Residual Level of Chlorpyrifos in Lettuces Grown on Chlorpyrifos-Treated Soils

open access: yesApplied Sciences, 2018
This study was conducted to investigate the residual loss of chlorpyrifos and the amount transferred to lettuce from soil. Field trials on lettuce were conducted in two different greenhouses located in Yongin (field 1) and Gwangju (field 2) in Korea ...

Adaptation through Translocation [PDF]

open access: yesNeuron, 2002
Papers by and, in this issue of Neuron, describe how massive and rapid translocation of specific elements of the phototransduction cascades in different phyla, namely, the G protein (transducin) in vertebrate rods and light-sensitive TRPL channels in the microvillar rhabdomeres of Drosophila, contribute to photoreceptor adaptation.

Small modifier, big decision: switching to SUMO mode adds weight to cancer stemness in mammary tumors

open access: yesMolecular Oncology, EarlyView.
Inhibition of protein SUMOylation has been shown to block tumorigenesis; however, the specific mechanisms by which SUMOylation controls the tumor‐initiating capacities remain elusive. Li et al. describe the role of Etv1 SUMOylation in cancer stem cells using mouse models of mammary gland tumorigenesis.

Ethics of Assisted Evolution in Marine Conservation

open access: yesFrontiers in Marine Science, 2019
Climate change is outpacing existing rates of evolution and adaptation for many marine organisms. Human societies are pushing hard to find new solutions to save and protect marine ecosystems, generating research on manipulating genetics of wild organisms

Proton Translocation in Proteins

open access: yesAnnual Review of Physical Chemistry, 1989
The active transport of protons across the low dielectric barrier imposed by biological membranes is accomplished by a plethora of proteins that span the ca. 40 A of the phospholipid bilayer. The free energy derived from the proton electrochemical potential established by the translocation of these protons can subsequently be used to drive vital ...

METTL3 knockout accelerates hepatocarcinogenesis via inhibiting endoplasmic reticulum stress response

open access: yesFEBS Open Bio, Volume 15, Issue 7, Page 1144-1158, July 2025.
Liver‐specific knockout of N6‐methyladenosine (m6A) methyltransferase METTL3 significantly accelerated hepatic tumor initiation under various oncogenic challenges, contrary to the previously reported oncogenic role of METTL3 in liver cancer cell lines or xenograft models. Mechanistically, METTL3 deficiency reduced m6A deposition on Manf transcripts and

Translocation arrest by reversible folding of a precursor protein imported into mitochondria [PDF]

open access: yes, 1989
Passage of precursor proteins through translocation contact sites of mitochondria was investigated by studying the import of a fusion protein consisting of the NH2-terminal 167 amino acids of yeast cytochrome b2 precursor and the complete mouse ...

Human-crocodile conflict and conservation implications of Saltwater Crocodiles Crocodylus porosus (Reptilia: Crocodylia: Crocodylidae) in Sri Lanka

open access: yesJournal of Threatened Taxa, 2015
Human-wildlife conflict occurs when human requirements encroach on those of wildlife populations, with potential costs to both humans and wild animals.  As top predators in most inland waters, crocodilians are involved in human-wildlife conflicts in many
