Optimisation of growth conditions for ovine airway epithelial cell differentiation at an air-liquid interface [PDF]

open access: yes, 2018
Respiratory tract infections are of significant concern in the agriculture industry. There is a requirement for the development of well-characterised in vitro epithelial cell culture models in order to dissect the diverse molecular interactions occurring

Retinoic acid's reproducible future [PDF]

open access: yesScience, 2017
Science is facing a reproducibility crisis. In the biomedical sciences, the inability to validate and reproduce findings is slowing progress in understanding basic biological principles. Among the fields hindered by irreproducibility is retinoic acid (RA) research.

Hyperandrogenemia Induces Trophoblast Ferroptosis and Early Pregnancy Loss in Patients With PCOS via CMA‐Dependent FTH1 Degradation

open access: yesAdvanced Science, EarlyView.
In PCOS patients with hyperandrogenemia, decreased ferritin heavy chain 1 (FTH1) causes Fe2⁺ overload and ferroptosis in trophoblasts. Androgens induce FTH1 protein degradation via AR‐LAMP2A‐mediated chaperone‐mediated autophagy pathway, leading to placental development disruption and early pregnancy loss. Metformin mitigates androgen‐induced placental

The ubiquitin ligase HECTD1 promotes retinoic acid signaling required for development of the aortic arch

open access: yesDisease Models & Mechanisms, 2019
The development of the aortic arch is a complex process that involves remodeling of the bilaterally symmetrical pharyngeal arch arteries (PAAs) into the mature asymmetric aortic arch.

A Patient‐Derived Organ‐on‐Chip Platform for Modeling the Tumor Microenvironment and Drug Responses in Pancreatic Cancer

open access: yesAdvanced Science, EarlyView.
Researchers have developed a patient‐derived organ‐on‐a‐chip model for pancreatic cancer by integrating cancer cells with supportive stromal and immune cells inside a microfluidic device. This system mimics the tumor microenvironment, enabling personalized testing of chemotherapy and immunotherapy, and offering new insights into how targeting ...

Retinoic Acid Signaling during Early Spinal Cord Development

open access: yesJournal of Developmental Biology, 2014
Retinoic acid signaling is required at several steps during the development of the spinal cord, from the specification of generic properties to the final acquisition of neuronal subtype identities, including its role in trunk neural crest development ...

Parabiosis, Assembloids, Organoids (PAO)

open access: yesAdvanced Science, EarlyView.
This review evaluates parabiosis, organoids, and assembloids as complementary disease models spanning systemic, organ, and multi‐organ levels. It highlights their construction strategies, applications, and current limitations, while emphasizing their integration with frontier technologies such as artificial intelligence, organ‐on‐a‐chip, CRISPR, and ...

Effects of all Trans Retinoic Acid Combined with Cisplatin on Survival of Gastric Cancer Cell Line (AGS)

open access: yesپزشکی بالینی ابن سینا, 2013
Introduction & Objective: All-trans retinoic acid, a derivative of retinoids, is widely used to in-duce prolifferation, differentiation and apoptosis in normal, precancareous and cancerous cells. Cisplatin, an effective drug for cancer treatment, induces

Extracellular Vesicles of Streptococcus anginosus Mediate Gastritis via Epithelial Barrier Disruption and Macrophage‐driven Inflammation

open access: yesAdvanced Science, EarlyView.
Streptococcus anginosus extracellular vesicles (SA‐EVs) accumulate in gastric tissue, disrupt epithelial tight junctions, and induce gastritis characterized by neutrophil infiltration and elevated cytokines (TNF‐α, IL‐6, IL‐17A). Proteomics identifies TMPC and FBP62 as key SA‐EVs virulence factors; their genetic deletion attenuates inflammation ...
