Effect of different exogenous sugars on the growth and nutrient uptake of Borkh. under sub-low root zone temperature.

In northern China, soil temperature slowly rises in spring, often subjecting apple roots to sub-low-temperature stress. Sugar acts as both a nutrient and signaling molecule in roots in response to low-temperature stress. To explore the effects of exogenous sugars on the growth and nutrient absorption of Borkh.

AIM2 upregulation promotes metastatic progression and PD-L1 expression in lung adenocarcinoma.

Cancer metastasis leading to the dysfunction of invaded organs is the main cause of the reduced survival rates in lung cancer patients. However, the molecular mechanism for lung cancer metastasis remains unclear. Recently, the increased activity of inflammasome appeared to correlate with the metastatic progression and immunosuppressive ability of various cancer types.

The aberrant cancer metabolic gene carbohydrate sulfotransferase 11 promotes non-small cell lung cancer cell metastasis via dysregulation of ceruloplasmin and intracellular iron balance.

Aberrant metabolism has been proposed as one of the emerging hallmarks of cancer. However, the interplay between metabolic disorders and cancer metastasis remains to be defined. To explore the sophisticated metabolic processes during metastatic progression, we analyzed differentially expressed metabolic genes during the epithelial-mesenchymal transition (EMT) of lung cancer cells and defined the EMT-associated metabolic gene signature in lung adenocarcinoma patients.

Dehydroepiandrosterone (DHEA) Sensitizes Irinotecan to Suppress Head and Neck Cancer Stem-Like Cells by Downregulation of WNT Signaling.

Purpose: Current treatment options for head and neck squamous cell carcinoma (HNSCC) are limited, especially for cases with cancer stem cell-induced chemoresistance and recurrence. The WNT signaling pathway contributes to maintenance of stemness translocation of β-catenin into the nucleus, and represents a promising druggable target in HNSCC. Dehydroepiandrosterone (DHEA), a steroid hormone, has potential as an anticancer drug.

FAS receptor regulates NOTCH activity through ERK-JAG1 axis activation and controls oral cancer stemness ability and pulmonary metastasis.

Pulmonary metastasis occurring via the colonization of circulating cancer stem cells is a major cause of oral squamous cell carcinoma (OSCC)-related death. Thus, understanding the mechanism of OSCC pulmonary metastasis may provide a new opportunity for OSCC treatment. FAS, a well-known apoptosis-inducing death receptor, has multiple nonapoptotic, protumorigenic functions.

Synthesis, Characterization and Crystal Structures of Fluoro-Substituted Aroylhydrazones with Antimicrobial Activity.

A series of five new fluoro-substituted aroylhydrazones were prepared and structurally characterized by elemental analysis, IR, UV-Vis and 1H NMR spectroscopy, as well as single crystal X-ray diffraction. The compounds were evaluated for their antibacterial (Bacillus subtilis, Staphylococcus aureus, Escherichia coli, and Pseudomonas fluorescence) and antifungal (Candida albicans and Aspergillus niger) activities by MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) method. The biological assay indicated that the presence of the electron-withdrawing groups in the aroylhydrazones improved their antimicrobial activities.

Effects of regular breakfast habits on metabolic and cardiovascular diseases: A protocol for systematic review and meta-analysis.

Background: Breakfast, which is considered as an important meal of the day, is being ignored by an increasing number of people as the pace of modern life accelerates. Although a large number of previous studies have reported the relationship between skipping breakfast and type 2 diabetes mellitus, most of them were cross-sectional studies. It remains unclear how skipping breakfast affects such specific cardio-metabolic diseases as hypertension, strokes and hypercholesterolemia.

Cdc25A inhibits autophagy-mediated ferroptosis by upregulating ErbB2 through PKM2 dephosphorylation in cervical cancer cells.

Methods: The transcript and protein expression of Hsp90 in normal cervical and HPV16 cervical cancer tissues and cell lines were detected by qRT-PCR, immunohistochemistry staining and Western blot.

Extract Induces Selective Killing, Necrosis, and Apoptosis in Oral Cancer Cells.

Ethyl acetate extract (EANT) from shows antiproliferation and apoptosis but not necrosis in breast cancer cells, but this has not been investigated in oral cancer cells. In the present study, EANT shows no cytotoxicity to normal oral cells but exhibits selective killing to six oral cancer cell lines. They were suppressed by pretreatment of the antioxidant inhibitor -acetylcysteine (NAC), demonstrating that EANT-induced cell death was mediated by oxidative stress.

Synthesis, Characterization, Crystal Structures, and Urease Inhibition of Copper(II) and Zinc(II) Complexes Derived from Benzohydrazones.

A new copper(II) complex [Cu(L1)(NCS)(CH3OH)] (1) and a new zinc(II) complex [ZnCl2(HL2)]·CH3OH (2), derived from 4-bromo-N'-(pyridin-2-ylmethylene)benzohydrazide (HL1) and 4-methoxy-N'-(pyridin-2-ylmethylene)benzohydrazide (HL2), were prepared and characterized by elemental analysis, IR and UV-Vis spectroscopy and single crystal X-ray diffraction. The hydrazone HL1 coordinates to the Cu atom in enolate form, while the hydrazone HL2 coordinates to the Zn atom in carbonyl form. Single crystal structural analyses indicate that the hydrazones coordinate to the metal atoms through the pyridine N, imino N, and enolate/carbonyl O atoms.

[Physiological and biochemical mechanism of spermidine improving drought resistance in maize seedlings under drought stress.].

To explore the role of exogenous spermidine (Spd) in enhancing the resistance of maize to drought stress, 15% polyethylene glycol (PEG-6000) was used to simulate drought stress and with 'Xianyu 335' (drought-insensitive) and 'Fenghe 1' (drought sensitive) as the experiment materials, the effects of Spd (0.1 mmol·L) on the growth, photosynthetic characteristics, chlorophyll content, osmotic adjustment substance, membrane lipid peroxidation and root activity of maize seedlings were investigated. The results showed that the application of Spd significantly promoted the growth of maize seedlings under drought stress, increased chlorophyll content, net photosynthetic rate (P), stomatal conductance (g), transpiration rate (T) and water use efficiency (WUE), and decreased the enhancement of intercellular carbon dioxide concentration (C) in 'Fenghe 1'.

[Mechanisms of nitrous oxide emission during livestock manure aerobic composting].

Aerobic composting is an effective way to treat and recycle livestock manure. However, the aerobic composting of livestock manure is a potential source of the greenhouse gas nitrous oxide (N2O), which closely relates to the global greenhouse effect and ozone depletion. With the expansion of livestock industry and the dramatic increasing yield of manure compost, the N2O emission during the aerobic composting has become a severe problem.
