Abstract: Katanin subunits p60 and p80 are involved in microtubule-mediated cytoskeletal organization during cell division. Their aberrant expression has been found in prostate, breast, and non-small cell lung (NSCLC) cancers. It has recently been reported that compared with adjacent papillary thyroid carcinoma (PTC) tissues, both are highly expressed in tumor tissues. Here, we investigated whether katanin subunits p60 and p80 can be used as potential biomarkers for PTC to distinguish nodular goiter (NG).Immunohistochemistry was performed to investigate the expression of katanin subunits p60 and p80 in the tissues of 97 cases of PTC and NG. This cohort included 87 cases with PTC (74 classical or conventional (CPTC) and 13 follicular (FVPTC) variants) and 10 cases with NG.We found that katanin subunits p60 and p80 were expressed in PTC, but not in NG. The cutoff values of katanin p60 and p80 for PTC were 22.43% and 0.83%, respectively. The katanin subunit p60 was significantly associated with lymph node metastasis. Katanin subunit p80 was more highly expressed in CPTC than in FVPTC. The expression of the katanin subunit p60 was positively correlated with the expression of katanin p80 in PTC. Importantly, we found that overexpression of katanin p60 increased the expression of katanin p80 in a human papillary thyroid carcinoma KTC-1 cell line, which further supports the existence of katanin p60 and p80 feedback loops.Our results indicate that katanin subunits p60 and p80 may be used as potential PTC biomarkers to distinguish NG and may be novel therapeutic targets for PTC.

Impact of adolescent intermittent ethanol exposure on interneurons and their surrounding perineuronal nets in adulthood.

Authors:
Carol A Dannenhoffer Alexander Gómez-A Victoria A Macht Rayyanoor Jawad Elizabeth Blake Sutherland Ryan P Vetreno Fulton T Crews Charlotte A Boettiger Donita L Robinson

Alcohol Clin Exp Res 2022 05 1;46(5):759-769. Epub 2022 Apr 1.

Bowles Center for Alcohol Studies, School of Medicine, University of North Carolina at Chapel Hill, Chapel Hill, North Carolina, USA.

Background: Binge alcohol exposure during adolescence results in long-lasting alterations in the brain and behavior. For example, adolescent intermittent ethanol (AIE) exposure in rodents results in long-term loss of functional connectivity among prefrontal cortex (PFC) and striatal regions as well as a variety of neurochemical, molecular, and epigenetic alterations. Interneurons in the PFC and striatum play critical roles in behavioral flexibility and functional connectivity. Read More

Effect of Chemical Composition on Magnetic and Electrical Properties of Ferroelectromagnetic Ceramic Composites.

Authors:
Dariusz Bochenek Przemysław Niemiec Artur Chrobak

Materials (Basel) 2021 May 11;14(10). Epub 2021 May 11.

Faculty of Science and Technology, Institute of Physics, University of Silesia in Katowice, 41-500 Chorzów, Poland.

In this paper, ferroelectric-ferrimagnetic ceramic composites based on multicomponent PZT-type (PbZrTiO-type) material and ferrite material with different percentages in composite compositions were obtained and studied. The ferroelectric component of the composite was a perovskite ceramic material with the chemical formula PbBi(ZrTi)(NbMn)O (P), whereas the magnetic component was nickel-zinc ferrite with the chemical formula NiZnFeO (F). The process of sintering the composite compounds was carried out by the free sintering method. Read More

Katanin P60 and P80 in papillary thyroid carcinoma patients: Indicators for exacerbated tumor features and worse disease-free survival.

J Clin Lab Anal 2020 Dec 3;34(12):e23502. Epub 2020 Dec 3.

Department of General Surgery, Zhongshan Hospital Affiliated to Xiamen University, Xiamen, China.

Background: This study aimed to explore the clinical implications of katanin P60 and P80 (katanin P60/P80) regarding their correlations with clinicopathological features and survival profiles in papillary thyroid carcinoma (PTC) patients.

Methods: Tumor tissue and paired adjacent tissue specimens were obtained from 172 PTC patients who underwent lobectomy or thyroidectomy. Besides, immunohistochemistry assay and immunoreactive (IR) score (multiplying staining intensity score by density score) were used to determine katanin P60/P80 expressions. Read More
