Nitric oxide (NO) and hydrogen sulfide (H2S) are two signaling molecules that are endogenously generated in plant cells under physiological and stressful conditions. They perform their functions either through post-translational modifications (PTMs) of proteins as well as their interaction with other signaling molecules such as hydrogen peroxide (H2O2) or melatonin as well as with phytohormones.

    Nitric oxide and hydrogen sulfide share regulatory functions in higher plant events

    FRANCISCO J. CORPAS*, SALVADOR GONZÁLEZ-GORDO, MARTA RODRÍGUEZ-RUIZ, MARÍA A. MUÑOZ-VARGAS, JOSÉ M. PALMA
    BIOCELL, Vol.46, No.1, pp. 1-5, 2022, DOI:10.32604/biocell.2021.017300
    Abstract Nitric oxide (NO) and hydrogen sulfide (H2S) are two molecules that share signaling properties in plant and animal cells. NO and H2S originate two families of derived molecules designated reactive nitrogen and sulfur species (RNS and RSS, respectively). These molecules are responsible for certain protein regulatory processes through posttranslational modifications (PTMs), being the most remarkable S-nitrosation and persulfidation, which affect the thiol group of cysteine residues. NO and H2S can also exert regulatory functions due to their interaction through the iron present in proteins that contain heme groups or iron-sulfur clusters, as reported mainly in animal cells. However, the available… More >

    Single-cell systems neuroscience: A growing frontier in mental illness

    SEAN J. O’SULLIVAN1,2,*
    BIOCELL, Vol.46, No.1, pp. 7-11, 2022, DOI:10.32604/biocell.2022.017680
    Abstract The development of effective treatments for psychiatric disease has been disappointing in recent decades given the advancements in neuroscience. Moreover, rising rates of mental illness such as addiction and depression compel scientists and physicians to discover novel and creative solutions. One such approach that has proven effective is systems neuroscience: A focus on networks as opposed to mechanism. Further, investigation at the single-cell and circuit level is likely to be fruitful in such endeavors as this resolution describes the functional psychopathology that allows for intervention.

    (This article belongs to this Special Issue: Noncoding RNAs & Associated Human Diseases)
    Abstract MicroRNA-153 (miR-153), belongs to a class of small non-coding RNA. It is a critical regulator of gene expression at the post-transcriptional level which interacts with the functional mRNA at 3’UTR region and suppresses the expression of the mRNA. More recently, it has become apparent that changes in the miR-153 expression lead to invasion, metastasis, angiogenesis and various types of tumor progression. This review summarizes the connection between dysregulation of miR-153 and various types of cancer progression. miR-153 regulates various signaling pathways to inhibit the proliferation and induce apoptosis in the cancer cell and also show synergistic activity with anticancer drugs.… More >

    Abstract Brain arteriovenous malformations (AVMs) are abnormal vessels that are prone to rupture, causing life-threatening intracerebral hemorrhage (ICH). Understanding the molecular basis of pathogenesis, timely diagnosis, and treatment of brain AVMs are some of the urgent problems in neurosurgery. MicroRNAs (miRNAs) are small endogenous RNAs that regulate gene-expression posttranscriptionally. MiRNAs are involved in almost all biological processes, including cell proliferation, apoptosis, and cell differentiation. Recent studies have shown that miRNAs can be involved in brain AVMs formation and rupture. There are also extracellular forms of miRNAs. Circulating miRNAs have been detected in the blood circulation and other body fluids. Owing to… More >

    (This article belongs to this Special Issue: Oxidative Stress in Aquatic Organisms)
    Abstract Oxidative stress is a critical condition derived from the imbalance between the generation of reactive oxygen species and the sophisticated network of antioxidant mechanisms. Several pollutants and environmental factors can affect this system through connected mechanisms, indirect relationships, and cascade effects from pre-transcriptional to catalytic level, by either enhancing intracellular ROS formation or impairing antioxidant defenses. This review summarizes the current knowledge on the pro-oxidant challenges from emerging environmental stressors threatening marine organisms, such as pharmaceuticals, microplastics and climate-related ocean changes. Emphasis will be placed on oxidative pathways, including signaling proteins and transcription factors involved in regulation of antioxidant responsiveness.… More >

    Abstract Metabolic reprogramming and immunologic suppression are two critical characteristics promoting the progression of head and neck squamous cell carcinoma (HNSCC). The integrative analysis of all the metabolism-related genes (MRGs) in HNSCC is lacking and the interaction between the metabolism and the immune characteristics also requires more exploration to uncover the potential mechanisms. Therefore, this study was designed to establish a prognostic signature based on all the MRGs in HNSCC. Genes of HNSCC samples were available from the TCGA and GEO databases while the MRGs were retrieved from a previous study. Ultimately 4 prognostic MRGs were selected to construct a model… More >

    Abstract Sorafenib, a multikinase inhibitor used for the treatment of hepatocellular carcinoma, is limited by its low oral bioavailability. To overcome this drawback, we have developed novel camel milk casein-derived nanoparticles as a drug delivery system. Camel milk casein is not only biocompatible on oral administration but is actually a dietary protein of pharmaceutical relevance. Casein is used because of its amphiphilic nature, self-assembling property, ability to show sustained release, and capability of encapsulating both hydrophilic and hydrophobic drugs. In this study, camel milk casein nanoparticles loaded with sorafenib were developed and characterized. Characterization of casein nanoparticles was done by dynamic… More >

    Abstract Acute myeloid leukemia (AML) is regarded as a stem cell disease. However, no one unique marker is expressed on leukemia stem cells (LSC) but not on leukemic blasts nor normal hematopoietic stem cells (HSC). CD34+ CD38- with or without CD123 or CD44 subpopulations are immunophenotypically defined as putative LSC fractions in AML. Nevertheless, markers that can be effectively and simply held responsible for the intrinsical heterogeneity of LSC is still unclear. In the present study, we examined the frequency of three different LSC subtypes (CD34+ CD38-, CD34+ CD38- CD123+ , CD34+ CD38- CD44+ ) in AML at diagnosis. We then… More >

    Abstract The concentration of cell-free fetal DNA fragments should be detected before noninvasive prenatal testing (NIPT). The fetal DNA molecules have significant clinical potential in determining the overall performance of NIPT and clinical interpretation. It is important to measure fetal DNA fraction before NIPT. However, there is still little research on how to calculate the concentration of female fetuses. Two estimation approaches were proposed to calculate fetal DNA fraction, including the fragments size-based approach, aneuploid-based approach, which are all approaches based on chromosome segments. Based on high-throughput sequencing data, two approaches to calculate the DNA fraction of male fetuses were tested… More >

    Abstract Kadsura coccinea (Lem.) is a woody wine plant with a peculiar fruit enriched in important health-promoting compounds. The non-editable part of the fruit, i.e., the seed and peel, represents more than 60% of the fruit and is considered a biowaste. This significantly restricts the development of the K. coccinea fruit industry. Clarifying the metabolic components of the different fruit parts can help to improve the utilization rate and valorization of K. coccinea. Herein, we evaluated K. coccinea fruit peel, pulp, and seed using widely-targeted metabolomics and quantified a set of 736 bioactive compounds from 11 major metabolite classes. The most… More >
