A short-term chick embryo in vivo xenograft model to study retinoblastoma cancer stem cells

open access: yesIndian Journal of Ophthalmology, 2022
Purpose: Cancer stem cells (CSCs) reported in various tumors play a crucial role in tumorigenesis and metastasis of retinoblastoma (Rb). Following the efforts to reduce, replace, and refine the use of mammalian models, we aimed to establish a short-term ...

Digital Three-Dimensional Atlas of Quail Development Using High-Resolution MRI [PDF]

open access: yes, 2007
We present an archetypal set of three-dimensional digital atlases of the quail embryo based on microscopic magnetic resonance imaging (µMRI). The atlases are composed of three modules: (1) images of fixed ex ovo quail, ranging in age from embryonic day 5

MELK-a conserved kinase: functions, signaling, cancer, and controversy. [PDF]

open access: yes, 2015
Maternal embryonic leucine zipper kinase (MELK) is a highly conserved serine/threonine kinase initially found to be expressed in a wide range of early embryonic cellular stages, and as a result has been implicated in embryogenesis and cell cycle control.

Magnetic Resonance Imaging for Characterization of a Chick Embryo Model of Cancer Cell Metastases

open access: yesMolecular Imaging, 2018
Metastasis is the most common cause of death for patients with cancer. To fully understand the steps involved in metastatic dissemination, in vivo models are required, of which murine ones are the most common.

The Alternative Choice of Constitutive Exons throughout Evolution [PDF]

open access: yes, 2007
Alternative cassette exons are known to originate from two processes exonization of intronic sequences and exon shuffling. Herein, we suggest an additional mechanism by which constitutively spliced exons become alternative cassette exons during evolution.

Light Activation of the Phosphoinositide Cycle in Intrinsically Photosensitive Chicken Retinal Ganglion Cells [PDF]

open access: yes, 2010
Purpose: In vertebrates, intrinsically photosensitive retinal ganglion cells (ipRGCs) acting as nonvisual photoreceptors transmit environmental illumination information to the brain, regulating diverse non–image-forming tasks.

Seed-produced anti-globulin VHH-Fc antibodies retrieve globulin precursors in the insoluble fraction and modulate the Arabidopsis thaliana seed subcellular morphology [PDF]

open access: yes, 2020
Key message Nanobody-heavy chain (VHH-Fc) antibody formats have the potential to immunomodulate even highly accumulating proteins and provide a valuable tool to experimentally modulate the subcellular distribution of seed storage proteins.

Female Sex Development and Reproductive Duct Formation Depend on Wnt4a in Zebrafish. [PDF]

open access: yes, 2019
In laboratory strains of zebrafish, sex determination occurs in the absence of a typical sex chromosome and it is not known what regulates the proportion of animals that develop as males or females.

Selenoprotein gene nomenclature [PDF]

open access: yes, 2016
The human genome contains 25 genes coding for selenocysteine-containing proteins (selenoproteins). These proteins are involved in a variety of functions, most notably redox homeostasis.
