Nitrogen assimilation and nitrate reductase activity in tomato seedlings. I. Comparative studies on the influence of the Ca:Mg ratio on nitrogen metabolism in relation to absorption of nitrates or ammonium salts

open access: yesActa Societatis Botanicorum Poloniae, 2015
A change in the Ca:Mg ratio in the nutrient solution from the value optimal for tomato growth (3:1) to an unsuitable value (3:30) increases several times Mg2+ accumulation with simultaneous reduction of Ca2+ accumulation independently from the absorption

The microbiome in human skin aging

open access: yesFEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

(52(3):238-246)Relationships between Ammonium Assimilation Enzyme Activities and Dry Weight Accumulation of Maize Seedling

open access: yes, 2010
本試驗以玉米自交系和單雜交種各四個為材料,於溫室環境下,利用細砂為栽培介質,並於玉米不同株齡期進行50mM NH4+ 溶液連續澆灌18天後,調查幼苗乾物累積重與其銨同化酵素活性之表現。結果顯示 GS (glutamine synthetase) 活性、地上部乾物累積重、根部乾物累積重、整株乾物累積重和地上部/根部比值呈現隨株齡之增大而增加之趨勢。基因型間乾物質之累積量以TA85-17H95最大,其次為A661,最小者為 ICAL210及 TA85-17。相關分析顯示地上部乾物累積重、根部乾物累積重 ...

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

open access: yesMolecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Dry Matter and Nitrogen Accumulation During Vegetative and Grain Filling of Lentil (Lens culinaris Medic.) as Affected by Nitrogen Rates

open access: yesNotulae Botanicae Horti Agrobotanici Cluj-Napoca, 2011
This research aimed to determine the effect of different levels of nitrogen (N) on the growth, yield and the N accumulation of lentil plants grown under rain-fed conditions.

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.

Effect of Extended Photoperiod with a Fixed Mixture of Light Wavelengths on Tomato Seedlings

open access: yesHortScience, 2020
Light is an abiotic factor, and its quality, quantity, and photoperiod can be modulated to work as eustress inductors to regulate plant processes.
