The Embryonic Development of the Cotylean Polyclad Phrikoceros jannetae

open access: yesActa Zoologica, EarlyView.
ABSTRACT Polyclads exhibit distinct developmental modes ranging from direct to indirect development, with several transitional stages also recognised. The existence of an indirect developmental mode in polyclads with a planktonic life history stage in the form of a free‐swimming larva is unique among all free‐living flatworms and makes polyclads a ...

Relationship Between PTBP1 and Pancreatic Cancer Based on microRNA and Behavior During TYMS‐Mediated Carcinogenesis

open access: yesCancer Science, EarlyView.
Corresponding Author and colleagues identify a pancreas‐enriched microRNA, miR‐216b‐5p, that suppresses PTBP1 and its downstream effector TYMS. Their findings reveal a novel miR‐216b‐5p/PTBP1/TYMS regulatory axis driving pancreatic cancer progression and establish PTBP1 as a central molecular regulator of tumor biology beyond its metabolic role ...

Monitoring wildlife health for diseases with visible signs by integrating camera traps with marked individuals

open access: yesConservation Biology, EarlyView.
Abstract Monitoring wildlife health is essential for conservation and management, wildlife and livestock welfare, and public health in a One Health framework. Yet, wildlife health monitoring often requires long‐term fieldwork and intensive sampling, which can be costly or logistically challenging, especially for remote, rare, or elusive populations. To

Shikimate pathway disruption in yeast induces metabolite self‐assembly into toxic aggregates

open access: yesThe FEBS Journal, EarlyView.
In Saccharomyces cerevisiae, shikimate pathway disruption induces toxic metabolite assemblies. Deleting ARO4 plus phenylalanine (Phe) feeding causes Phenylalanine accumulation, lowers ARO3 activity, and triggers amyloid‐like fibril formation. Deleting ARO3 plus tyrosine (Tyr) feeding leads to Tyrosine buildup and similar fibril assembly.

H2‐dependent modulation of tetrahydromethanopterin S‐methyltransferase (Mtr complex) activity by the small protein MtrR in Methanosarcina mazei

open access: yesThe FEBS Journal, EarlyView.
Small protein MtrR is a regulator of the Mtr methyltransferase complex in Methanosarcina mazei. It binds specifically to the MtrA subunit and modulates Mtr activity in response to hydrogen (H2) availability. Deleting mtrR impairs growth in the presence but not absence of H2, indicating its role in directing methyl transfer toward an energy‐conserving ...
