Smad ubiquitin regulatory factors (SMURFS) belong to the HECT- family of E3 ubiquitin ligases. This family has two members, SMURF1 and SMURF2. SMURFs have emerged as well studied negative regulators of TGF induced intracellular signaling. However, increasingly it is being realized that SMURFs tactfully modulate an array of proteins in different cancers. This review sets spotlight on how SMURF1 and SMURF2 communicate with effectors of different signaling pathways during the multistep progression to cancer. We also summarize how microRNAs (miRNAs) effectively control SMURFs in different cancers. Role of SMURFs is context dependent in . . .different cancers and better concepts related to miRNA regulation of SMURFs in different stages and steps of cancer will be helpful in efficient translation of laboratory findings to clinic. © 2016 by the C.M.B.

Interdisciplinary research has revolutionized the field of medicine and we have witnessed exponential increase in the high-impact research in past few decades. However, the road to this burgeoning research field is obstacle-ridden because of intratumor heterogeneity, loss of apoptosis and dysregulation of spatio-temporally controlled signaling pathways. Ground-breaking findings obtained through genetic, genomic and proteomic studies have considerably improved our concepts related to the complexity of protein network and excitingly, discovery of miRNAs has added another layer of intricacy to quantitatively regulated gene networks. In . . . this review, we chronicle the milestone achievements and discuss how Pterostilbenes effectively regulated different cellular pathways. We have provided detailed mechanistic insights related to regulation of JAK-STAT signaling, Notch pathway, Wnt mediated intracellular signaling by pterostilbene. Underlying mechanisms about regulation of PI3K/AKT and MAPK pathways by pterostilbene in different cancers. Regulation of Metastasis-associated protein 1 (MTA1) proteins and Human telomerase reverse transcriptase (hTERT) in cancer cells by pterostilbene. Pterostilbene has also been reported to modulate the expression of various oncogenic and tumor suppressor microRNAs in cancer cells. Better and sharper comprehension of the concepts associated with the modes of action of pterostilbene in different cancers will be useful in identification of cancers which can be efficiently targeted by pterostilbene. © 2017 by the C.M.B.

Massively parallel sequencing, genomic and proteomic technologies have provided near complete resolution of signaling landscape of breast cancer (BCa). NEDD4 family of E3-ubiquitin ligases comprises a large family of proteins particularly, SMURFs (SMURF1, SMURF2), WWPs and NEDD4 which are ideal candidates for targeted therapy. However, it is becoming progressively more understandable that SMURFs and NEDD4 have “split-personalities”. These molecules behave dualistically in breast cancer and future studies must converge on detailed identification of context specific role of these proteins in BCa. Finally, we provide scattered clues of . . . regulation of SMURF2 by oncogenic miRNAs, specifically considering longstanding questions related to regulation of SMURF1 and WWPs by miRNAs in BCa. SMURFS, WWPs and NEDD4 are versatile regulators and represent a fast-growing field in cancer research and better understanding of the underlying mechanisms will be helpful in transition of our knowledge from a segmented view to a more conceptual continuum. © 2019, Springer Nature Switzerland AG
