The role of sphingosine-1-phosphate in inflammation and cancer progression

Sphingosine-1-phosphate (S1P) is a pleiotropic lipid mediator that regulates cell survival and migration, immune cell recruitment, angiogenesis and lymphangiogenesis. Cancer cells produce elevated levels of S1P, contributing to the tumor microenvironment and linking cancer and inflammation. Considering the critical role of S1P in linking inflammation and cancer, it is possible that the S1P signaling pathway could be a novel therapeutic target for cancers with chronic inflammation.

Mitochondrial network structure homeostasis and cell death

Here, we examine the relevance of the homeostasis of the mitochondrial network structure in 3 different types of cell death, including autophagy, apoptosis and necroptosis. Furthermore, a variety of cancers often exhibit a fragmented mitochondrial phenotype. Targeting the mitochondrial fission protein Drp1or other shaping proteins is becoming a topic of interest. Further studies are needed to understand the differential effects of oncogenic signaling pathways on mitochondrial dynamics and to identify additional new signaling axes that regulate mitochondrial network structure homeostasis.

Langerhans cell histiocytosis in adults: Advances in pathophysiology and treatment

Recent studies have shown that Langerhans cell histiocytosis (LCH) is a clonally expanding myeloid neoplasm. Although LCH is not always fatal, delayed diagnosis or treatment can result in serious impairment of organ function and decreased quality of life. This study summarizes recent advances in the pathophysiology and treatment of adult LCH, to raise awareness of this “orphan disease”.

Long non-coding RNA MIF-AS1 promotes gastric cancer cell proliferation and reduces apoptosis to upregulate NDUFA4

Our findings showed that lncMIF-AS1 is involved in gastric cancer tumorigenesis as a tumor activator gene. Through upregulation of NDUFA4, lncMIF-AS1 promotes gastric cancer cell proliferation and repressed apoptosis. Moreover, we showed that lncMIF-AS1 activates NDUFA4 expression by sponging to miR-212-5p in gastric cancer cells. And inhibition of lnvMIF-AS1/miR-212-5p/NDUFA4 may provide an attractive therapeutic target for the treatment of gastric cancer.

Phosphorylation of serine/arginine-rich splicing factor 1 at tyrosine 19 promotes cell proliferation in pediatric acute lymphoblastic leukemia

Our results underscore the phosphorylation of serine/arginine-rich splicing factor 1 (SRSF1) at the tyrosine 19 (Tyr-19) residue disrupts subcellular localization of SRSF1 and promotes cell proliferation in leukemic cells by accelerating cell-cycle progression. This study undoubtedly adds a new layer in understanding of how the posttranslational mechanism supports leukemia progression. Inhibitors targeting Tie2 kinase that could catalyze Tyr-19 phosphorylation of SRSF1 offer a promising therapeutic target for the treatment of pediatric ALL.

Chemokine (C-X-C motif) ligand 1 and CXCL2 produced by tumor promote the generation of monocytic myeloid-derived suppressor cells

Our results elucidated that CXCL1 and CXCL2, which were originally characterized as chemokines of neutrophils, specifically promoted the expansion of mo-MDSC, a subtype of MDSC, in the presence of GM-CSF. Moreover, we found that, in addition to the tumor cells, tumor-infiltrated CD11b+ myeloid cells also expressed CXCL1 and CXCL2. Therefore, inhibition of CXCL1 and CXCL2 could decrease mo-MDSC generation and improve host immunosurveillance.

Transduced caudal-type homeobox (CDX) 2/CDX1 can induce growth inhibition on CDX-deficient gastric cancer by rapid intestinal differentiation

Exogenous expression of CDX2/CDX1 can lead to G0-G1 growth arrest in CDX-deficient gastric cancer cells, accompanied by induction of intestinal genes and decreased expression of gastric genes. Publicly available databases and hierarchical clustering of gastric tissue showed that gastric cancer with CDX expression has significantly better clinical outcomes. A novel therapy against gastric cancer based on induced intestinal differentiation may be possible in the future.

FBXW7 modulates malignant potential and cisplatin-induced apoptosis in cholangiocarcinoma through NOTCH1 and MCL1

The ubiquitin ligase FBXW7 is associated with prognostic outcome in cholangiocarcinoma patients. FBXW7 was found to regulate the migration and self-renewal of cholangiocarcinoma cells through modulation of NOTCH1 as well as CDDP-induced apoptosis through MCL1 accumulation for the first time in cholangiocarcinoma cells. These findings suggest that FBXW7 modulates the malignant potential of cholangiocarcinoma through two signals, NOTCH1 and MCL1.

Primary breast diffuse large B-cell lymphoma in the rituximab era: Therapeutic strategies and patterns of failure

Primary breast diffuse large B-cell lymphoma (PB-DLBCL) has a continuous pattern of relapse, especially with frequent late relapses in the central nervous system (CNS) and contralateral breast. Rituximab and radiotherapy confer complementary benefit in the reduction of relapse. However, neither the addition of rituximab nor prophylactic intrathecal chemotherapy could effectively prevent CNS relapse for PB-DLBCL patients.

RK-287107, a potent and specific tankyrase inhibitor, blocks colorectal cancer cell growth in a preclinical model

Aberrant activation of Wnt/β-catenin signaling causes tumorigenesis and promotes the proliferation of colorectal cancer cells. We report a novel tankyrase-specific PARP inhibitor RK-287107, which inhibits tankyrase-mediated PARylation of Axin and downregulates β-catenin signaling in APC-mutated colorectal cancer cells. RK-287107 exerts a proof-of-concept antitumor effect in vivo, and thus may have potential for cancer therapy.
