a durable response to venetoclax. Recent studies demonstrate that agents targeting epigenetic mechanisms such as DNA methyltransferase inhibitors, histone deacetylase (HDAC) inhibitors, histone methyltransferase EZH2 inhibitors, or bromodomain reader protein inhibitors may disable oncogenic gene expression signatures responsible for venetoclax resistance.

CD276 expression enables squamous cell carcinoma stem cells to evade immune surveillance.

Cell Stem Cell 2021 Apr 28. Epub 2021 Apr 28.

Laboratory of Molecular Signaling, Division of Oral Biology and Medicine, School of Dentistry, Jonsson Comprehensive Cancer Center and Broad Stem Cell Research Center, University of California, Los Angeles, Los Angeles, CA 90095, USA; Department of Bioengineering, Henry Samueli School of Engineering and Applied Science, University of California, Los Angeles, Los Angeles, CA 90095, USA. Electronic address:

Immunosurveillance is a critical mechanism guarding against tumor development and progression. Checkpoint inhibitors have shown significant success in cancer treatment, but expression of key factors such as PD-L1 in putative cancer stem cell (CSC) populations in squamous cell carcinoma has been inconclusive, suggesting that CSCs may have developed other mechanisms to escape immune surveillance. Here we show that CSCs upregulate the immune checkpoint molecule CD276 (B7-H3) to evade host immune responses. Read More

Lipid metabolism in cancer: New perspectives and emerging mechanisms.

Dev Cell 2021 May 3. Epub 2021 May 3.

Laboratory of Cellular Metabolism and Metabolic Regulation, VIB-KU Leuven Center for Cancer Biology, VIB, Leuven, Belgium; Laboratory of Cellular Metabolism and Metabolic Regulation, Department of Oncology, KU Leuven and Leuven Cancer Institute (LKI), Leuven, Belgium. Electronic address:

Tumors undergo metabolic transformations to sustain uncontrolled proliferation, avoid cell death, and seed in secondary organs. An increased focus on cancer lipid metabolism has unveiled a number of mechanisms that promote tumor growth and survival, many of which are independent of classical cellular bioenergetics. These mechanisms include modulation of ferroptotic-mediated cell death, support during tumor metastasis, and interactions with the cells of the tumor microenvironment. Read More

Improvement of Oral Bioavailability of Pyrazolo-Pyridone Inhibitors of the Interaction of DCN1/2 and UBE2M.

J Med Chem 2021 May 4. Epub 2021 May 4.

Department of Pharmaceutical Sciences, University of Kentucky, Lexington, Kentucky 40508, United States.

The cullin-RING ubiquitin ligases (CRLs) are ubiquitin E3 enzymes that play a key role in controlling proteasomal degradation and are activated by neddylation. We previously reported inhibitors that target CRL activation by disrupting the interaction of defective in cullin neddylation 1 (DCN1), a CRL neddylation co-E3, and UBE2M, a neddylation E2. Our first-generation inhibitors possessed poor oral bioavailability and fairly rapid clearance that hindered the study of acute inhibition of DCN-controlled CRL activity in vivo. Read More

COVID-19-related coagulopathy: a review of pathophysiology and pharmaceutical management.

Cell Biol Int 2021 May 4. Epub 2021 May 4.

Department of Hematology and Blood Banking, School of Allied Medical Sciences, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

December 2019 will never be forgotten in the history of medicine when an outbreak of pneumonia of unknown etiology in Wuhan, China sooner or later prompted the World Health Organization (WHO) to issue a public health warning emergency. This is not the first nor will it be the last time that a member of β-coronaviruses (CoVs) is waging a full-scale war against human health. Notwithstanding the fact that pneumonia is the primary symptom of the novel coronavirus (2019nCoV; designated as SARS-CoV-2), the emergence of severe disease mainly due to the injury of non-pulmonary organs at the shadow of coagulopathy leaves no choice, in some cases, rather than a dreadful death.

Immunological analysis of the murine anti-CD3-induced cytokine release syndrome model and therapeutic efficacy of anti-cytokine antibodies.

Eur J Immunol 2021 May 4. Epub 2021 May 4.

Light Chain Bioscience-Novimmune S.A., Chemin du Pré-Fleuri 15, 1228 Plan-Les-Ouates, Geneva, Switzerland.

The aberrant release of inflammatory mediators often referred to as a cytokine storm or cytokine release syndrome (CRS), is a common and sometimes fatal complication in acute infectious diseases including Ebola, dengue, COVID-19 and influenza. Fatal CRS occurrences have also plagued the development of highly promising cancer therapies based on T cell engagers and chimeric antigen receptor (CAR) T cells. CRS is intimately linked with dysregulated and excessive cytokine release including interferon γ (IFN-γ), tumor necrosis factor α (TNF-α), interleukin (IL) 1, IL-6 and IL-10 resulting in a systemic inflammatory response leading to multiple organ failure.
