Cancer-associated fibroblasts in gynecological malignancies: are they really allies of the enemy?

Abstract

Molecular and cellular components of the tumor microenvironment are essential for cancer progression. The cellular element comprises cancer cells and heterogeneous populations of non-cancer cells that satisfy tumor needs. Immune, vascular, and mesenchymal cells provide the necessary factors to feed the tumor mass, promote its development, and favor the spread of cancer cells from the primary site to adjacent and distant anatomical sites. Cancer-associated fibroblasts (CAFs) are mesenchymal cells that promote carcinogenesis and progression of various malignant neoplasms. CAFs act through the secretion of metalloproteinases, growth factors, cytokines, mitochondrial DNA, and non-coding RNAs, among other molecules. Over the last few years, the evidence on the leading role of CAFs in gynecological cancers has notably increased, placing them as the cornerstone of neoplastic processes. In this review, the recently reported findings regarding the promoting role that CAFs play in gynecological cancers, their potential use as therapeutic targets, and the new evidence suggesting that they could act as tumor suppressors are analyzed and discussed.

Kinase activities in pancreatic ductal adenocarcinoma with prognostic and therapeutic avenues

“…Moreover, activated INSR/IGF1R and JAK kinases in Phos3 could be associated with EMT and cancer stemness [98], as well as the immunosuppression [99]. HIPK1 in this subtype could be involved in CAF differentiation and invasion [100,101]. Altogether, Phos3 recapitulated kinase activities that may play a role in the interaction with the tumor microenvironment and may serve to design better therapeutic regimes and tackle the stromal barrier.…”
