From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Arguing Along the Slippery Slope of Human Embryo Research

open access: yes, 1996
One frequent argument in the debate over federal funding of human embryo research is the slippery slope argument. Slope arguments can be of several types: either logical, empirical, or full (a combination of logical and empirical slope arguments, with an

Immunogenicity evaluation of inactivated virus and purified proteins of porcine circovirus type 2 in mice

open access: yesBMC Veterinary Research, 2018
Background Vaccination is considered as an effective and economical way to against PCV2 infection. However, some of commercial available vaccines are based on inactivated viruses, while the others are based on purified protein of PCV2.

Developmental programmes drive cellular plasticity, disease progression and therapy resistance in lung adenocarcinoma

open access: yesMolecular Oncology, EarlyView.
This study shows that lung adenocarcinomas exploit developmental branching morphogenesis to acquire a therapy resistant basal‐like tumour cell state. This process was found to be regulated by combined TP53 loss‐of‐function and type‐I interferon signalling, identifying a novel axis for biomarker and therapeutic target discovery.

Micro-magnetic resonance imaging study of live quail embryos during embryonic development [PDF]

open access: yes, 2011
Eggs containing live Japanese quail embryos were imaged using micro-magnetic resonance imaging (μMRI) at 24-h intervals from Day 0 to 8, the period during which the main body axis is being laid down and organogenesis is taking place.

Embryonic stem cells: modelling effects ofearly embryo environment

open access: yes, 2013
The Developmental Origins of Health and Disease (DOHaD) hypothesis proposes that embryonic environment can induce permanent changes in metabolism during development, increasing the risk of disease in adults. Adverse environments during critical stages of

A novel quinazolinone insulin receptor inhibitor and its synergy with an EGFR inhibitor in glucose‐driven glioblastoma

open access: yesMolecular Oncology, EarlyView.
The novel styrylquinazolinone‐based molecule W1B effectively suppresses glioblastoma by inhibiting IGF1R and EGFR. In high‐glucose microenvironments driving tumor resistance, W1B acts synergistically with the EGFR inhibitor dacomitinib. This combination safely blocks compensatory survival signaling in zebrafish xenograft models. Showcasing promising in

Blood Flow and The Mammalian Embryo [PDF]

open access: yes, 2005
Hemodynamics, or blood fluid dynamics, is of great importance in vascular biology and its role is well recognized in events ranging from atherosclerosis to wound healing.

Birth of India’s first cloned cattle and analysis of its health and reproduction status: A case study

open access: yesScientific Reports
Somatic cell nuclear transfer (SCNT) allows the multiplication of elite livestock and conservation of endangered species. However, restrictions on cow slaughter limit the access to oocytes for SCNT applications in Indian cattle breeds.

Births from aneuploid embryos: where is the evidence?

open access: yesBMJ Connections Clinical Genetics and Genomics
Background Preimplantation genetic testing for aneuploidy (PGT-A) is used principally to identify embryos with whole chromosome aneuploidy, which are generally considered non-viable. Reports of healthy live births following transfer of embryos classified
