A review and perspective paper: Ras oncogene gets modest, from kingpin to mere henchman.

The concomitant activation of both the YAP1 co-transcription factor and RAS GTPases is a hallmark of several aggressive cancers, though the intricacies of their relationship and implications for oncogenesis are still poorly understood. This review has presented a cooperative model where YAP1 and RAS are not independently acting oncogenes but rather interdependently acting ones, with each fulfilling an essential role within the oncogenic process. YAP1 is responsible for initiating the expression of key proteins that contribute to various cancer traits.

Assessing personalized responses to anti-PD-1 treatment using patient-derived lung tumor-on-chip.

There is a compelling need for approaches to predict the efficacy of immunotherapy drugs. Tumor-on-chip technology exploits microfluidics to generate 3D cell co-cultures embedded in hydrogels that recapitulate simplified tumor ecosystems. Here, we present the development and validation of lung tumor-on-chip platforms to quickly and precisely measure ex vivo the effects of immune checkpoint inhibitors on T cell-mediated cancer cell death by exploiting the power of live imaging and advanced image analysis algorithms.

YAP/TEAD involvement in resistance to paclitaxel chemotherapy in lung cancer.

The Yes-associated protein (YAP) oncoprotein has been linked to both metastases and resistance to targeted therapy of lung cancer cells. We aimed to investigate the effect of YAP pharmacological inhibition, using YAP/TEA domain (TEAD) transcription factor interaction inhibitors in chemo-resistant lung cancer cells. YAP subcellular localization, as a readout for YAP activation, cell migration, and TEAD transcription factor functional transcriptional activity were investigated in cancer cell lines with up-regulated YAP, with and without YAP/TEAD interaction inhibitors.

WWOX binds MERIT40 and modulates its function in homologous recombination, implications in breast cancer.

The tumor suppressor gene WWOX is localized in an unstable chromosomal region and its expression is decreased or absent in several types of cancer. A low expression of WWOX is associated with a poor prognosis in breast cancer (BC). It has recently been shown that WWOX contributes to genome stability through its role in the DNA damage response (DDR).

Autophagy Is Polarized toward Cell Front during Migration and Spatially Perturbed by Oncogenic Ras.

Autophagy is a physiological degradation process that removes unnecessary or dysfunctional components of cells. It is important for normal cellular homeostasis and as a response to a variety of stresses, such as nutrient deprivation. Defects in autophagy have been linked to numerous human diseases, including cancers.
