LncRNA CR749391 acts as a tumor suppressor to upregulate KLF6 expression via interacting with miR-181a in gastric cancer.

Exp Ther Med

January 2020

Department of Gastroenterology, Guangzhou Digestive Disease Center, Guangzhou Key Laboratory of Digestive Disease, Guangzhou First People's Hospital, Guangzhou Medical University, Guangzhou, Guangdong 510180, P.R. China.

Long non-coding RNAs (lncRNAs) are novel regulators for post-transcriptional gene expression, and altered lncRNAs function and expression are associated with tumorigenesis and cancer progression, although the biological functions of most lncRNAs in various cancer types and their underlying regulatory interactions have remained largely elusive. Our previous study identified microRNA (miR)-181a as a regulator of Kruppel-like factor 6 (KLF6). In the present study, a bioinformatical analysis was performed to identify the novel lncRNA CR749391 as a potential regulator of miR-181a that contains four putative binding sites.

Pro-Death or Pro-Survival: Contrasting Paradigms on Nanomaterial-Induced Autophagy and Exploitations for Cancer Therapy.

Acc Chem Res

November 2019

Department of General Surgery, Guangzhou Digestive Disease Center, Guangzhou First People's Hospital, School of Medicine and Institutes for Life Sciences , South China University of Technology, Guangzhou 510006 , China.

Autophagy is a critical lysosome-mediated cellular degradation process for the clearance of damaged organelles, obsolete proteins, and invading pathogens and plays important roles in the pathogenesis and treatment of human diseases including cancer. While not a cell death process per se, autophagy is nevertheless intimately linked to a cell's live/die decision. Basal autophagy, operating constitutively at low levels in essentially every mammalian cell, is vital for maintaining cellular homeostasis and promotes cell survival.

Immune checkpoint molecules. Possible future therapeutic implications in autoimmune diseases.

J Autoimmun

November 2019

Department of General Surgery, Guangzhou Digestive Disease Center, Guangzhou First People's Hospital, School of Medicine, South China University of Technology, Guangzhou, Guangdong, 510006, China; Chronic Disease Laboratory, Institutes for Life Sciences, South China University of Technology, Guangzhou, 510006, China. Electronic address:

During host immune response, an initial and sufficient activation is required to avoid infection and cancer, yet an excessive activation bears the risk of autoimmune reactivity and disease development. This fastidious balance of the immune system is regulated by co-stimulatory and co-inhibitory molecules, also known as immune checkpoints. Both excessive co-stimulation and insufficient co-inhibition can induce the activation and proliferation of autoreactive cells that may lead to the development of autoimmune diseases.

  • Gut microbiota and bacterial translocation are key factors influencing immune responses and tolerance, particularly relating to autoimmune conditions, though the exact mechanisms remain unclear.
  • Using a specific mouse model of autoimmune cholangitis, the study found that changes in gut microbiota composition can reduce immune-related damage when antibiotics are administered.
  • Additionally, mice lacking toll-like receptor 2 (TLR2) experienced worsened conditions due to compromised gut barrier function, highlighting the role of gut permeability and microbiota translocation in liver damage associated with the disease.

Department of Gastrointestinal Surgery, Guangzhou Digestive Disease Center, Guangzhou First People's Hospital, Guangzhou Medical University, Guangzhou Guangdong 510180, P.R. China.

Colorectal cancer (CRC) is the third most common type of cancer; however, the molecular mechanisms underlying colorectal tumor metastasis and growth remain elusive. Recently, accumulating evidence has indicated that long non‑coding RNAs (lncRNAs) play a critical role in CRC progression and metastasis; however, the biological role and clinical significance of lncRNA 00152 (lnc00152) in CRC remains largely unknown. Thus, in this study, lnc00152 expression was measured in 80 human CRC tissue samples, 40 non‑cancerous tissue samples, and 3 CRC cell lines (SW480, SW620 and LoVo) using RT‑qPCR.
