Microscopic Epidermal Identification of \u3cem\u3eYucca\u3c/em\u3e and \u3cem\u3eAgave\u3c/em\u3e for Archaeological Use

, 1992
The microscopic identification of epidermal fragments has been used extensively by wildlife ecologists to determine the diet of various animals. Archaeologists, however, have rarely relied on this simple technique to identify botanical remains observed ...

Identification of mucilage cavity as a significant microscopic characteristic existing in phloem instead of pith of Radix et Rhizoma Rhei

, 2008
The morphologic and microscopic features of Radix et Rhizoma Rhei were studied. The study verified that the mucilage cavities did exist in phloem of rhizomes and roots or abnormal vascular bundles. Also, they were in similar distribution in three species

Heterozygous loss‐of‐function alleles associate the conserved 3′‐5′ exoribonuclease EXOSC10 with hypersensitivity to the anticancer drug 5‐fluorouracil

Molecular Oncology, EarlyView.
EXOSC10, an essential nuclear RNA exosome‐associated 3′‐5′ exoribonuclease, is inhibited by the anticancer drug 5‐fluorouracil (5‐FU), and EXOSC10 depletion increases 5‐FU sensitivity. The colon‐cancer variant EXOSC10S402T, located in a proteolysis motif, is stable and nuclear but nonfunctional in vivo.

Cell‐cycle‐specific lesion evolution rather than inhibition of double‐strand‐break repair underpins cisplatin radiosensitization

Molecular Oncology, EarlyView.
We analyze cisplatin–DNA adducts (CDAs) and double‐strand breaks (DSBs) in a cell‐cycle‐dependent manner. We find that CDAs form similarly across all cell cycle phases. DSBs arise only in S‐phase. CDAs might not directly impair DSB repair, but S‐phase DSB lesions evolve in the presence of CDAs and disrupt repair in G2, also causing radiosensitization ...

A Comparative Analysis of Wood Residues on Experimental Stone Tools and Early Stone Age Artifacts: A Koobi Fora Case Study

, 2002
There have been recently reported plant residues on stone tools from the Okote Member, Koobi Fora, Kenya. No comparative microscopy, however, was available for more specific identification of the residues.

Interaction of HS1BP3 with cortactin modulates TKS5 localisation, cell secretion and cancer malignancy

Molecular Oncology, EarlyView.
Here, we demonstrate that HS1BP3 interacts with Cortactin through a proline‐rich region (PRR3.1) and show that this interaction, and HS1BP3 itself, promote cancer cell proliferation and invasion. Inhibition of this interaction leads to build‐up of TKS5 in multivesicular endosomes and altered secretion of CD63 and CD9, providing an explanation for the ...

Interpreting the effects of DNA polymerase variants at the structural level

Molecular Oncology, EarlyView.
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

A Comparison between Microscopic and Molecular Methods for Identification of Ostreopsis Species in Marine Samples

, 2018
An assessment of O. ovata and O. cf. siamensis presence in some seawater samples and on macro algae was carried out in the Mediterranean Sea. The identification of taxa investigated was performed using traditional microscopic techniques and molecular

Proteasome inhibitor, ixazomib prevents topoisomerase‐I degradation and reverses irinotecan resistance in colorectal cancer

Molecular Oncology, EarlyView.
Ixazomib inhibits proteasome‐mediated degradation of topoisomerase I induced by irinotecan, thereby restoring drug sensitivity and promoting tumor cell death in colorectal cancer. Irinotecan, a topoisomerase I (topoI) inhibitor, is widely used for colorectal cancer, but resistance remains a major clinical challenge.
