The expression levels of the Wilms' tumor gene WT1 were examined in 56 cases of head and neck squamous cell carcinoma (HNSCC) using quantitative real-time reverse transcriptase-polymerase chain reaction (RT-PCR). They included 4 cases of floor of mouth, 9 of gingiva, 25 of tongue, 10 of oropharynx, 3 of hypopharynx, and 5 larynx squamous cell carcinoma (SCC). All (100%) of 4 cases of floor of mouth, 5 (56%) of 9 gingiva, 17 (68%) of 25 tongue, 8 (80%) of 10 oropharynx, all (100%) of 3 hypopharynx, and all (100%) of 5 larynx SCC overexpressed the WT1 gene in the range of 3.07 x 10(-4)-8.60 x 10(-1) levels (the WT1 expression level in K562 leukemic cells was defined as 1.0). Thus, 42 (75%) out of 56 cases of HNSCC overexpressed the WT1 gene. The high expression level of the WT1 gene significantly correlated with poor histological tumor differentiation and high tumor stage of HNSCC. Immunohistochemical analysis confirmed the expression of WT1 protein in 6 cases (one floor of mouth, 2 tongue, 2 oropharynx, and one larynx SCC) with overexpression of the WT1 gene. The direct sequencing analysis of the WT1 genomic DNA showed no mutations in any of 10 exons of the WT1 gene in 5 different HNSCC. These findings suggest an important role of the wild-type WT1 gene in the tumorigenesis of HNSCC.

To investigate the clinicopathological characteristics, immunophenotypes, diagnostic criteria and differential diagnosis of atrophic kidney-like lesion (AKLL). Three cases of AKLL were collected from April 2021 to October 2023 at the Xiangya Hospital of Central South University, Changsha, Zhejiang Provincial People's Hospital, Hangzhou and Ningbo Clinical Pathology Diagnosis Center, Ningbo, China. The clinical, morphological, and immunohistochemical characteristics were analyzed.

This study investigates how microbiome colonization influences the development of intestinal type 3 immunity in neonates. The results showed that reduced oxygen levels in the small intestine of neonatal rats induced by Saccharomyces boulardii accelerated microbiome colonization and type 3 immunity development, which protected against Salmonella enterica serovar Typhimurium infection. Microbiome maturation increased the abundance of microbiome-encoded bile salt hydrolase (BSH) genes and hyocholic acid (HCA) levels.

Capicua transcriptional repressor (CIC)-rearranged sarcoma (CRS) is a rare and recently described tumor that most commonly affects patients between 15 and 30 years of age. It is an undifferentiated round cell malignancy, with a disease defining CIC fusion, with double homeobox 4 (DUX4) being the most common partner. Here, we report a 77-year-old woman who presented with a cutaneous thigh mass with a clinical morphology suggesting Merkel cell carcinoma.

BACKGROUND Limb-girdle muscular dystrophy recessive 1 (LGMDR1) is an autosomal recessive degenerative muscle disorder characterized by progressive muscular weakness caused by pathogenic variants in the CAPN3 gene. Desmoplastic small round cell tumors (DSRCT) are ultra-rare and aggressive soft tissue sarcomas usually in the abdominal cavity, molecularly characterized by the presence of a EWSR1::WT1 fusion transcript. Mouse models of muscular dystrophy, including LGMDR1, present an increased risk of soft tissue sarcomas.

Background: The complexity of acute myeloid leukemia (AML) is increasingly recognized through the identification of distinct subgroups, including those with an APL-like immunophenotype characterized by the absence of CD34 and HLA-DR expression, which is widely recognized as a representative immunophenotype in acute promyelocytic leukemia (APL). This study sought to understand the clinical, molecular, and prognostic differences between AML patients with and without this phenotype.
Methods: This study retrospectively analysed 191 de novo non-M3 AML patients and identified 32 patients with the CD34HLA-DR phenotype resembling APL-like immunophenotype, considered as the experimental group.
