Kirsten rat sarcoma virus (KRAS) gene mutation is common in colorectal cancer (CRC) and is often predictive of treatment failure and poor prognosis. To understand the mechanism, we compared the transcriptome of CRC patients with wild-type and mutant KRAS and found that KRAS mutation is associated with the overexpression of a secreted serine protease, kallikrein-related peptidase 10 (KLK10). Moreover, using in vitro and in vivo models, we found that KLK10 overexpression favors the rapid growth and liver metastasis of KRAS mutant CRC and can also impair the efficacy of KRAS inhibitors, leading to drug resistance and poor survival.

Background And Objectives: Preliminary experiments have revealed the abnormally high expression level of adropin in pancreatic ductal adenocarcinoma (PDA). This study investigated the role of adropin in the progression of PDA.
Methods: The paraffin-embedded samples of 20 patients with PDA were obtained from the hospital biobank, and immunohistochemistry was used to evaluate adropin expression.
Objectives: The M2 polarization of tumor-associated macrophages (TAMs) facilitates the growth, invasion and metastasis of tumor cells. Here, we investigated the role of miR-216b in the M2 polarization of TAMs in colorectal cancer (CRC).
Methods: The expression of genes were examined by quantitative real-time polymerase chain reaction, Western blot, enzyme-linked immunosorbent assay and immunohistochemistry.
Background: Forkhead box protein C1 (FOXC1) is a transcription factor overexpressed in multiple cancers and is associated with poor prognosis. However, the function of FOXC1 in gastric cancer remains largely unknown.
Aim: This study aims to explore the role of FOXC1 in promoting gastric cancer metastasis.
