A proliferative subtype of colorectal liver metastases exhibits hypersensitivity to cytotoxic chemotherapy.

Personalized treatment approaches for patients with limited liver metastases from colorectal cancer are critically needed. By leveraging three large, independent cohorts of patients with colorectal liver metastases (n = 336), we found that a proliferative subtype associated with elevated CIN70 scores is linked to immune exclusion, increased metastatic proclivity, and inferior overall survival in colorectal liver metastases; however, high CIN70 scores generate a therapeutic vulnerability to DNA-damaging therapies leading to improved treatment responses. We propose CIN70 as a candidate biomarker to personalize systemic treatment options for patients with metastatic colorectal cancer.

Metastasis suppressor 1 (MTSS1) expression is associated with reduced in-vivo metastasis and enhanced patient survival in lung adenocarcinoma.

Metastasis suppressor 1 (MTSS1) has been shown to be a metastasis suppressor in a number of cancers. However, its role in lung adenocarcinoma is largely unknown. To evaluate the significance of MTSS1 expression on lung adenocarcinoma metastatic properties, the gain or loss of MTSS1 in in vivo and in vitro experiments were employed.

Myricetin induces apoptosis by inhibiting P21 activated kinase 1 (PAK1) signaling cascade in hepatocellular carcinoma.

Hepatocellular carcinoma is one of the most common malignancies worldwide and evidence suggests that Ras signaling regulates various hallmarks of cancer via regulating several effector pathways such as ERK and PI3K. The aim of the present study is to understand the efficacy of a flavonoid myricetin for the first time in inhibiting the downstream target p21 activated kinase 1 (PAK1) of Ras signaling pathway in hepatocellular carcinoma. The analysis of gene expression revealed that myricetin inhibits PAK1 by abrogating the Ras-mediated signaling by decelerating Wnt signaling, the downstream of Erk/Akt, thereby inducing intrinsic caspase-mediated mitochondrial apoptosis by downregulating the expression of anti-apoptotic Bcl-2 and survivin and upregulating pro-apoptotic Bax.

Receptor channel TRPC6 orchestrate the activation of human hepatic stellate cell under hypoxia condition.

Hepatic stellate cells (HSCs), a specialized stromal cytotype have a great impact on the biological behaviors of liver diseases. Despite this fact, the underlying mechanism that regulates HSC still remains poorly understood. The aim of the present study was to understand the role of TRPC6 signaling in regulating the molecular mechanism of HSCs in response to hypoxia.

Shigella dysenteriae modulates BMP pathway to induce mucin gene expression in vivo and in vitro.

Mucosal epithelial cells in the intestine act as the first line of host defense against pathogens by increasing mucin production for clearance. Despite this fact, the underlying molecular mechanisms by which Shigella dysenteriae transduce mucin gene expression remain poorly defined. The goal of this study was to determine the role of Bone morphogenetic protein (BMP) pathway in mucin gene expression during S.
