Development of the Goose Tongue Filiform Papillae: Could it be Tooth-Like Sense Organs?

Int. j. morphol; 41 (6), 2023
SUMMARY: The geese's tongue filiform papillae are particularly long, and exhibit the same morphology of a tooth, evoking the lingual teeth of several fishes. In adult animals, they contain numerous mechanical Herbst's corpuscles but no taste buds. In the embryo, they appear since stage 38 and acquire the...

Expression of the homeobox proteins Dlx-5 and TLX1 during the development of cat testis

Int. j. morphol; 40 (3), 2022
SUMMARY: Recent studies have shown that homeobox proteins play an important role in the formation and development of tissues and organs in the embryonic period. In our study, the distribution of Dlx-5 and TLX proteins, which are members of the homeobox family, in the testis, epididymis and ductus deferen...

The risk of nonsyndromic cleft lip with or without cleft palate and Vax1 rs7078160 polymorphisms in southern Han Chinese

Abstract Introduction: Non-syndromic cleft lip with or without cleft palate is a common worldwide birth defect due to a combination of environmental and genetic factors. Genome-wide association studies reported the rs7078160 of Vax1 is closely related to non-syndromic cleft lip with or without cleft pal...

ING3 and ING4 immunoexpression and their relation to the development of benign odontogenic lesions

Braz. dent. j; 32 (4), 2021
Abstract The Inhibitor of Growth (ING) gene family is a group of tumor suppressor genes that play important roles in cell cycle control, senescence, DNA repair, cell proliferation, and apoptosis. However, inactivation and downregulation of these proteins have been related in some neoplasms. The present s...

Nicotine promotes the development of oral leukoplakia via regulating peroxiredoxin 1 and its binding proteins

Braz. j. med. biol. res; 54 (9), 2021
Tobacco can induce reactive oxygen species (ROS) production extensively in cells, which is a major risk factor for oral leukoplakia (OLK) development. Peroxiredoxin 1 (Prx1) is a key antioxidant protein, upregulated in a variety of malignant tumors. We previously found that nicotine, the main ingredient ...

Combined pituitary hormone deficiency caused by PROP1 mutations: update 20 years post-discovery

ABSTRACT The first description of patients with combined pituitary hormone deficiencies (CPHD) caused by PROP1 mutations was made 20 years ago. Here we updated the clinical and genetic characteristics of patients with PROP1 mutations and summarized the phenotypes of 14 patients with 7 different pathogeni...

Frequency of Variants in DNA-Repair Genes in a Southwest Colombian Population

Objective To describe the frequency of mutations in DNA-repair genes in a southwestern Colombian population. Methods We have designed an observational study, including 162 people from all ages from southwest Colombia. We have extracted and collected their DNA in filters. We have immersed the DNA in a...

Urinary EN-2 to predict prostate cancer: Systematic review and meta-analysis

Summary Introduction: Prostate cancer is the second type of cancer diagnosed and the fifth cause of death in men worldwide. Early diagnosis helps to control disease progression. Currently, prostate specific antigen is the standard biomarker, as it has a broad scope of identification and, thus, new and m...

MiR-320 inhibits the growth of glioma cells through downregulating PBX3

Biol. Res; 50 (), 2017
BACKGROUND: MiR-320 is downregulated in multiple cancers, including glioma and acts as tumor suppressor through inhibiting tumor cells proliferation and inducing apoptosis. PBX3 (Pre-B cell leukemia homeobox 3), a putative target gene of miR-320, has been reported to be upregulated in various tumors and ...

CDX-2, MUC-2 and B-catenin as intestinal markers in pure mucinous carcinoma of the breast

Biol. Res; 47 (), 2014
BACKGROUND: Pure mucinous adenocarcinoma of the breast is a rare entity characterized by the production of variable amounts of mucin comprising 1% to 6% of breast carcinomas. Some mucinous adenocarcinomas have shown expression of intestinal differentiation markers such as MUC-2. This study examines the e...
