Analysis of Gene Expression in Aedes aegypti Suggests Changes in Early Genetic Control of Mosquito Development

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
ABSTRACT Aedes aegypti, a critical vector for tropical diseases, poses significant challenges for studying its embryogenesis due to difficulties in removing its rigid chorion and achieving effective fixation for in situ hybridization. Here, we present novel methodologies for fixation, dechorionation, DAPI staining, and in situ hybridization, enabling ...

Formation of a “Pre-mouth Array” from the Extreme Anterior Domain Is Directed by Neural Crest and Wnt/PCP Signaling

open access: yesCell Reports, 2016
The mouth arises from the extreme anterior domain (EAD), a region where the ectoderm and endoderm are directly juxtaposed. Here, we identify a “pre-mouth array” in Xenopus that forms soon after the cranial neural crest has migrated to lie on either side ...

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

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
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.

Expanding the genotypic spectrum of PCSK1 deficiency: A novel mutation in severe neonatal diarrhea

open access: yesJPGN Reports, EarlyView.
Abstract Among congenital diarrhea and enteropathies (CODEs), proprotein convertase subtilisin/kexin type 1 (PCSK1) deficiency is a rare monogenic disorder, associated with severe neonatal diarrhea and polyendocrinopathies. We report an 18‐day‐old male neonate, born to consanguineous parents, presenting with persistent watery diarrhea, metabolic ...

The safe and effective use of tofacitinib and ustekinumab combination therapy in infantile onset inflammatory bowel disease

open access: yesJPGN Reports, EarlyView.
Abstract Infantile‐onset inflammatory bowel disease (IOIBD) is a rare and severe subset of very‐early‐onset IBD, often associated with immune dysregulation and poor response to conventional therapies. Data regarding the use of Janus kinase inhibitors (JAKI) in this population is limited.

mRNA and miRNA expression profiles in an ectoderm-biased substate of human pluripotent stem cells

open access: yesScientific Reports, 2019
The potential applications of human pluripotent stem cells, embryonic stem (ES) cells, and induced pluripotent stem (iPS) cells in cell therapy and regenerative medicine have been widely studied.

Airway Involvement in Conradi–Hünermann–Happle Syndrome: A Novel Clinical Manifestation

open access: yesThe Laryngoscope, EarlyView.
We report the first documented case of airway involvement in Conradi–Hünermann–Happle syndrome (CDPX2), an X‐linked dominant form of chondrodysplasia punctata caused by pathogenic variants in EBP. A 2‐month‐old female with genetically confirmed CDPX2 developed severe subglottic stenosis and persistent respiratory distress requiring CPAP; cross ...

Endoscopic‐Assisted Transcervical Excision of Second Branchial Cleft Anomalies in Young Children

open access: yesThe Laryngoscope, EarlyView.
We describe an endoscopic‐assisted transcervical technique for excision of second branchial cleft anomalies in young children. In three cases (ages 2–8), this approach allowed safe identification and ligation of the tracts while providing improved visualization and allowing smaller incisions.

Mechanical plasticity of cell membranes enhances epithelial wound closure

open access: yesPhysical Review Research
During epithelial wound healing, cell morphology near the healed wound and the healing rate vary strongly among different developmental stages even for a single species like Drosophila.
