Summary: Ovarian cancer has a lower incidence rate compared to other gynecological tumor types, but it has the second-highest death rate. CCL2, a multifunctional factor associated with cancer progression, was found to promote proliferation and metastasis of ovarian cancer cells when overexpressed. Knocking down CCL2 inhibited ovarian cancer cell proliferation, migration, and invasion. The study showed that MAP3K19 is the key target through which CCL2 regulates ovarian cancer progression.

Summary: In patients with ovarian cancer, high expression of PAFR affects overall and recurrence-free survival, while rupatadine, an antagonist, effectively inhibits proliferation and migration of ovarian cancer cells.

Summary: The study demonstrated the significance of TLR2 as a biomarker in advanced stage ovarian cancer by showing significantly higher expression levels in women with more advanced OC. This research sheds light on the prognostic potential of TLR2 in developing new diagnostic approaches and increasing survival in confirmed ovarian cancer patients.

Summary: Research suggests that AREG is overexpressed in abdominal fluids of ovarian cancer patients, and its immune modulation is associated with animal survival. The generation of a new antibody to target AREG has extended the survival time of mice.

Summary: Ovarian cancer cells co-cultured with mesenchymal stem cells (MSCs) exhibit increased resistance to platinum-based chemotherapy. However, 2-hydroxyestradiol (2HE2) and dasatinib have been shown to effectively overcome this drug resistance mediated by MSCs. 2HE2 and dasatinib may enhance intracellular platinum concentrations to restore sensitivity of ovarian cancer cells to platinum drugs and limit chemotherapy resistance mediated by the tumor microenvironment.

Summary: In this study, the expression of LAMC2 in PDAC and its regulated network were investigated, with the aim of identifying potential therapies. It was found that LAMC2 was consistently upregulated in PDAC and associated with tumor grade and survival. The LAMC2-regulated network contained downstream effectors shared by the KRAS signaling pathway, and the inhibition of LAMC2 or AXL showed a synergistic antiproliferative effect in combination with MEK1/2 inhibitors in PDAC models.

Summary: The stiffness of the underlying substratum affects Erk signaling dynamics in mammary epithelial cells, soft microenvironments attenuate Erk signaling and alter the amount and spatial distribution of EGF binding at cell membranes. The mechanical microenvironment tunes Erk signaling dynamics via receptor-ligand interactions.

Summary: In this study, the authors investigated the role of AKR1C1/2, a target of the NRF2 pathway, in platinum-resistant epithelial ovarian cancer (EOC). They found that AKR1C1/2 is a key player in the development of chemoresistance and is associated with shorter progression-free survival. Inhibition of AKR1C1/2 and silencing of NRF2 enhanced the therapeutic effect of carboplatin and MPA in vitro. These findings suggest that combination therapy with carboplatin and MPA may be a promising approach for EOC patients.

Summary: Metastasis is the main cause of death in many cancers including colorectal cancer (CRC), but the underlying mechanisms are largely unknown. This study found that the nuclear TYRO3 receptor tyrosine kinase is a strong predictor of poor overall survival in patients with CRC. The function of nuclear TYRO3 in promoting metastasis requires its kinase activity and MMP-2-mediated cleavage, independent of ligand binding. The research also identified BRD3 as one of nuclear TYRO3's substrates and demonstrated that TYRO3-phosphorylated BRD3 regulates genes involved in anti-apoptosis and epithelial-mesenchymal transition.

Summary: The study revealed that miR-338-5p controls epithelial-mesenchymal transition and metastasis of pancreatic cancer cells by targeting the EGFR/ERK pathway, and its expression in clinical analysis is negatively associated with lymph node metastasis and AJCC staging.

Summary: The study reveals that EWI-2 can regulate the distribution of miRNA between cells and exosomes, as well as nuclear translocation of signaling molecules and miRNA through its localization on the nuclear membrane, thus regulating PCa cell metastasis via the EGFR-MAPK-ERK pathway.

Summary: The study demonstrates that KRAS mutation can increase the cleavage of NRG1 from the S-N fusion protein, enhancing various signaling pathways. The coexistence of KRAS mutant and S-N fusion in lung tumors makes them more vulnerable to MEK1/2 and ADAM17 inhibitors.
