mTORC1 is aberrantly activated in renal cell carcinoma (RCC) and is targeted by rapalogs. As for other targeted therapies, rapalogs clinical utility is limited by the development of resistance. Resistance often results from target mutation, but mTOR mutations are rarely found in RCC.

Article Synopsis
  • Photothermal therapy (PTT) is a new and effective way to treat cancer that uses special nanomaterials to target and kill cancer cells, including those resistant to other treatments.
  • In experiments with mice and cancer cells, researchers found that the right amount of PTT can help mice live longer and can disrupt the cancer cells' survival mechanisms.
  • The study discovered that PTT triggers important changes in the cells that can lead to cancer cell death, showing promise for PTT as a potential treatment for tough-to-treat cancers.

Substantial number of breast cancer (BC) patients undergoing radiation therapy (RT) develop local recurrence over time. During RT therapy, cells can gradually acquire resistance implying adaptive radioresistance. Here we probe the mechanisms underlying this acquired resistance by first establishing radioresistant lines using ZR-75-1 and MCF-7 BC cells through repeated exposure to sub-lethal fractionated dose of 2Gy up to 15 fractions.

The epithelial cell adhesion molecule (EpCAM) is a transmembrane cell adhesion glycoprotein, which primarily contributes to stemness, proliferation, and metastasis properties of tumor cells. Regulated intramembrane proteolysis by ADAM proteases and γ-secretase cleaves EpCAM into an ∼27 kDa soluble extracellular and an ∼4 kDa cytoplasmic domain (EpICD). After the EpICD fragment is released inside the cell, the formation of a nuclear signaling complex with the FHL2 molecule is critical for exerting its regulatory role.

Conventional therapy regimens for pancreatic cancer (PC) are surgical resection and systemic gemcitabine based chemotherapy. Recent studies showed that curcumin could potentiate the anticancer effect of gemcitabine in PC. However, due to its poor water solubility, effective bioavailability of curcumin is insufficient, resulting in poor efficacy.

Genetic reporter systems provide a good alternative to monitor cellular functions in vitro and in vivo and are contributing immensely in experimental research. Reporters like fluorescence and bioluminescence genes, which support optical measurements, provide exquisite sensitivity to the assay systems. In recent years several activatable strategies have been developed, which can relay specialized molecular functions from inside the cells.
