β-Sitosterol Inhibits Tumor Growth and Amplifies Rituximab Sensitivity through Acid Sphingomyelinase/Ceramide Signaling in Diffuse Large B-Cell Lymphoma.

Rituximab (RTX) resistance is a notable challenge in treating diffuse large B-cell lymphoma (DLBCL). β-Sitosterol (β-ST) is a plant sterol that has been found in a broad variety of fruits, spices, and medicinal plants. The antineoplastic properties of β-ST are established in various solid malignancies; however, its effect on DLBCL is uncharted.

Survival outcomes in locally advanced dMMR rectal cancer: surgery plus adjunctive treatment vs. surgery alone.

Background: Recent studies have shown that deficient mismatch repair (dMMR) rectal cancer may be related to treatment resistance, resulting in a worse prognosis than proficient MMR (pMMR) rectal cancer. The purpose of this study was to explore whether surgery plus other treatments (radiotherapy and chemotherapy) can bring more benefits to these patients than surgery alone.

Methods: A retrospective study of 168 patients with rectal adenocarcinoma who underwent total mesorectal excision was conducted using immunohistochemical methods to determine MMR status and a propensity score matching model to minimize potential confounding factors between subgroups of patients with different treatment regimens.

Stage III deficient mismatch repair colon patients get greater benefit from earlier starting oxaliplatin-based chemotherapy regimen.

We evaluate the prognostic value of chemotherapy and other prognostic factors on overall survival among colon patients with deficient mismatch repair (dMMR), and determine the optimum time to start chemotherapy after surgery. Data of 306 colon cancer patients with dMMR who received radical surgery were collected from three Chinese centers between August 2012 and January 2018. Overall survival (OS) was assessed with the Kaplan-Meier method and log-rank.

The stool methylation test is more robust than blood tests for methylated , CEA, CA19-9 and CA724: a diagnostic test for the early detection of colorectal neoplasms.

Background: Methylated (mSDC2) in stool samples has been found to be associated with colorectal cancer (CRC) and precancerous lesions. However, the available data are limited, and no previous studies have compared the analysis of mSDC2 with other diagnostic tests. Thus, we aimed to evaluate the clinical performance of a stool mSDC2 test and compare its performance with that of blood-based tests for methylated (mSEPT9), carcinoembryonic antigen (CEA), carbohydrate antigen 19-9 (CA19-9) and carbohydrate antigen 724 (CA724) in detecting colorectal neoplasms.

Young Patients With Colorectal Cancer Have Higher Early Mortality but Better Long-Term Survival.

Introduction: To define the prognosis of colorectal cancer (CRC) in young patients and to compare their postoperative treatment with that of older patients.

Methods: This multicenter study enrolled 5,457 patients with primary CRC who underwent surgical resection. The overall survival (OS), clinicopathologic characteristics, and postoperative treatment of 253 young patients aged 18-44 years and 5,204 older patients aged 44-80 years were analyzed.

Effects of deficient mismatch repair on the prognosis of patients with stage II and stage III colon cancer during different postoperative periods.

Background: We evaluated the prognostic role of deficient mismatch repair (dMMR) systems in stage II and stage III colon cancer patients during different postoperative periods. We also assessed whether patients aged ≥75 could benefit from chemotherapy.

Methods: This retrospective study was conducted across three medical centers in China.

Modifiable lifestyle factors have a larger contribution to colorectal neoplasms than family history.

Background:  Screening recommendations for colorectal cancer (CRC) are mainly based on family history rather than lifestyle risk factors. We aimed to assess and compare risk factors for colorectal neoplasm (CRN) and evaluate trends in neoplasm detection rates during the three rounds of screening from 2012 to 2020 in Tianjin, China.

Methods: This study was based on 89,535 first-recorded colonoscopies in Tianjin CRC screening program, 2012-2020.

Circulating Methylated SEPT9 DNA Analyses to Predict Recurrence Risk and Adjuvant Chemotherapy Benefit in Stage II to III Colorectal Cancer.

BACKGROUND We aimed to evaluate the ability of circulating cell-free methylated SETP9 DNA (mSEPT9) to identify recurrence and to determine its clinical utility in adjuvant chemotherapy (ACT) regimen decisions. MATERIAL AND METHODS This study enrolled 426 patients with stage II-III CRC who received radical resection between January 8, 2018, and November 30, 2020. The median follow-up duration was 15.

The prognostic and clinical value of p53 upregulated modulator of apoptosis expression in solid tumors: a meta-analysis and TCGA data review.

Background: Previous studies have reported the prognostic value of p53 upregulated modulator of apoptosis (PUMA) in numerous human tumors, but the conclusions have not been consistent. Therefore, this meta-analysis and the Cancer Genome Atlas (TCGA) data analysis were performed to estimate the prognostic significance of PUMA in solid tumors.

Research Design And Methods: A search was conducted in PubMed, Embase, Web of Science, Cochrane Library and CNKI up to 21 July 2022.

Effector Sntf2 Interacted with Chloroplast-Related Protein Mdycf39 Promoting the Colonization of in Apple Leaf.

Glomerella leaf spot of apple, caused by , is a devastating disease that leads to severe defoliation and fruit spots. The species secretes a series of effectors to manipulate the host's immune response, facilitating its colonization in plants. However, the mechanism by which the effector of inhibits the defenses of the host remains unclear.

Mismatch repair system deficiency is associated with chemoradiotherapy resistance in locally advanced rectal adenocarcinoma patients.

Background And Objectives: Previous studies have concluded that colorectal cancer patients with deficient mismatch repair (dMMR) usually have a good prognosis. However, some studies have suggested that the prognosis of rectal cancer patients with dMMR appears to be worse. Our aim was to investigate chemoradiotherapy resistance in dMMR rectal tumors.

Carbamoyl phosphate synthetase subunit Cpa1 interacting with Dut1, controls development, arginine biosynthesis, and pathogenicity of Colletotrichum gloeosporioides.

Carbamoyl phosphate synthetase is involved in arginine biosynthesis in many organisms. In this study, we investigate the biological function of Cpa1, a small subunit of carbamoyl phosphate synthetase of Colletotrichum gloeosporioides. The deletion of the CPA1 gene affected vegetative growth, arginine biosynthesis, and fungal pathogenicity.

A SET domain-containing protein involved in cell wall integrity signaling and peroxisome biogenesis is essential for appressorium formation and pathogenicity of Colletotrichum gloeosporioides.

The chromatin modulator Set5 plays important regulatory roles in both cell growth and stress responses of Saccharomyces cerevisiae. However, its function in filamentous fungi remains poorly understood. Here, we report the pathogenicity-related gene CgSET5 discovered in a T-DNA insertional mutant M285 of Colletotrichum gloeosporioides.

Influence of cerebrovascular reactivity on outcome of the patients with ≥50% symptomatic unilateral middle cerebral artery stenosis.

Unlabelled: Purpose/aim of the study: Cerebrovascular reactivity (CVR) reflects the vasodilatory reserve of cerebral resistance vessels, which is an important marker for assessing cerebrovascular disease. The present study is to investigate whether CVR impairment increases adverse long-term outcome risk of patients with ≥ 50% symptomatic unilateral middle cerebral artery (MCA) stenosis (ischemic stroke (IS) or transient ischemic attack (TIA)).

Material And Methods: Digital subtraction angiography (DSA) was used to assess the degree of stenosis, and perfusion CT and 5% CO inhalation were adopted to evaluate CVR.
