Cuticular waxes synthesised in the endoplasmic reticulum of epidermal cells must be exported to the outer surface of the epidermis to fulfil their barrier function. Beyond transmembrane trafficking mediated by ABC transporters, little is known about the movement of wax molecules. In this study, we characterise a mutant named sugar-associated vitrified 1 (sav1), which exhibits a vitrified phenotype and displays a reduced root length when cultivated on sugar-free medium.

Article Synopsis
  • Atherosclerosis (AS) is a prevalent condition leading to high rates of illness and death, with a study exploring the effects of Uyghur medicines quince and basil in treating AS.
  • Researchers used network pharmacology and bioinformatics to identify four key genes involved in the anti-AS effects of these herbs and conducted experiments to validate their findings.
  • The study confirmed that the co-administration of quince and basil significantly impacts the expression of these hub genes (COL1A1, COL3A1, BGLAP, NOX4), supporting their potential use in treating Atherosclerosis.

Background: The aim of this study was to assess homologous recombination deficiency (HRD) status and its correlation with carboplatin treatment response in early triple-negative breast cancer (TNBC) patients.

Methods: Tumor tissues from 225 consecutive TNBC patients were evaluated with an HRD panel and homologous recombination-related (HRR) gene expression data. HRD positivity was defined as a high HRD score and/or BRCA1/2 pathogenic or likely pathogenic mutation.

The aim of this study was to evaluate the mutation spectrum of homologous recombination repair (HRR) genes and its association with tumor immune infiltration and prognosis in triple-negative breast cancer (TNBC). TNBC patients (434 patients from Ruijin cohort) were evaluated with targeted next-generating sequencing for mutations in HRR genes. The frequencies of mutations were compared with public reference cohorts (320 TNBC patients from METABRIC, 105 from TCGA, and 225 from MSKCC 2018).

Photodynamic therapy (PDT) is a promising cancer treatment. This study investigated the antitumor effects and mechanisms of a novel photosensitizer meso-5-[ρ-diethylene triamine pentaacetic acid-aminophenyl]-10,15,20-triphenyl-porphyrin (DTP) mediated PDT (DTP-PDT). Cell viability, reactive oxygen species (ROS), and apoptosis were measured with a Cell Counting Kit-8 assay, DCFH-DA fluorescent probe, and Hoechst staining, respectively.

The mechanism of total polyphenols of Cydonia oblonga Miller(TPCOM) against kidney cancer was elucidated through a combination of network pharmacology, bioinformatics, and experimental verification. The active polyphenolic compounds from C. oblonga were screened by network pharmacological techniques and kidney cancer-related targets were collected through the database.

FTY720 is an analog of sphingosine-1-phosphate (S1P) derived from the ascomycete Cordyceps sinensis. As a new immunosuppressant, FTY720 is widely used to treat multiple sclerosis. FTY720 binds to the S1P receptor after phosphorylation, thereby exerting immunosuppressive effects.

Chronic myeloid leukemia (CML) is a malignant clonal disease involving hematopoietic stem cells that is characterized by myeloid cell proliferation in bone marrow and peripheral blood, and the presence of the Philadelphia (Ph) chromosome with BCR-ABL fusion gene. Treatment of CML has dramatically improved since the advent of tyrosine kinase inhibitors (TKI). However, there are a small subset of CML patients who develop resistance to TKI.

This study investigated the grouped and individualized load-velocity profile (GLVP ILVP) in Bulgarian split squat using Smith machine and free weight. Seventy five recreational male lifters completed two incremental loading tests of Bulgarian split squat. Mean velocity was measured by a linear-position transducer (GymAware).

Background: Lung adenocarcinoma (LUAD) has high morbidity and is prone to recurrence. TIMELESS (TIM), which regulates circadian rhythms in Drosophila, is highly expressed in various tumors. Its role in LUAD has gained attention, but the detailed function and mechanism have not been clarified completely at present.

Background: Overaccumulation of chloride (Cl) when plants suffer NaCl causes cell damage and death, and is regulated by Cl channel protein (CLC). Apple roots are very sensitive to Cl, but information associated with CLC is limited in apple crop that widely cultivated in the world.

Results: We identified 9 CLCs from the apple genome and divided them into two subclasses.

The aim of this study was to determine the optimal velocity loss (VL) threshold that maximises the post activation potentiation (PAP) stimulus for achieving larger and more consistent performance gains in track and field athletes. Twenty-two athletes from athletics participated in four back squat PAP tests with four different VL threshold (5%, 10%, 15% and 20% VL) at an intensity of 85%1RM. Countermovement jump (CMJ) height, power, and momentum were assessed before, and 10 s, 4, 8, 12, 16 minutes after the PAP condition.

Malus is an economically important plant that is widely cultivated worldwide, but it often encounters saline-alkali stress. The composition of saline-alkali land is a variety of salt and alkali mixed with the formation of alkaline salt. Hydrogen sulfide (HS) has been reported to have positive effects on plant responses to abiotic stresses.

According to clinical investigations, sleep disruption (SD) can influence the immune system and cause inflammatory bowel disease (IBD). However, the detailed effects of sleep on IBD development and progression have not been clarified. Here, we used dextran sulfate sodium (DSS) to induce colitis in mice, and then interfered with SD (day-time 8:00 a.

Enteromorpha prolifera polysaccharide (EP) has been shown to exhibit hypolipidemic and hypoglycemic activities in various experimental models. Here, an H-NMR-based metabolomic study was conducted to explore the regulatory effects of EP on serum metabolic changes in obese hamsters. High-fat diet (HFD)-fed hamsters were orally administrated with EP (300, 450, or 600 mg/kg) once daily for 12 weeks.

To investigate whether polysaccharides from Enteromorpha prolifera (EPP) could protect against acute hepatic injury induced by CCl, ICR mice were pretreated with EPP (150, 300, and 450 mg kg) and silymarin (100 mg kg) for 28 days before CCl induction. Pretreatment with EPP attenuated CCl-induced elevated serum transaminase activities and histopathological alterations in the liver. In addition, EPP prevented CCl-induced reduction of protein levels of phosphorylated nuclear factor E2-related factor 2 (p-Nrf2)/Nrf2, heme oxygenase-1 (HO-1), and mRNA levels of NADPH quinineoxidoreductase-1 (NQO-1), which, in turn, reduced hepatic oxidative stress injury.
