Liver-specific gene PGRMC1 blocks c-Myc-induced hepatocarcinogenesis through ER stress-independent PERK activation.

Roles of liver-specific genes (LSGs) in tumor initiation and progression are rarely explored in hepatocellular carcinoma (HCC). Here we show that LSGs are generally downregulated in HCC tumor tissues compared to non-HCC liver tissues, and low-LSG HCCs show poor prognosis and the activated c-Myc pathway. Among the c-Myc- and patient prognosis-associated LSGs, PGRMC1 significantly blocks c-Myc-induced orthotopic HCC formation.

Oncogenic Roles of Laminin Subunit Gamma-2 in Intrahepatic Cholangiocarcinoma via Promoting EGFR Translation.

Intrahepatic cholangiocarcinoma (iCCA) is a highly lethal biliary epithelial cancer in the liver. Here, Laminin subunit gamma-2 (LAMC2) with important oncogenic roles in iCCA is discovered. In a total of 231 cholangiocarcinoma patients (82% of iCCA patients) across four independent cohorts, LAMC2 is significantly more abundant in iCCA tumor tissue compared to normal bile duct and non-tumor liver.

Spark Plasma Sintering-Assisted Synthesis of BiFeO/BiFeO Heterostructures with Enhanced Photocatalytic Activity for Removal of Antibiotics.

Bismuth ferrite-based heterojunction composites have been considered as promising visible-light responsive photocatalysts because of their narrow band gap structure; however, the synthetic methods reported in the literature were usually time-consuming. In this study, we report a facile and quick preparation of bismuth ferrite-based composites by the hydrothermal method, combined with spark plasma sintering (SPS), a technique that is usually used for the high-speed consolidation of powders. The result demonstrated that the SPS-assisted synthesized samples possess significant enhanced photoelectric and photocatalytic performance.

Merkel cell carcinoma (MCC) is a rare cutaneous growth with aggressive nature. It mostly affects on the head and neck of white men aged 65 years old and immunosuppressed patients. Limited cases were reported in Asian patients.

Application of Baricitinib in Dermatology.

There are four JAK subtypes: JAK1, JAK2, JAK3, and tyrosine kinase 2 (TYK2). Small molecule Janus tyrosine kinase (JAK) inhibitors can inhibit a variety of pro-inflammatory cytokines. Baricitinib is the first generation of JAK1/2 inhibitor targeting the ATPase of JAK, which blocks the intracellular transmission of cytokines through JAK-STATs.

Bi-allelic variants in DNHD1 cause flagellar axoneme defects and asthenoteratozoospermia in humans and mice.

Asthenoteratozoospermia, defined as reduced sperm motility and abnormal sperm morphology, is a disorder with considerable genetic heterogeneity. Although previous studies have identified several asthenoteratozoospermia-associated genes, the etiology remains unknown for the majority of affected men. Here, we performed whole-exome sequencing on 497 unrelated men with asthenoteratozoospermia and identified DNHD1 bi-allelic variants from eight families (1.

Psoriasis to Psoriatic Arthritis: The Application of Proteomics Technologies.

Psoriatic disease (PsD) is a spectrum of diseases that affect both skin [cutaneous psoriasis (PsC)] and musculoskeletal features [psoriatic arthritis (PsA)]. A considerable number of patients with PsC have asymptomatic synovio-entheseal inflammations, and approximately one-third of those eventually progress to PsA with an enigmatic mechanism. Published studies have shown that early interventions to the very early-stage PsA would effectively prevent substantial bone destructions or deformities, suggesting an unmet goal for exploring early PsA biomarkers.

Nociceptive Sensory Fibers Drive Interleukin-23 Production in a Murine Model of Psoriasis Calcitonin Gene-Related Peptide.

Neuroimmunity is involved in the pathogenesis of psoriasis, but the mechanism underlying the interaction between the nervous system and the interleukin (IL)-23/IL-17 immune axis is yet unclear. This study reveals the essential role of the sensory neuron-derived calcitonin gene-related peptide (CGRP) in imiquimod (IMQ)-induced expression of IL-23. First, we show that the increased nociceptive behavior was consistent with the development of psoriasiform dermatitis, which requires intact sensory innervation.

NLK suppresses MAVS-mediated signaling in black carp antiviral innate immunity.

Mammalian Nemo-like kinase (NLK) plays important roles in multiple biological processes including immune response; however, the roles of teleost NLK remain largely unknown. In the present study, the NLK homolog (bcNLK) of black carp (Mylopharyngodon piceus) has been cloned and characterized. The coding region of bcNLK consists of 1427 nucleotides and encodes 476 amino acid, including two low complexity region (LCR) domains at the N-terminus and a serine/threonine protein kinase catalytic (S-TKc) domain in the middle region.

Catalytic Reductive Cross Coupling and Enantioselective Protonation of Olefins to Construct Remote Stereocenters for Azaarenes.

A novel enantioselective protonation protocol that is triggered by reductive cross coupling of olefins is reported. When under cooperative photoredox and chiral hydrogen-bonding catalytic conditions and using a terminal reductant, various α-branched vinylketones with diverse vinylazaarenes could provide important enantioenriched azaarene derivatives containing tertiary stereocenters at their remote δ-position with high yields and enantioselectivities. This reaction system is also suitable for α-branched vinylazaarenes, thus successfully assembling elusive 1,4-stereocenters.

Black carp TRADD suppresses MAVS/IFN signaling during the innate immune activation.

Tumor necrosis factor receptor 1 (TNFR1) associated death domain protein (TRADD) is a pivotal adaptor in TNF signaling pathway and up-regulates MAVS/IFN signaling pathway in human and mammal. However, the role of TRADD in teleost fish remains obscure. To reveal the function of teleost TRADD in the innate immune response, the TRADD homologue (bcTRADD) of black carp (Mylopharyngodon piceus) has been cloned and the function of bcTRADD is investigated in this study, which shares similar functional domain to its mammalian counterpart.

3D Urchin-Like CuO Modified WO Nanostructures for Promoted Photocatalytic Hydrogen Evolution under Visible Light Irradiation.

Photocatalytic hydrogen evolution is a promising" green chemistry" route driven by sunlight for the direct water splitting into value-added hydrogen energy. Herein, with the object of exploring the effect of CuO loading on WO photocatalytic activity, a 3D Urchin-like CuO modified WO (CuO/WO) microspheres with different CuO loadings were synthesized via thermochemical precipitation combined with solvent-thermal method. The obtained CuO/WO microspheres were analyzed by means of X-ray diffraction (XRD), scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDS), transmission electron microscope (TEM), X-ray photoelectron spectroscopy (XPS) and photoluminescence (PL), etc.

Whole-genome mate-pair sequencing of apparently balanced chromosome rearrangements reveals complex structural variations: two case studies.

Background: Apparently balanced chromosome rearrangements (ABCRs) in non-affected individuals are well-known to possess high reproductive risks such as infertility, abnormal offspring, and pregnancy loss. However, caution should be exercised in genetic counseling and reproductive intervention because cryptic unbalanced defects and genome structural variations beyond the resolution of routine cytogenetics may not be detected.

Case Presentation: Here, we studied two familial cases of ABCRs were recruited in this study.

Angioimmunoblastic T cell lymphoma (AITL)-associated hemophagocytic lymphohistiocytosis (HLH) rarely occurs with annular erythema multiforme-like rashes. The present case report describes a patient who was misdiagnosed with erythema multiforme at an early stage of the disease due to annular erythema multiforme-like eruptions. However, antihistamine treatment was ineffective.

C19, a C-terminal peptide of CKLF1, decreases inflammation and proliferation of dermal capillaries in psoriasis.

Psoriasis is a chronic inflammatory autoimmune disease with undefined etiology. Chemokine-like factor 1 (CKLF1), a human cytokine that is a functional ligand for CCR4, displays chemotactic activities in a wide spectrum of leukocytes and plays an important role in psoriasis development. In previous study, our laboratory found that the expression of CKLF1 increased in psoriatic lesions.
