Summary: Anti-hormone therapies are ineffective for reducing the incidence of triple negative breast cancer. Visceral obesity is a strong risk factor for this aggressive subtype, and it is unclear how excessive deposition of visceral adipose tissue promotes the malignant transformation. The activation of AhR by factors released from VAT may drive the malignant transformation of breast epithelial cells.

Summary: The mutation of the Drosophila prickle gene causes epileptic seizures and abnormal glial wrapping in insects, suggesting a crucial role of this gene in both neurons and glia. It regulates cell adhesion between neurons and ensheathing glia, ensuring neuron-glial interaction within neuropils. Dysregulation of this process may contribute to PRICKLE1-associated epilepsy.

Summary: Esophageal cancer is a significant global public health problem. Nitrosamines exposure increases the risk of esophageal cancer. This study found that Ribonucleic acid export 1 (RAE1) is upregulated in the early stage of nitrosamine-induced esophageal carcinogenesis and EC tissues. RAE1 plays a role in regulating the cell cycle and proliferation, with its knockdown leading to cell cycle blockade and inhibition of proliferation, while its overexpression has the opposite effect. Additionally, RAE1 regulates lipid metabolism by maintaining the stability of PPAR alpha mRNA.

Summary: VEGF-C secreted by EMT breast cancer cells can promote proliferation, migration, and invasion of epithelial breast cancer cells through non-canonical activation of GLI signaling. Inhibiting VEGF-C in EMT cells or knocking down NRP2 in neighboring epithelial cancer cells disrupts the aggressive phenotypes induced by EMT cells, suggesting a novel therapeutic target for metastasis in breast cancer.

Summary: Membrane receptors are a class of protein-based biocatalysts that are different from enzymes. The luteinizing hormone receptor (LHR), a type of G protein-coupled receptor (GPCR), plays a crucial role in transducing signals from the membrane receptor to the signaling pathways inside living cells. Activation of LHR can be achieved through ligand binding or binding of vanadium compounds, which then activates G proteins and downstream biocatalysts in well-defined signaling pathways. Understanding GPCR-mediated signaling is important for the development of pharmacologically significant compounds, and recent studies have shown that the plasma membrane can serve as an additional target for regulating receptor activity by vanadium compounds.

Summary: The study found that efferocytosis by pleural cavity macrophages through AXL and MERTK receptors led to the production of IL-10, which then influenced dendritic cells to produce TIMP1, thereby facilitating MPE progression. Targeting this inflammatory cascade offers potential therapeutic strategies for MPE.

Summary: Cancer patients often die due to systemic physiological perturbations caused by paraneoplastic syndromes, which can be explored in non-mammalian models. In a Drosophila model, malignant-tumor-produced cytokines activate JAK-STAT signaling, particularly in the cells of the blood-brain barrier, leading to premature death. Inhibiting STAT in the BBB rescues barrier function and extends the lifespan of tumor-bearing hosts, highlighting the importance of BBB alterations in tumor-host interactions and other physiological morbidities.

Summary: This study reveals a previously unknown nuclear role for Dlg in regulating chromatin and transcription by interacting with the nucleosome remodeling factor (NURF) complex. The activity of NURF is essential for the overgrowth of dlg tumors, and this growth suppression is correlated with a reduction in Hippo pathway gene expression, suggesting a new direct mechanism for Dlg in tumor suppression and epithelial polarity regulation.

Summary: The compartmentalized domains of polarized epithelial cells are determined by the antagonistic actions between the Scrib module and the Par complex. Scrib and Dlg proteins in Drosophila limit Lgl phosphorylation at the basolateral cortex, and this 'protection' activity is independent of PP1. The Dlg SH3 domain and the N-terminal region of the HOOK domain play important roles in Lgl protection and recruitment of Scrib to the membrane.

Summary: The shaping of developing organs requires regulation of force and resistance, but how mechanical properties of tissues are monitored is not well understood. In developing Drosophila follicles, a pair of cells called anterior polar cells play a role in monitoring tissue elongation by secreting a matrix metalloproteinase (MMP). This MMP production is regulated by the mechanical properties of the basement membrane, which is sensed through focal adhesion signaling and contractile activity. The polar cells then reciprocally regulate basement membrane remodeling to ensure proper organ shape and reproductive success.

Summary: Malignant tumors can cause complex inflammatory and wound repair responses, leading to defects in blood clotting. A new tumor model in Drosophila shows similarities to coagulopathies observed in patients. The tumor induces hypercoagulation followed by a defective wound healing state. By depleting a tumor-produced clotting factor, survival can be improved in tumor-bearing flies.

Summary: The Review discusses how fly tumors interact with the microenvironment and distant organs to influence disease progression and host physiology. The authors argue that the simplicity of flies and the ability to study lethality in this model provide an opportunity to address why patients ultimately die of cancer.
