Liver X Receptor α (LXRα) Regulates 5β‐Reductase (AKR1D1) Expression in Avian Embryos: Implications for Yolk Steroid Metabolism

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 345, Issue 5, Page 456-461, June 2026.
ABSTRACT Steroid‐mediated maternal effects are well‐studied as a source of phenotypic variation. In bird eggs, the yolk contains various steroids that can influence embryonic development. However, one complicating factor in understanding how yolk steroids affect development is that the embryo metabolizes yolk steroids to regulate exposure.

ParaHox Genes Revisited: From Gut Patterning to Integrated Axial and Neural Organization in Rotifera

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, Volume 346, Issue 4, Page 357-369, June 2026.
In rotifers, ParaHox genes show a dispersed genomic organization, with Xlox absent across gnathiferans. Exclusive neuronal expression of Gsx and Cdx reveals that ancestral ParaHox genes coordinated neural and epithelial development beyond gut patterning, suggesting an integrated role in early bilaterian body plan organization.

From cells to reefs—fluorescent protein distribution reveals species‐specific photoadaptation in closely related Caribbean corals

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Fluorescent proteins (FPs) are diverse and widespread pigments in reef‐building corals, assumed to modulate the internal light microenvironment within coral tissues. Yet, their precise distribution and organization at the tissue and cellular levels remain poorly understood, limiting our understanding of their functional roles.

The Role of N6‐Methyladenosine Modification in Health and Disease

MedComm, Volume 7, Issue 6, June 2026.
N6‐methyladenosine (m6A) is the most prevalent internal RNA modification in eukaryotes, acting as a pivotal epitranscriptomic regulator of RNA metabolism. This modification plays a dual role: it maintains physiological homeostasis under normal conditions but drives disease progression when dysregulated.

Organoids: From Bench to Bedside Applications

MedComm, Volume 7, Issue 6, June 2026.
Organoids, as a groundbreaking biomedical research platform, utilize adult stem cells (ASCs), embryonic stem cells (ESCs), and induced pluripotent stem cells (iPSCs) as sources. By integrating specific growth and differentiation signals within an extracellular matrix (e.g., Matrigel), organoids guide cells to self‐assemble into three‐dimensional ...
