Positive autoregulation of ras genes expression in fibroblasts
We have studied the effect of ectopic overexpression of a ras gene on the expression of the other two members of the ras gene family. We obtained NIH3T3 cell lines stably transfected with inducible H-ras and N-ras oncogenes. The expression of these genes

Renin-angiotensin-aldosterone system in ISIAH rats with stressinduced arterial hypertension
Because the renin-angiotensin system (RAS) has a wide range of opportunities in the regulation of fluid and electrolyte balance and arterial pressure, it is currently hypothesized that alterations in systemic circulating or local tissue RAS are some of ...

Optimizing photoactivation of PA‐mCherry for optical pooled CRISPR screens
Photoactivatable PA‐mCherry finds widespread use to optically tag individual cells. However, confocal 405 nm UV laser‐scanning (normal scan) is much less efficient than widefield UV illumination, limiting the use of PA‐mCherry on confocal instruments. We remedy this limitation by reporting that rapid and repeated confocal scanning with a low‐intensity,

Aquaporin‐3 and aquaporin‐5 impact the development of pancreatic ductal adenocarcinoma spheroids
Schematic representation of the role of aquaporin‐3 (AQP3) and aquaporin‐5 (AQP5) in pancreatic ductal adenocarcinoma (PDAC). Both proteins are upregulated in PDAC and are associated with tumor progression and metastatic potential. Silencing AQP3 or AQP5 in PDAC spheroids results in decreased diameter, area, and overall growth, underscoring their key ...

Impeded Nedd4-1-Mediated Ras Degradation Underlies Ras-Driven Tumorigenesis
RAS genes are among the most frequently mutated proto-oncogenes in cancer. However, how Ras stability is regulated remains largely unknown. Here, we report a regulatory loop involving the E3 ligase Nedd4-1, Ras, and PTEN.

Loss of AMBRA1 activates MAPK and angiogenesis signaling pathways in melanoma cells
Loss of AMBRA1 in melanoma cells activates multiple oncogenic pathways associated with tumor progression. Transcriptomic and protein network analyses revealed that AMBRA1 depletion enhances MAPK/ERK signaling, angiogenesis, TGF‐β/EMT signaling, and Wnt/axon guidance pathways.

Gene mutations and expression in breast cancer
Bibliography: leaves 163-190.Breast cancer is the most common cause of death amongst women, with the incidence of the disease varying between countries. Like all other cancers, breast cancer is a multigenic disorder with mutations in oncogenes and tumour

RAS genes encode a family of 21 kDa proteins that are an essential hub for a number of survival, proliferation, differentiation and senescence pathways. Signaling of the RAS-GTPases through the RAF-MEK-ERK pathway, the first identified mitogen-associated
