Pathways-driven Sparse Regression Identifies Pathways and Genes Associated with High-density Lipoprotein Cholesterol in Two Asian Cohorts [PDF]

arXiv, 2013
Standard approaches to analysing data in genome-wide association studies (GWAS) ignore any potential functional relationships between genetic markers. In contrast gene pathways analysis uses prior information on functional structure within the genome to identify pathways associated with a trait of interest. In a second step, important single nucleotide

Disruption of Vitamin D and Calcium Signaling in Keratinocytes Predisposes to Skin Cancer. [PDF]

, 2016
1,25 dihydroxyvitamin D (1,25(OH)2D), the active metabolite of vitamin D, and calcium regulate epidermal differentiation. 1,25(OH)2D exerts its effects through the vitamin D receptor (VDR), a transcription factor in the nuclear hormone receptor family ...

Sonic Hedgehog Signalling Pathway and Ameloblastoma – A Review

JOURNAL OF CLINICAL AND DIAGNOSTIC RESEARCH, 2015
Ameloblastoma is a benign but aggressive odontogenic neoplasm arising from odontogenic epithelium. Many theories have been proposed to explain the pathogenesis of ameloblatoma. Numerous signalling pathways have been implicated to be associated in the development and progression of this neoplasm.

Decoding regulatory programs underlying placode and dermal condensate cell fate commitment during hair follicle induction via single‐cell multi‐omics analysis

Animal Research and One Health, EarlyView.
The experimental framework of the study encompasses sample collection, single‐cell data analysis, and experimental validation. Abstract Understanding differences in chromatin state and changes in gene regulatory landscape of placode (Pc) and dermal condensate are crucial for decoding hair follicle (HF) morphogenesis programs.

TULP4, a novel E3 ligase gene, participates in neuronal migration as a candidate in schizophrenia

CNS Neuroscience &Therapeutics, EarlyView., 2023
Mutations identified from four SCZ pedigrees resulted in decreased TULP4 expression. Tulp4 knockdown caused delayed neuron migration in embryonic mice, and impaired cognition and prepulse inhibition in adult mice. These phenotypes may be related to TULP4 through its involvement in the formation of a novel E3 ubiquitin ligases.

Complete Conjugacy Invariants of Nonlinearizable Holomorphic Dynamics [PDF]

arXiv, 2009
Perez-Marco proved the existence of non-trivial totally invariant connected compacts called hedgehogs near the fixed point of a nonlinearizable germ of holomorphic diffeomorphism. We show that if two nonlinearisable holomorphic germs with a common indifferent fixed point have a common hedgehog then they must commute.

Genomic characterization of Gli-activator targets in sonic hedgehog-mediated neural patterning [PDF]

, 2007
Sonic hedgehog (Shh) acts as a morphogen to mediate the specification of distinct cell identities in the ventral neural tube through a Gli-mediated (Gli1-3) transcriptional network.

Dynamic Compression Improves Chondrogenesis in the Tissue Engineered Model of Cartilage

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Hyaline cartilage is a dense avascular tissue with low regenerative potential, present at the ends of the diarthrodial joints and in the cartilage growth plate. Skeletal diseases often result from extracellular changes in this tissue; however, studies of these are hindered by the tissue complexity, the difficulty in obtaining human material ...

Hedgehogs of Hausdorff dimension one [PDF]

arXiv, 2009
We present a construction of hedgehogs for holomorphic maps with an indifferent fixed point. We construct, for a family of commuting non-linearisable maps, a common hedgehog of Hausdorff dimension 1, the minimum possible.

The Role of Suppressor of Fused in Development and Tumorigenesis in the Mouse [PDF]

, 2011
Embryonic development is a process that involves a number of evolutionarily wellconserved signaling cascades, including the hedgehog pathway. Mutations in components of this pathway have been identified in certain developmental disorders, and in many ...
