The protein predicted by the sequence of the human pim-1 proto-oncogene shares extensive homology with known serine/threonine protein kinases, and yet the human Pim-1 enzyme has previously been reported to exhibit protein tyrosine kinase activity both in vitro and in vivo. Recently a new class of protein kinases has been identified which exhibits both protein-serine/threonine and protein-tyrosi...

Processing in memory (PIM) implemented via 3D die stacking has been recently proposed to reduce the widening gap between processor and memory performance. By moving computation that demands high memory bandwidth to the base logic die of a 3D memory stack, PIM promises significant improvements in energy efficiency. However, the vision of PIM implemented via 3D die stacking could potentially be d...

It is well documented that Provirus integration site for Moloney murine leukemia virus 1 (Pim-1), as a proto-oncogene encoding a serine/threonine kinase with multiple cellular functions, is tightly associated with the occurrence and development of tumors. Overexpression of Pim-1 plays a critical role in the progression of several different tumors. In this study, esophageal squamous cell carcino...

As artificial intelligence becomes a pervasive tool for the billions of IoT (Internet things) devices at edge, data movement bottleneck imposes severe limitations on performance and autonomy these systems. PiM (processing-in-memory) is emerging as way mitigating while satisfying stringent performance, energy efficiency, accuracy requirements edge imaging applications that rely CNNs (convolution...

The proviral insertion in murine (PIM) lymphoma proteins are a serine/threonine kinase family composed of three isoformes: Pim-1, Pim-2 and Pim-3. They play a critical role in the control of cell proliferation, survival, homing and migration. Recently, overexpression of Pim kinases has been reported in human tumors, mainly in hematologic malignancies. In vitro and in vivo studies have confirmed...

RATIONALE The senescent cardiac phenotype is accompanied by changes in mitochondrial function and biogenesis causing impairment in energy provision. The relationship between myocardial senescence and Pim kinases deserves attention because Pim-1 kinase is cardioprotective, in part, by preservation of mitochondrial integrity. Study of the pathological effects resulting from genetic deletion of al...

BACKGROUND AND METHODS Pim family proteins are oncogenic kinases implicated in several types of cancer and involved in regulation of cell proliferation, survival as well as motility. Here we have investigated the ability of Pim kinases to promote metastatic growth of prostate cancer cells in two xenograft models for human prostate cancer. We have also evaluated the efficacy of Pim-selective inh...

BACKGROUND Pim-3 kinase is a highly homologous serine/threonine kinase that is overexpressed in hematological malignancies and solid tumors. Few studies have been conducted to define the role of Pim-3 in solid tumors, especially in prostate cancer. The aim of this study was to define the role of Pim-3 in development and prognosis of prostate cancer. MATERIAL AND METHODS We collected specimens f...

The Akt kinases promote hematopoietic cell growth and accumulation through phosphorylation of apoptotic effectors and stimulation of mTOR-dependent translation. In Akt-transformed leukemic cells, tumor growth can be inhibited by the mTOR inhibitor rapamycin, and clinical trials of rapamycin analogs for the treatment of leukemia are under way. Surprisingly, nontransformed hematopoietic cells can...

We previously showed that the 44-kDa serine/threonine kinase Pim-1 (Pim-1L) can protect prostate cancer cells from apoptosis induced by chemotherapeutic drugs (Xie, Y., Xu, K., Dai, B., Guo, Z., Jiang, T., Chen, H., and Qiu, Y. (2006) Oncogene 25, 70-78). To further explore the mechanisms of Pim-1L-mediated resistance to chemotherapeutic drugs in prostate cancer cells, we employed a yeast two-h...
