Copy number alterations identify a smoking-associated expression signature predictive of poor outcome in head and neck squamous cell carcinoma.

Cancer Genet 2021 May 28;256-257:136-148. Epub 2021 May 28.

Department of Biochemistry, Program in Cancer Cell Biology USA. Electronic address:

Cigarette smoking is a risk factor for the development of head and neck squamous cell carcinoma (HNSCC), partially due to tobacco-induced large-scale chromosomal copy-number alterations (CNAs). Identifying CNAs caused by smoking is essential in determining how gene expression from such regions impact tumor progression and patient outcome. We utilized The Cancer Genome Atlas (TCGA) whole genome sequencing data for HNSCC to directly identify amplified or deleted genes correlating with smoking pack-year based on linear modeling.

Department of Civil Engineering, University of Louisiana at Lafayette, Lafayette, LA, 70504, USA; Energy Institute of Louisiana, University of Louisiana at Lafayette, Lafayette, LA, 70504, USA. Electronic address:

This study investigated the adsorptive removal and subsequent degradation of sulfamethoxazole (SMX) from a synthetic urine by biochar (BC). The BCs used in this study were prepared using two different feedstocks with different temperatures. Element analysis and Fourier transform infrared spectroscopy (FTIR) results suggested that the aromaticity of one of the BCs, 700HSBC was significantly different from the 700PSBC although both of them were prepared at the same temperature (700 °C) with similar pore size distributions and specific surface areas.

Co-delivery of Phagocytosis Checkpoint Silencer and Stimulator of Interferon Genes Agonist for Synergetic Cancer Immunotherapy.

ACS Appl Mater Interfaces 2021 Jun 15. Epub 2021 Jun 15.

School of Biomedical Sciences and Engineering, South China University of Technology, Guangzhou International Campus, Guangzhou 511442, P.R. China.

Efficient capture and presentation of tumor antigens by antigen-presenting cells (APCs), especially dendritic cells (DCs), are crucial for activating the anti-tumor immunity. However, APCs are immunosuppressed in the tumor microenvironment, which hinders the tumor elimination. To reprogram APCs for inducing strong anti-tumor immunity, we report here a co-delivery immunotherapeutic strategy targeting the phagocytosis checkpoint (signal regulatory protein α, SIRPα) and stimulator of interferon genes (STING) of APCs to jointly enhance their ability of capturing and presenting tumor antigens.

Atherogenic oxoaldehyde of cholesterol induces innate immune response in monocytes and macrophages.

Cell Biochem Biophys 2021 Jun 15. Epub 2021 Jun 15.

Departments of Environmental Toxicology, College of Sciences and Engineering, Southern University and A & M College, Baton Rouge, LA, 70813, USA.

Cholesterol oxidation product, 3β-hydroxy-5-oxo-5,6-secocholestan-6-al (cholesterol 5,6-secosterol, ChSeco or Atheronal-A), formed at inflammatory sites, has been shown to promote monocyte differentiation into macrophages and cause elevated expression of macrophage scavenger receptors. Since inflammation is a key event at all stages of atherosclerotic plaque formation, the pro-inflammatory actions of ChSeco in human THP-1 monocytes and mouse J774 macrophages were investigated in the present study by employing ELISA, qRT-PCR, and functional assays. An increase in the secretion of interleukin-8 and platelet-derived growth factor (PDGF) isoform AA and, to a limited extent, PDGF isoform BB was observed into the culture medium of THP-1 monocytes exposed to ChSeco.

The Key Laboratory of Plant Development and Environmental Adaptation Biology, Ministry of Education, School of Life Sciences, Shandong University, Qingdao, 266237, China.

Nitrate is both an important nutrient and a critical signaling molecule that regulates plant metabolism, growth, and development. Although several components of the nitrate signaling pathway have been identified, the molecular mechanism of nitrate signaling remains unclear. Here, we showed that the growth-related transcription factors HOMOLOG OF BRASSINOSTEROID ENHANCED EXPRESSION2 INTERACTING WITH IBH1 (HBI1) and its three closest homologs (HBIs) positively regulate nitrate signaling in Arabidopsis thaliana.

Transcriptional upregulation of host-specific terpene metabolism in aphid-induced galls of Pistacia palaestina.

J Exp Bot 2021 Jun 15. Epub 2021 Jun 15.

Institute of Plant Sciences, Newe Ya'ar Research Center, Agricultural Research Organization, The Volcani Center, Ramat Yishay, Israel.

Galling insects gain food and shelter by inducing specialized anatomical structures in their plant hosts. Such galls often accumulate plant defensive metabolites protecting the inhabiting insects from predation. We previously found that, despite a marked natural chemopolymorphism in natural populations of Pistacia palaestina, the monoterpene levels in Baizongia pistaciae induced galls is substantially higher than in leaves of their hosts.

MOA Key Laboratory of Crop Ecophysiology and Farming System in the Middle Reaches of the Yangtze River, Huazhong Agricultural University, Wuhan, China.

CCaMKs and MAPKKs are two kinases that regulate salt stress response in plants. It remains unclear, however, how they cooperatively affect the lateral root growth under salt stress. Here, two conserved phosphorylation sites (S102 and T118) of OsCaM1 were identified, and affected the capability of binding to Ca 2+  in vitro and kinase activity of OsCCaMK in vivo. Read More

Dynamic innate immune response determines susceptibility to SARS-CoV-2 infection and early replication kinetics.

J Exp Med 2021 Aug 15;218(8). Epub 2021 Jun 15.

Department of Laboratory Medicine, Yale School of Medicine, New Haven, CT.

Initial replication of SARS-CoV-2 in the upper respiratory tract is required to establish infection, and the replication level correlates with the likelihood of viral transmission. Here, we examined the role of host innate immune defenses in restricting early SARS-CoV-2 infection using transcriptomics and biomarker-based tracking in serial patient nasopharyngeal samples and experiments with airway epithelial organoids. SARS-CoV-2 initially replicated exponentially, with a doubling time of ∼6 h, and induced interferon-stimulated genes (ISGs) in the upper respiratory tract, which rose with viral replication and peaked just as viral load began to decline.

Neuroprotective effects of bone marrow Sca-1 cells against age-related retinal degeneration in OPTN E50K mice.

Cell Death Dis 2021 Jun 15;12(6):613. Epub 2021 Jun 15.

Department of Ophthalmology, The Second Affiliated Hospital of Harbin Medical University, Harbin, China.

Glaucoma is characterized by retinal ganglion cell (RGC) death, the underlying mechanisms of which are still largely unknown. An E50K mutation in the Optineurin (OPTN) gene is a leading cause of normal-tension glaucoma (NTG), which directly affects RGCs in the absence of high intraocular pressure and causes severe glaucomatous symptoms in patients. Bone marrow (BM) stem cells have been demonstrated to play a key role in regenerating damaged tissue during ageing and disease through their trophic effects and homing capability. Read More

Oxysterols Modify NLRP2 in Epithelial Cells, Identifying a Mediator of Ozone-induced Inflammation.

Am J Respir Cell Mol Biol 2021 Jun 14. Epub 2021 Jun 14.

University of North Carolina, Pediatrics, Chapel Hill, North Carolina, United States;

Ozone (O) is a prevalent air pollutant causing lung inflammation. Previous studies demonstrate that O oxidizes lipids, such as cholesterol, in the airway to produce oxysterols, such as secosterol-A (SecoA), which are electrophiles capable of forming covalent linkages preferentially with lysine residues and consequently modify protein function. The breadth of proteins modified by this oxysterol as well as the biological consequences in the lung are unknown. Read More

The miR-302c/transforming growth factor-β receptor type-2 axis modulates interleukin-1β-induced degenerative changes in osteoarthritic chondrocytes.

J Cell Commun Signal 2021 Jun 14. Epub 2021 Jun 14.

Department of Orthopedics, The Second Xiangya Hospital, Central South University, Changsha, People's Republic of China.

Chondrocyte production of catabolic and inflammatory mediators participating in extracellular matrix degradation has been regarded as a central event in osteoarthritis (OA) development. During OA pathogenesis, interleukin-1β (IL-1β) decreases the mRNA expression and protein levels of transforming growth factor-β receptor type-2 (TGFBR2), thus disrupting transforming growth factor-β signaling and promoting OA development. In the present study, we attempted to identify the differentially expressed genes in OA chondrocytes upon IL-1β treatment, investigate their specific roles in OA development, and reveal the underlying mechanism.
