Long-term cargo tracking reveals intricate trafficking through active cytoskeletal networks in the crowded cellular environment

open access: yesNature Communications, 2023
A eukaryotic cell is a microscopic world within which efficient material transport is essential. Yet, how a cell manages to deliver cellular cargos efficiently in a crowded environment remains poorly understood.

Multichannel spectroscopy guide [PDF]

open access: yes, 1969
System makes use of diverging duct walls for conducting the light from entrance slips to the conductors by means of multiple reflectors. This system simultaneously records, photoelectrically, the intensities of several closely spaceed narrow wavelengths ...

Reflectance Spectroscopy [PDF]

open access: yesGastrointestinal Endoscopy Clinics of North America, 2009
Reflectance spectroscopy is an emerging technology which provides rapid and safe evaluation of tissue for dysplasia and ischemia. The probe-based devices can be passed through most endoscopes. Current applications include detection of dysplasia in Barrett's esophagus, colitis, and colon polyps.

The neural crest‐associated gene ERRFI1 is involved in melanoma progression and resistance toward targeted therapy

open access: yesMolecular Oncology, EarlyView.
ERRFI1, a neural crest (NC)‐associated gene, was upregulated in melanoma and negatively correlated with the expression of melanocytic differentiation markers and the susceptibility of melanoma cells toward BRAF inhibitors (BRAFi). Knocking down ERRFI1 significantly increased the sensitivity of melanoma cells to BRAFi.

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

open access: yesMolecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

open access: yesMolecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

Formation of the β-barrel assembly machinery complex in lipid bilayers as seen by solid-state NMR

open access: yesNature Communications, 2018
The β-barrel assembly machinery (BAM) catalyzes β-barrel protein insertion into the outer membrane of E.coli. Here authors employ high-sensitivity solid-state NMR to reveal how the lipid environment and formation of the BamA-BamCDE complex affect BamA ...

α-catenin switches between a slip and an asymmetric catch bond with F-actin to cooperatively regulate cell junction fluidity

open access: yesNature Communications, 2022
By using laser tweezers, the authors show that a single α-catenin molecule does not resist force on F-actin. However, clustering of multiple molecules and force applied toward F-actin pointed end engage a molecular switch in α-catenin, which unfolds and ...

Relic Neutrino Absorption Spectroscopy [PDF]

open access: yes, 2004
Resonant annihilation of extremely high-energy cosmic neutrinos on big-bang relic anti-neutrinos (and vice versa) into Z-bosons leads to sizable absorption dips in the neutrino flux to be observed at Earth.
