Women's Experiences With Palliative Care During Pregnancy.

Objective: To explore the experiences of women who received life-limiting fetal diagnoses during pregnancy and support from a perinatal palliative care program.

Design: Descriptive qualitative.

Setting: The perinatal palliative care program is part of a not-for-profit system of 24 hospitals serving the U.

GRHL3 binding and enhancers rearrange as epidermal keratinocytes transition between functional states.

Transcription factor binding, chromatin modifications and large scale chromatin re-organization underlie progressive, irreversible cell lineage commitments and differentiation. We know little, however, about chromatin changes as cells enter transient, reversible states such as migration. Here we demonstrate that when human progenitor keratinocytes either differentiate or migrate they form complements of typical enhancers and super-enhancers that are unique for each state.

Pigment Production Analysis in Human Melanoma Cells.

The human epidermal melanocyte is a highly specialized pigmented cell that serves to protect the epidermis from ultraviolet (UV) damage through the production of melanin, or melanogenesis. Misregulation in melanogenesis leading to either hyper- or hypo-pigmentation is found in human diseases such as malasma and vitiligo. Current therapies for these diseases are largely unsuccessful and the need for new therapies is necessary.

GRHL3/GET1 and trithorax group members collaborate to activate the epidermal progenitor differentiation program.

The antagonistic actions of Polycomb and Trithorax are responsible for proper cell fate determination in mammalian tissues. In the epidermis, a self-renewing epithelium, previous work has shown that release from Polycomb repression only partially explains differentiation gene activation. We now show that Trithorax is also a key regulator of epidermal differentiation, not only through activation of genes repressed by Polycomb in progenitor cells, but also through activation of genes independent of regulation by Polycomb.
