Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level

Aging and Cancer, EarlyView.
This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Uncovering G Protein‐Coupled Receptors: Novel Targets and Biomarkers for Predicting Glioma Prognosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Low‐grade gliomas (LGG) exhibit significant heterogeneity and recurrence risk. G protein‐coupled receptors (GPCR) contribute to glioma malignant progression, but their prognostic value remains unclear. This work attempts to formulate a GPCR‐based outcome‐predicting model for LGG. Methods Based on TCGA LGG data, the enrichment scores

Abscisic acid promotes development of somatic embryos on converted somatic embryos of Corydalis yanhusuo (Fumariaceae)

, 2012
Converted somatic embryos of Corydalis yanhusuo showed direct development of somatic embryos in the region at the junction of cotyledonary leaf and root when cultured on Murashige and Skoog (MS) basal medium supplemented with 0-16 mg/L abscisic acid (ABA)

Artificial seed from Pinus patula somatic embryos [PDF]

, 2002
Somatic and zygotic embryos of Pinus patula Scheide et Deppe. were encapsulated in 2.2% sodium alginate to examine the potential of producing artificial seeds. The alginate beads were supplemented with sucrose, maltose and activated charcoal.

Direct somatic embryogenesis from mature embryos of sandalwood

, 2002
Plants were regenerated from mature zygotic embryos of sandalwood (Santalum album L.) through direct somatic embryogenesis. Somatic embryos were formed directly without any intervening callus phase on zygotic embryos plated on Murashige and Skoog (MS ...

Engineered Nanotopography to Modulate Growth and Signaling of Neuronal Networks

Advanced Functional Materials, EarlyView.
This study examines the interaction between neurons and nanoscale topographies on engineered substrates. Neurons cultured on nanowires, nanopillars and nanoneedles exhibit enhanced neurite outgrowth, form more organized neuronal circuits, and display improved synaptic connectivity, compared to flat substrates.

Genetic Normalization of Differentiating Aneuploid Human Embryos [PDF]

, 2011
Early embryogenesis involves a series of dynamic processes, many of which are currently not well described or understood. Aneuploidy and aneuploid mosaicism, a mixture of aneuploid and euploid cells within one embryo, in early embryonic development are ...
