Pancreatic stellate cells in chronic pancreatitis

, 2011
It is now generally accepted that activated pancreatic stellate cells (PSCs) are the principal effector cells in pancreatic fibrosis, a characteristic histological feature of chronic pancreatitis. PSC activation is associated with loss of cytoplasmic vitamin A containing lipid droplets, expression of cytoskeletal protein alpha-smooth muscle actin (αSMA)

Cancer‐Associated Fibroblasts Promote Tumor Immunosuppression in Hepatocellular Carcinoma via the NNMT‐ANGPTL4 Axis

Advanced Science, EarlyView.
ABSTRACT Background & Aims: Cancer‐associated fibroblasts (CAFs) drive immunosuppression in hepatocellular carcinoma (HCC). However, their metabolic regulation remains poorly defined. We investigated the role of nicotinamide N‐methyltransferase (NNMT) in CAFs. Approach & Results: High NNMT expression in CAF tissues was confirmed by western blotting and

Pancreatic stellate cells facilitate pancreatic cancer cell viability and invasion

Oncology Letters, 2018
The biological features of pancreatic cancer and the associated hypoxic environment around the cancer cells often lead to resistance to radiotherapy and chemotherapy. The present study was performed in order to explore the effect pancreatic stellate cells (PSCs) have on the proliferation of pancreatic cancer cells. In the present study, PSCs from human

RBM10 Deficiency Promotes Anti‐PD‐1 Resistance in LUAD via STING Alternative Splicing‐Driven CCL7 Signaling and Macrophage Polarization

Advanced Science, EarlyView.
RBM10 deficiency promotes anti‐PD‐1 resistance in lung adenocarcinoma by altering STING alternative splicing, which enhances CCL7 secretion and CCR2‐dependent M2 macrophage polarization. A positive feedback loop via mitochondrial transfer sustains this immunosuppression.

Alteration of pancreatic cancer cell functions by tumor-stromal cell interaction

Frontiers in Physiology, 2013
Pancreatic cancer shows a characteristic tissue structure called desmoplasia, which consists of dense fibrotic stroma surrounding cancer cells. Interactions between pancreatic cancer cells and stromal cells promote invasive growth of cancer cells and ...

The Development and Pilot Clinical Study of CD147 Targeted Antagonistic Peptide Probe for Tumor Imaging

Advanced Science, EarlyView.
This study establishes [68Ga]Ga‐DOTA‐AP9 as a first‐in‐human CD147‐targeted PET tracer with favorable safety and specific tumor uptake. Tracer accumulation correlates with CD147 expression in patients, enabling noninvasive quantification of CD147‐positive malignancies.

Inhibition of ERK1/2 in cancer-associated pancreatic stellate cells suppresses cancer–stromal interaction and metastasis

Journal of Experimental & Clinical Cancer Research, 2019
Background Extracellular signal-regulated kinases (ERKs) have been related to multiple cancers, including breast cancer, hepatocellular cancer, lung cancer and colorectal cancer.

Large‐Scale Genomics Reveals Three‐Source Ancestry and Layered Adaptation to High Altitude in Tibetan Chickens

Advanced Science, EarlyView.
Whole‐genome analysis of 1,054 chickens reveals three ancestral sources (NWC, SYA, and SHF) with distinct temporal entry patterns into the Tibetan Plateau. Route‐specific selection scans, calibrated against a demographic null, suggest complementary functional enrichments—vascular homeostasis (NWC), calcium signaling and cardiac adaptation (SYA), and ...

Severe fibrosis of the pancreas in chronic pancreatitis: main pathological components, immunophenotype of fibrogenic cells and collagen

Patologìâ, 2013
Pathomorphological feature of chronic pancreatitis (CP) is the development of pancreatic fibrosis with the accumulation of various collagen types, tubulin, fibronectin, laminin, and also intermediate filament proteins produced by activated pancreatic ...
