Integrin-linked kinase (ILK) has emerged as a controversial pseudokinase protein that plays a crucial role in the signaling process initiated by integrin-mediated signaling. However, ILK also exhibits a scaffolding protein function inside cells, controlling cytoskeletal dynamics, and has been related to non-neoplastic diseases such as chronic kidney disease (CKD). Although this protein always acts as a heterotrimeric complex bound to PINCH and parvin adaptor proteins, the role of parvin proteins is currently not well understood. Using in silico approaches for the design, we have generated and prepared a set of new tripeptides mimicking an α-parvin segment. These derivatives exhibit activity in phenotypic assays in an ILK-dependent manner without altering kinase activity, thus allowing the generation of new chemical probes and drug candidates with interesting ILK-modulating activities.

Article Synopsis
- Human mesenchymal stem cells (hMSCs) react to mechanical stimuli like stiffness and fluid viscosity, which impacts their behavior.
- In environments with high fluid viscosity, hMSCs favor an osteogenic (bone-forming) phenotype over an adipogenic (fat-forming) one by altering their actin structure and enhancing cellular activities.
- This research highlights fluid viscosity as an important factor that not only influences hMSC differentiation but also encourages a more immunosuppressive M2 macrophage phenotype.

Objective: Intrahepatic cholangiocarcinoma (iCCA) is a highly lethal hepatobiliary malignancy with an increasing incidence annually. Extensive research has elucidated the existence of a reciprocal interaction between platelets and cancer cells, which promotes tumor proliferation and metastasis. This study aims to investigate the function and mechanism underlying iCCA progression driven by the interplay between platelets and tumor cells, aiming to provide novel therapeutic strategies for iCCA.

Glioblastoma cells exhibit remarkable plasticity, enabling them to adapt to environmental cues and transition through various developmental-like states with distinct properties. In this issue of Developmental Cell, Loftus et al. identify ILK as an intrinsic regulator of glioblastoma cell transitions between progenitor-like and mesenchymal/astrocyte-like states.

: Pleural mesothelioma (PM) is a rare type of cancer with poor prognosis. Prognostic and predictive biomarkers could improve treatment strategies in these patients. Programmed death ligand 1 (PD-L1), integrin-linked kinase (ILK) and breast cancer gene 1-associated protein (BAP-1) have been proposed to predict outcomes in PM, but existing data are limited and controversial.

Background Colorectal cancer (CRC) is the third most frequently diagnosed cancer globally, with a high incidence of morbidity and mortality. Early diagnosis of CRC is crucial for determining appropriate treatment regimens, thereby prolonging overall survival rates and improving prognostic outcomes. Objectives This study aimed to investigate the expression profiles of specific proteins in the lymph nodes (LNs) of CRC patients, including integrin-linked kinase (ILK), vascular endothelial growth factor A (VEGFA), and ephrin type-A receptor 2 (EphA2), through immunohistochemical studies.
