Checkpoint Molecules Predict Response to Immunotherapy in Cancer
cells

Heij et al. investigated the expression of checkpoint molecules in the tumor microenvironment of intrahepatic cholangio-carcinoma. They found that co-expression patterns of checkpoint molecules such as PD-L1 and TIGIT correlate with metastases and poor prognosis. TissueFAXS and StrataQuest were used to image the mIF-stained samples and assess protein expression.

AI-Assisted Analysis of ‘Anti-/Pro-Tumor’ Profiles for Pancreatic Adenocarcinoma
Cancer Biology & Medicine

To predict survival of patients with pancreatic adenocarcinoma, Zhou et al. performed an AI-assisted comprehensive analysis of CD8+ T cells, cancer stem cells (CSCs), and tumor budding (TB). They used StrataQuest image analysis software to automatically detect and quantify tumor-infiltrating CD8+ T cells, CD133+ CSCs, and CK19+ TB.

Characterization of the Spatial Immune Context of Lung Cancer
International Journal of Molecular Sciences

In a recent study, Imamura et al. investigated the role of debrin-expressing tumor infiltration lymphocytes (TIL) in lung cancer. The high-end image analysis solution, StrataQuest, was used for the automatic tissue classification and localization of CD3+/debrin+ cellular phenotypes in the tumor cell nest, as well as in the stroma.

COL8A1 Promotes Tumor in Pancreatic Ductal Adenocarcinoma
Matrix Biology

Yan et al. investigated several collagen subtypes involved in pancreatic ductal adenocarcinoma desmoplasia. Based on this study, COL8A1 was suggested as a new marker for predicting poor chemotherapy responsiveness and survival. The TissueFAXS imaging platform and StrataQuest analysis solution were used to image and segment morphological structures.

Erk1/2-Dependent HNSCC Cell Susceptibility to Erastin-Induced Ferroptosis
cells

Savic et al. investigated the Erk 1/2 pathway role in ferroptosis induction by targeting xCT protein during the treatment of HNSCC. They found erastin to be a potent ferroptosis inducer which is strongly dependent on Erk 1/2 kinases. TissueFAXS and HistoQuest were used to image the IHC-stained samples and calculate the percentage of xCT-positive cells.

CpG Methylation Influence on Protease Serine 3 Isoforms in Lung Cancer
Acta Pharmaceutica Sinica B

Lin et al. investigated the UHRF1/DNMT1–MZF1 axis in the context of CpG methylation of protease serine 3, a protein with several isoforms that show paradoxical effects. To differentiate the isoforms, the researchers employed 7-marker multiplex staining and performed a quantitative analysis using TissueFAXS SPECTRA and StrataQuest.
