Evidence of cellular senescence during the development of estrogen-induced pituitary tumors
(BioScientifica, 2015-03)
Although pituitary adenomas represent 25% of intracranial tumors, they are usually benign, with the mechanisms by which these tumors usually avoid an invasive profile and metastatic growth development still remaining ...
Autocrine IL-6 mediates pituitary tumor senescence
(Impact Journals LLC, 2017-01)
Cellular senescence is a stable proliferative arrest state. Pituitary adenomas are frequent and mostly benign, but the mechanism for this remains unknown. IL-6 is involved in pituitary tumor progression and is produced by ...
Tumor-induced senescent T cells with suppressor function: A potential form of tumor immune evasion
(American Association for Cancer Research, 2008-02)
Senescent and suppressor T cells are reported to be increased in select patients with cancer and are poor prognostic indicators. Based on the association of these T cells and poor outcomes, we hypothesized that tumors ...
Nitrogen fertilization increases ammonium accumulation during senescence of barley leaves
(Springer Heidelberg, 2016-04)
Leaf senescence is a developmental process characterized by two events: (1) dismantling of the photosynthetic apparatus and, (2) nitrogen remobilization to other parts of the plant. Ammonium accumulation during senescence ...
The degradation of chloroplast components during postharvest senescence of broccoli florets is delayed by low-intensity visible light pulses
(Elsevier Science, 2020-10)
Senescence in harvested green organs, such as broccoli inflorescences, is a highly regulated process characterized by a massive degradation of chloroplast components. The dismantling of the chloroplast involves small ...
Leaf Senescence: The Chloroplast Connection Comes of Age
(Multidisciplinary Digital Publishing Institute, 2019-11)
Leaf senescence is a developmental process critical for plant fitness, which involves genetically controlled cell death and ordered disassembly of macromolecules for reallocating nutrients to juvenile and reproductive ...
Leaf protein allocation across the canopy and during senescence in earlier and later senescing maize hybrids, and implications for the use of chlorophyll as a proxy of leaf N
(Springer, 2019-09)
Leaf chlorophyll (chl) and protein distribution were analyzed throughout grain filling in four modern maize hybrids with contrasting senescence behavior, at three different canopy levels and at low-N (LN, 18 kg N ha−1) and ...
Sunflower Leaf Senescence: A Complex Genetic Process with Economic Impact on Crop Production
(IntechOpen, 2017)
Leaf senescence is a complex process controlled by multiple genetic and environmental variables. In different crops, a delay in leaf senescence has an important impact on grain yield trough the maintenance of the photosynthetic ...
Network and biosignature analysis for the integration of transcriptomic and metabolomic data to characterize leaf senescence process in sunflower
(2016)
In recent years, high throughput technologies have led to an increase of datasets from omics disciplines allowing the understanding of the complex regulatory networks associated with biological processes.
Leaf senescence ...
