Getting sticky with it: Phospholipid found to play a key role in epithelial cell adhesion

Researchers found phosphatidylinositol bisphosphate (PIP2) essential for epithelial cell-cell adhesion and maintaining cellular identity. PIP2 regulates epithelial properties by recruiting Par3 to the plasma membrane, facilitating the formation of adherens junctions and preventing epithelial-mesenchymal transformation.

Human cells’ emergency response could lead to better cancer treatment, research finds

Researchers found that a critical enzyme called AAG plays a crucial role in making cells respond to stress by communicating between different parts of the cell. This new understanding could lead to improved cancer treatments using alkylating agents, a class of drugs commonly used in chemotherapy.

Immunotherapy plus chemotherapy before surgery improves outcomes for lung cancer patients

Adding immunotherapy to chemotherapy before surgery reduced the risk of recurrence and death in lung cancer patients by 37%, according to a phase III trial. The treatment also led to a nearly twelvefold increase in pathological complete response, with 24% of patients achieving no active cancer remaining when the tumor was removed.

New oncogenic mechanisms in lymphoma via extracellular vesicles discovered

Researchers have identified a new mechanism of action for extracellular vesicles in the development and progression of lymphomas. sPLA2 secreted by tumor-associated macrophages degrades EV-derived phospholipids, enhancing EV function and inducing vital phenomena. This discovery may lead to new drug targets for cancer treatment.

Getting fuel to an invading cell's front line

Researchers have identified two glucose transporters that disrupt the energy supply to invading worm cells and stop them in their tracks. By deactivating these genes, glucose and ATP levels dropped, and worm cells stalled their spread. This discovery could lead to new ways to cut off cancer cells' fuel lines and prevent metastasis.

Burst of rapid cell motion in 3D tumor model

A new phenomenon was discovered where increased pressure leads to a sudden burst of rapid and coordinated cellular motion, spraying outwards from the tumour. This fluid-like pushing mechanism can kill cancer cells but also enables them to survive and multiply in new environments.

Chronic lactate exposure leads to cellular disruptions implicated in cancer and possibly T2 diabetes

Researchers found that chronic lactate exposure can lead to cellular disruptions, decreased fatty acid transport, and alterations of mitochondrial membranes, which may contribute to the development of heart failure and type 2 diabetes. The study suggests that lactate accumulation could be a major player in disease progression.
