NAA enhances cell yields by inhibiting apoptosis pathway

ABSTRACT: The in vitro cell culturing witnessed its applications in both scientific research and industrial activities, its optimization leads to practical benefits, either through shortening the doubling time, or simplification of engineering requests, or both. Literature searching highlighted a role of a synthetic auxin derivative 1-Naphthaleneacetic acid (NAA) in optimizing plant cell culturing. Here, by measuring cell counts and their activities via CCK8 tests, we observed an up to 2-fold increase in the yield of in vitro cultured human cells. We tested different types of human cell lines and primary natural killer cells, found that NAA was effective in all the cells tested. The PI staining and FACS analysis suggested that NAA did not affect the cell cycling. Apoptosis-specific dye staining analysis implicated that NAA rescued cell death. We further did bulk RNA sequencing and identified the lipid metabolism-engaging and anti-apoptosis gene, ANGPTL4, was enhanced in expression upon NAA treatment. Studies on ANGPTL4 knockout cells indicated that ANGPTL4 is required for NAA-mediated response. Thus, our data identified a beneficial role of NAA in human cell culturing and highlighted its potency in the in vitro cell culturing

Grape berry: control vs NAA-treated

Project description:Transcriptional profiling comparing untreated berries (control) with berries treated with NAA (1-Naphthalene acetic acid, an auxin) at the preveraison stage. Two-condition experiment: control vs. treated. Comparisons were as follows: NAA-treated berries at 60 (days after full bloom (DAFB)) versus untreated berries at 60 DAFB (2 biological replicates, both dye-swapped), NAA-treated berries at 60 DAFB versus NAA-treated berries at 110 DAFB (2 biological replicates, only one dye-swapped), NAA-treated berries at 110 DAFB versus untreated berries at 110 DAFB (2 biological replicates, only one dye-swapped), and NAA-treated berries at 148 DAFB versus untreated berries at 110 DAFB (2 biological replicates, only one dye-swapped).

Expression data from Arabidopsis seedlings upon LRIS using NAA (1-Naphthaleneacetic acid) or non-auxin-like lateral root inducer naxillin

Project description:The acquisition of water and nutrients by plant roots is a fundamental aspect of agriculture and strongly depends on root architecture. Root branching and expansion of the root system is achieved through the development of lateral roots and is to a large extent controlled by the plant hormone auxin. However, the pleiotropic effects of auxin or auxin-like molecules on root systems complicate the study of lateral root development. Here we describe a small-molecule screen in Arabidopsis thaliana that identified naxillin as what is to our knowledge the first non-auxin-like molecule that promotes root branching. By using naxillin as a chemical tool, we identified a new function for root cap-specific conversion of the auxin precursor indole-3-butyric acid into the active auxin indole-3-acetic acid and uncovered the involvement of the root cap in root branching. Delivery of an auxin precursor in peripheral tissues such as the root cap might represent an important mechanism shaping root architecture. To further explore the specificity of naxillin for lateral root development, we compared the early effects of naxillin at the transcriptome level with NAA (1-Naphthaleneacetic acid) in roots of 3-day-old seedlings after 2-h and 6-h treatment. Arabidopsis thaliana (L). Heynh., Col-0 seeds were germinated vertically on solid medium derived from standard MS medium supplemented with 10 μM NPA (1-N-Naphthylphthalamic acid). Three days after germination, plants were transferred to 10 μM NAA (1-Naphthaleneacetic acid) or 50 μM naxillin for 2 and 6 hours. Plants were sampled before (Roots at T0, NPA) or after treatment (Roots at T1 and T2). RNA isolation was performed on 500 root sections (only root without meristems) for each sample. All sampling points were performed in three independent experiments.

A transcript profile of Medicago truncatula 2HA tissue culture with auxin treatment

Project description:Leaf explants of the superembryogenic Medicago truncatula line 2HA were treated with auxin (1-naphthaleneacetic acid) for one week to induce the formation of roots (Imin et al J Exp Bot 58:439-451). Gene expression in the leaves and the NAA treated tissue cultures was compared to identify transcripts expressed during the commitment to root formation in tissue culture. We have used the Affymetrix Medicago Genome Array GeneChip to compared gene expression in Medicago truncatula leaves and leaf explants that have been cultured for one week on NAA, to identify genes expressed during the commitment to root formation in tissue culture. Keywords: Cell type comparison
