Evolution of Ocular Organ‐On‐Chip Systems for Disease Modelling and Drug Testing: Where are We Now?

Advanced Therapeutics, EarlyView.
The rise in ophthalmic diseases due to aging, screen use, and environmental factors has driven demand for better ocular models. Traditional systems fall short, encouraging the development of organ‐on‐chip devices. These microfluidic platforms replicate eye tissue architecture, enable drug screening, and simulate ocular diseases.

Frequent somatic mutations of GNAQ in uveal melanoma and blue naevi. [PDF]

, 2009
BRAF and NRAS are common targets for somatic mutations in benign and malignant neoplasms that arise from melanocytes situated in epithelial structures, and lead to constitutive activation of the mitogen-activated protein (MAP) kinase pathway.

MiR-217 inhibition relieves oxidative stress-induced melanocyte damage by targeting sirtuin 1

Biotechnology & Biotechnological Equipment, 2020
Vitiligo is caused by the disappearance of melanocyte function in the skin, but the mechanism has not been fully elucidated. This study aimed to investigate the expression and role of miR-217 in dysfunctional human primary melanocytes caused by oxidative

Transplantation of Human Melanocytes

Journal of Investigative Dermatology, 1987
Recent advances in the culturing of pigment cells from human beings have made it possible to begin the transplantation of autologous melanocytes into areas of skin that are hypopigmented. In a patient with piebaldism we were able to take pigment cells from a shave biopsy of the normally pigmented skin of the back, expand the cells in culture, and ...

Single‐Cell and Spatial Transcriptomic Profiling of Penile Squamous Cell Carcinoma Reveals Dynamics of Tumor Differentiation and Immune Microenvironment

Advanced Science, EarlyView.
This study uses single‐nucleus RNA sequencing and spatial transcriptomics to investigate penile squamous cell carcinoma (PSCC). It reveals that PSCC tumor cells mimic normal penile epithelium differentiation, independent of HPV status. The Tum_1 subtype shows basal stem‐like characteristics and promotes invasiveness. HPV‐positive basal stem‐like tumors

Origins of the avian neural crest: the role of neural plate-epidermal interactions [PDF]

, 1995
We have investigated the lineage and tissue interactions that result in avian neural crest cell formation from the ectoderm. Presumptive neural plate was grafted adjacent to non-neural ectoderm in whole embryo culture to examine the role of tissue ...

A Variant in a MicroRNA complementary site in the 3' UTR of the KIT oncogene increases risk of acral melanoma. [PDF]

, 2011
MicroRNAs (miRNAs) are small ∼22nt single stranded RNAs that negatively regulate protein expression by binding to partially complementary sequences in the 3' untranslated region (3' UTRs) of target gene messenger RNAs (mRNA).
