PTBP1‐Mediated Alternative Splicing of DNAJB6 Promotes Everolimus Resistance in Clear Cell Renal Cell Carcinoma via EIF4B/PKIB/AKT/mTOR Positive Feedback Loop

open access: yesAdvanced Science, EarlyView.
PTBP1‐mediated alternative splicing drives a pathogenic switch to the DNAJB6b isoform in everolimus‐resistant clear cell renal cell carcinoma. This splicing event programs a positive feedback loop including EIF4B/PKIB/AKT/mTOR, promoting aggressive therapy resistance.

Detaching Photosensitive Nanoparticles from Cells Prevents Them from Remaining in Cells after Photoporation

open access: yesAdvanced Science, EarlyView.
Phenylboronic acid‐functionalized gold nanoparticles reversibly attach to cell‐surface glycans, enhancing photoporation‐mediated intracellular delivery. After irradiation, ATP competitively disrupts the boronic ester interactions and removes cell‐associated nanoparticles, markedly reducing residual gold.

Strontium-90 in Man

Science, 1957
The world-wide average strontium-90 content of man was about 0.12 micromicrocurie per gram of calcium (1/10,000 of the maximum permissible concentration) in the fall of 1955. A few values as high as 10 times the average have been obtained. This value is in accord with the predicted value based on fallout measurements and fractionation through
