Background: This study aimed to explore the expression level and transcriptional regulation mechanism of Extra Spindle Pole Bodies Like 1 (ESPL1) in bladder cancer (BC).

Methods: A multicentre database of samples (n = 1391) was assayed for ESPL1 mRNA expression in BC and validated at the protein level by immunohistochemical (IHC) staining of in-house samples (n = 202). Single-cell sequencing (scRNA-seq) analysis and enrichment analysis explored ESPL1 distribution and their accompanying molecular mechanisms.

Triosephosphate isomerase 1 may be a risk predictor in laryngeal squamous cell carcinoma: a multi-centered study integrating bulk RNA, single-cell RNA, and protein immunohistochemistry.

Background: Although great progress has been made in anti-cancer therapy, the prognosis of laryngeal squamous cell carcinoma (LSCC) patients remains unsatisfied. Quantities of studies demonstrate that glycolytic reprograming is essential for the progression of cancers, where triosephosphate isomerase 1 (TPI1) serves as a catalytic enzyme. However, the clinicopathological significance and potential biological functions of TPI1 underlying LSCC remains obscure.

ITGB4 Serves as an Identification and Prognosis Marker Associated with Immune Infiltration in Small Cell Lung Carcinoma.

Integrin beta 4 (ITGB4) is a vital factor for numerous cancers. However, no reports regarding ITGB4 in small cell lung carcinoma (SCLC) have been found in the existing literature. This study systematically investigated the expression and clinical value of ITGB4 in SCLC using multi-center and large-sample (n = 963) data.

Clinicopathological value of hematopoietic cell kinase overexpression in laryngeal squamous cell carcinoma tissues.

Pterostilbene (Pter) is reported to exhibit an anticancer effect in hepatocellular carcinoma (HCC). In order to explore the anticancer mechanism in HCC cells, the present study aimed to investigate whether pterostilbene (Pter) may increase phosphatase and tensin homolog (PTEN) expression through targeted downregulation of microRNA (miRNA/miR)-19a in hepatocellular carcinoma (HCC). The proliferation, apoptosis and cell cycle was analyzed in the SMMC‑7721 HCC cell line by MTT assays and flow cytometry methods.

Long non-coding RNA PTENP1 interacts with miR-193a-3p to suppress cell migration and invasion through the PTEN pathway in hepatocellular carcinoma.

Long non-coding RNA PTENP1, the pseudogene of PTEN tumor suppressor, was previously reported to be a tumour suppressor in some cancer types. However, the precise effects mediated by PTENP1 transcripts within intricate regulatory networks involving molecular interactions with PTEN and tumorigenicity in hepatocellular carcinoma (HCC) remains elusive. Here, we identify the critical biological functions of PTENP1 and discuss whether PTENP1 could directly interact with miR-193a-3p to affect the progression of HCC both and .

Upregulation of DARS2 by HBV promotes hepatocarcinogenesis through the miR-30e-5p/MAPK/NFAT5 pathway.

Background: Infection with the hepatitis B virus (HBV) is closely associated with the development of hepatocellular carcinoma (HCC). The osmoregulatory transcription factor nuclear factor of activated T-cells 5 (NFAT5) has been shown to play an important role in the development of many types of human cancers. The role of NFAT5 in HBV-associated HCC has never previously been investigated.

Hepatogenic differentiation from human adipose-derived stem cells and application for mouse acute liver injury.

Adipose-derived stem cells (ADSCs) derived from adipose tissue have the capacity to differentiate into endodermal, mesoderm, and ectodermal cell lineages in vitro, which are an ideal engraft in tissue-engineered repair. In this study, human ADSCs were isolated from subcutaneous fat. The markers of ADSCs, CD13, CD71, CD73, CD90, CD105, CD166, CYP3A4, and ALB were detected by immunofluorescence assays.

Antiperistaltic Side-to-Side Ileorectal Anastomosis is Associated with a Better Short-Term Fecal Continence and Quality of Life in Slow Transit Constipation Patients.

Background: Surgical treatment of refractory slow transit constipation (STC) is traditionally performed using end-to-side ileorectal anastomosis (SE-IRA) with total abdominal colectomy (TAC). Antiperistaltic side-to-side (SS) IRA is suggested to be a superior approach. Employing a well-characterized cohort of STC patients, we compared the postoperative outcomes of the 2 surgical approaches.

Liver regeneration and tumor growth in ligated and non-ligated lobes were evaluated prior to and following PVL.

Suppression of angiogenesis and tumor growth and using an anti-angiopoietin-2 single-chain antibody.

Hepatocellular carcinomas (HCCs) are tumors with a highly developed vascular architecture. HCC cells require access to blood vessels for growth and metastasis; therefore, the inhibition of angiogenesis represents a potential therapeutic target for HCC that may reduce the mortality and morbidity from HCC. Various attempts to develop an anti-angiogenic therapy have been made in past decades; however, modest results have been achieved in clinical trials and the challenge of HCC treatment remains.

5-Aza-2<-deoxycytidine induces hepatoma cell apoptosis via enhancing methionine adenosyltransferase 1A expression and inducing S-adenosylmethionine production.

In hepatocellular cancer (HCC), lack of response to chemotherapy and radiation treatment can be caused by a loss of epigenetic modifications of cancer cells. Methionine adenosyltransferase 1A is inactivated in HCC and may be stimulated by an epigenetic change involving promoter hypermethylation. Therefore, drugs releasing epigenetic repression have been proposed to reverse this process.

Operable severe obstructive jaundice: how should we use pre-operative biliary drainage?

Obstructive jaundice is a common surgical problem, and surgery in jaundiced patients is associated with a higher risk of postoperative complications than surgery in non-jaundiced patients. However, the efficacy of pre-operative biliary drainage (PBD) for patients with obstructive jaundice remains controversial. Many studies have been unable to confirm the benefit of PPB and have suggested that it should not be performed routinely.
