    Yuanyuan Li1,#, Jinze Mu2,#, Qingliang Li1, Huabing Liu3, Xuefeng Yuan2,*, Deya Wang1,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.7, pp. 2079-2085, 2023, DOI:10.32604/phyton.2023.028237

    Abstract Infection of plum bark necrosis stem pitting associated virus (PBNSPaV) has been reported in many Prunus species in several countries, causing significant economic losses. The very small proteins encoded by plant viruses are often overlooked due to their short sequences and uncertain significance. However, numerous studies have indicated that they might play important roles in the pathogenesis of virus infection. The role of small hydrophobic protein P6, encoded by the open reading frame 2 of PBNSPaV, has not been well explored. In this study, we amplified the P6 fragment from a PBNSPaV isolate by RT-PCR using specific primers and found… More >

    Xi Liu1,2,#,*, Chuxuan Zhao2,#, Di Wang3,#, Gen Pan4, Xiaonan Ji2, Su Gao2, Tanxiao Du2, Yating Feng2, Wenjing Chen2

    Phyton-International Journal of Experimental Botany, Vol.92, No.7, pp. 2051-2064, 2023, DOI:10.32604/phyton.2023.028196

    Abstract Many studies have already shown that dwarfism and moderate delayed leaf senescence positively impact rice yield, but the underlying molecular mechanism of dwarfism and leaf senescence remains largely unknown. Here, using map-based cloning, we identified an allele of DEP2, DDG1, which controls plant height and leaf senescence in rice. The ddg1 mutant displayed dwarfism, short panicles, and delayed leaf senescence. Compared with the wild-type, ddg1 was insensitive to exogenous gibberellins (GA) and brassinolide (BR). DDG1 is expressed in various organs, especially in stems and panicles. Yeast two-hybrid assay, bimolecular fluorescent complementation and luciferase complementation image assay showed that DDG1 interacts… More >

    Rice E3 Ligase-Like Protein OsPIAL1 Positively Regulated the Drought Stress Response but Negatively Regulated the Salt Stress Response

    Sang Ik Song*

    Phyton-International Journal of Experimental Botany, Vol.92, No.7, pp. 2017-2034, 2023, DOI:10.32604/phyton.2023.027469

    Abstract Small ubiquitin-like modifier (SUMO) E3 ligases that facilitate the conjugation of SUMO proteins to target substrates contain an SP-RING domain which is like the RING domain found in ubiquitin E3 ligases. In this study, we isolated and characterized the Oryza sativa protein inhibitor of activated STAT like1 (OsPIAL1) containing SP-RING domains, as the rice homolog of Arabidopsis PIALs. OsPIAL1 interacts with OsSUMO proteins but does not interact with rice SUMO-conjugating enzymes (OsSCEs). An analysis of transgenic rice plant shows that OsPIAL1 is involved in SUMO conjugation to SCEs but not in SUMO conjugation to substrates. In addition, this OsPIAL1 activity… More >

    The zinc figure protein ZNF575 impairs colorectal cancer growth via promoting p53 transcription


    Oncology Research, Vol.31, No.3, pp. 307-316, 2023, DOI:10.32604/or.2023.028564

    Abstract Zinc-finger proteins play different roles in cancer; however, the function of zinc-finger protein ZNF575 in cancer remains unclear. In the present study, we aimed to determine the function and expression of ZNF575 in colorectal cancer. Proliferation assay, colony formation assay, and tumor model in mice were used to investigate the function of ZNF575 after ectopic expression of ZNF575 in colorectal cancer (CRC) cells. RNA sequencing, ChIP, and luciferase assays were used to investigate the mechanism behind ZNF575 regulation of CRC cell growth. The expression of ZNF575 was determined by IHC staining in 150 pairs of malignant CRC tissues, followed by… More > Graphic Abstract

    PPARα activator irbesartan suppresses the proliferation of endometrial carcinoma cells via SREBP1 and ARID1A


    Oncology Research, Vol.31, No.3, pp. 239-253, 2023, DOI:10.32604/or.2023.026067

    Abstract Endometrial carcinoma (EMC) is associated with obesity; however, the underlying mechanisms have not yet been elucidated. Peroxisome proliferator-activated receptor alpha (PPARα) is a nuclear receptor that is involved in lipid, glucose, and energy metabolism. PPARα reportedly functions as a tumor suppressor through its effects on lipid metabolism; however, the involvement of PPARα in the development of EMC remains unclear. The present study demonstrated that the immunohistochemical expression of nuclear PPARα was lower in EMC than in normal endometrial tissues, suggesting the tumor suppressive nature of PPARα. A treatment with the PPARα activator, irbesartan, inhibited the EMC cell lines, Ishikawa and… More >

    Calcyclin-binding protein contributes to cholangiocarcinoma progression by inhibiting ubiquitination of MCM2


    Oncology Research, Vol.31, No.3, pp. 317-331, 2023, DOI:10.32604/or.2023.028418

    Abstract Background: Cholangiocarcinoma (CCA) represents the epithelial cell cancer with high aggressiveness whose five-year survival rate is poor with standard treatment. Calcyclin-binding protein (CACYBP) shows aberrant expression within several malignant tumors, but the role of CACYBP in CCA remains unknown. Methods: Immunohistochemical (IHC) analysis was used to identify CACYBP overexpression in clinical samples of CCA patients. Moreover, its correlation with clinical outcome was revealed. Furthermore, CACYBP’s effect on CCA cell growth and invasion was investigated in vitro and in vivo using loss-of-function experiments. Results: CACYBP showed up-regulation in CCA, which predicts the dismal prognostic outcome. CACYBP had an important effect on… More >

    Protein-mediated interactions in the dynamic regulation of acute inflammation


    BIOCELL, Vol.47, No.6, pp. 1191-1198, 2023, DOI:10.32604/biocell.2023.027838

    Abstract Protein-mediated interactions are the fundamental mechanism through which cells regulate health and disease. These interactions require physical contact between proteins and their respective targets of interest. These targets include not only other proteins but also nucleic acids and other important molecules as well. These proteins are often involved in multibody complexes that work dynamically to regulate cellular health and function. Various techniques have been adapted to study these important interactions, such as affinity-based assays, mass spectrometry, and fluorescent detection. The application of these techniques has led to a greater understanding of how protein interactions are responsible for both the instigation… More >

    Minmin Xiao1, Moxiang Cheng1, Shuangquan Xie1, Xiushuang Wang1, Xingming Hao2, Li Zhuang1,*

    Phyton-International Journal of Experimental Botany, Vol.92, No.6, pp. 1841-1857, 2023, DOI:10.32604/phyton.2023.027369

    Abstract To clarify the characteristics of photoinhibition and the primary defense mechanisms of ephemeral plant leaves against photodestruction under high temperature stress, inhibitors and the technology to determine chlorophyll fluorescence were used to explore the protective effects of D1 protein turnover and the lutein cycle in the high temperature stress of the leaves of three ephemeral plants. The results showed that the maximum light conversion efficiency (Fv/Fm) of the ephemeral plant leaves decreased, and the initial fluorescence (Fo) increased under 35°C ± 1°C heat stress for 1–4 h or on sunny days in the summer. Both Fv/Fm and Fo could be… More >
