N-glycosylation of SnRK2s affects NADPH maintenance in peroxisomes during prolonged ABA signalling.

Unfavourable conditions, such as prolonged drought and high salinity, pose a threat to the survival and agricultural yield of plants. The phytohormone ABA plays a key role in the regulation of plant stress adaptation and is often maintained at high levels for extended periods. While much is known about ABA signal perception and activation in the early signalling stage, the molecular mechanism underlying desensitization of ABA signalling remains largely unknown.

[Expression and significance of NF-κB and MIF in lung tissue of silicon-stained rats].

Objective: To investigate the distribution and expression of nuclear transcription factor(NF-κB) and macrophage migration inhibitory factor(MIF) in the lung tissue of rats exposed to silica.

Methods: Atotal of sixty-four adult rats aged 10 to 12 weeks(cleaning grade) were randomly divided into control group and silica dust group(32 rats each). At day 3, 7, 14, and 28 after modeling, 8 rats were randomly sacrificed in each group.
