Modeling hepatic fibrosis in TP53 knockout iPSC‐derived human liver organoids

open access: yesMolecular Oncology, EarlyView.
This study developed iPSC‐derived human liver organoids with TP53 gene knockout to model human liver fibrosis. These organoids showed elevated myofibroblast activation, early disease markers, and advanced fibrotic hallmarks. The use of profibrotic differentiation medium further amplified the fibrotic signature seen in the organoids.

The Dispersal of Seeds by Birds [PDF]

open access: yesNature, 1888
IT should be borne in mind by readers of NATURE in various parts of the world that many facts bearing on this matter may be collected with very little trouble. At Mr. Thiselton Dyer's suggestion I take this opportunity of supplementing my letter to Mr. Botting Hemsley (NATURE, vol. xxxviii. p. 40).

The signatures of Anthropocene defaunation: cascading effects of the seed dispersal collapse

open access: yesScientific Reports, 2016
Anthropogenic activity is driving population declines and extinctions of large-bodied, fruit-eating animals worldwide. Loss of these frugivores is expected to trigger negative cascading effects on plant populations if remnant species fail to replace the ...

Survivin and Aurora Kinase A control cell fate decisions during mitosis

open access: yesMolecular Oncology, EarlyView.
Aurora A interacts with survivin during mitosis and regulates its centromeric role. Loss of Aurora A activity mislocalises survivin, the CPC and BubR1, leading to disruption of the spindle checkpoint and triggering premature mitotic exit, which we refer to as ‘mitotic slippage’.

Endozoochorus seed dispersal by goats: recovery, germinability and emergence of five Mediterranean shrub species [PDF]

open access: yes, 2013
Herbivores can play an important role as seed dispersal vectors, ungulates constituting potential seed dispersal agents of Mediterranean grasses and shrubs. We evaluated the role of domestic goats as seed dispersers of five representative Mediterranean

Pollination and seed dispersal are the most threatened processes of plant regeneration

open access: yesScientific Reports, 2016
Plant regeneration is essential for maintaining forest biodiversity and ecosystem functioning, which are globally threatened by human disturbance. Here we present the first integrative meta-analysis on how forest disturbance affects multiple ecological ...

Establishment and optimization of the two‐step induction system for generating primordial germ cell‐like cells from chicken embryonic stem cells

open access: yesFEBS Open Bio, EarlyView.
This study optimizes a two‐step induction system to generate PGCLCs from chicken ESCs. The induced cells express germline markers and migrate to gonads in ovo, offering a novel approach for avian genetic resource conservation. Primordial germ cells (PGCs) are the progenitor cells of sperm and eggs.

Owl-mediated diploendozoochorous seed dispersal increases dispersal distance and supports seedling establishment

open access: yesGlobal Ecology and Conservation, 2023
Seed dispersal is an essential process contributing to the maintenance of plant populations. Zoochory is a widespread way of plant dispersal in every terrestrial ecosystem that can ensure the long-distance dispersal of seeds.

Seed type, habitat and time of day influence post-dispersal seed removal in temperate ecosystems [PDF]

open access: yesPeerJ, 2020
Seed survival is of great importance for the performance of plant species and it is strongly affected by post-dispersal seed removal by either different animals such as granivorous species and secondary dispersers or abiotic conditions such as wind or ...
