Abstract
Disrupting microtubule dynamics has emerged as a promising strategy for cancer treatment. However, drug resistance remains a challenge hindering the development of microtubule-targeting agents. In this work, a novel class of diaryl substituted fused heterocycles were designed, synthesized, and evaluated, which were demonstrated as effective dual katanin and tubulin regulators with antitumor activity. Following three rounds of stepwise optimization, compound 21b, featuring a 3H-imidazo[4,5-b]pyridine core, displayed excellent targeting capabilities on katanin and tubulin, along with notable antiproliferative and antimetastatic effects. Mechanistic studies revealed that 21b disrupts the microtubule network in tumor cells, leading to G2/M cell cycle arrest and apoptosis induction. Importantly, 21b exhibited significant inhibition of tumor growth in MDA-MB-231 and A549/T xenograft tumor models without evident toxicity and side effects. In conclusion, compound 21b presents a novel mechanism for disrupting microtubule dynamics, warranting further investigation as a dual-targeted antitumor agent with potential antimultidrug resistance properties.

Abstract
The up-regulation of Katanin P8 has been reported to be correlated with a larger tumor size and lymph node metastasis in non-small-cell lung cancer (NSCLC) patients. And lncRNA MALAT1 was demonstrated to promote the proliferation of chronic myeloid leukemia cells via modulating miR-328. 135 lung cancer patients were divided into 6 groups according to their genotypes of MALAT1. The expression of KATNB1 was negatively correlated with the GGGT genotype of MALAT1. Decreased lymph node size and tumor size of brain metastatic lung were observed in patients with GGGT genotype of MALAT1. The luciferase activities of MALAT1 and KATNB1 were remarkably suppressed by miR-328 in A549 and H460. And the down-regulation of MALAT1 or up-regulation of miR-328 significantly repressed the KATNB1 expression in A549 and H460 cells. MALAT1 expression was reduced in patients carrying haplotype GGGT. A signaling pathway of MALAT1/miR-328/KATNB1 was established to explain the down-regulation of KATNB1 mRNA in patients carrying haplotype GGGT and reduced lymph node size in lung cancer and tumor size in brain metastatic lung cancer.

[PMID: 35713446 PMCID: PMC9276123 DOI: 10.1097/md.0000000000029402] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/28/2021] [Accepted: 04/18/2022] [Indexed: 12/24/2022] Open
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.

Abstract
The katanin family of microtubule-severing enzymes is critical for cytoskeletal rearrangements that affect key cellular processes like division, migration, signaling, and homeostasis. In humans, aberrant expression, or dysfunction of the katanins, is linked to developmental, proliferative, and neurodegenerative disorders. Here, we review current knowledge on the mammalian family of katanins, including an overview of evolutionary conservation, functional domain organization, and the mechanisms that regulate katanin activity. We assess the function of katanins in dividing and non-dividing cells and how their dysregulation promotes impaired ciliary signaling and defects in developmental programs (corticogenesis, gametogenesis, and neurodevelopment) and contributes to neurodegeneration and cancer. We conclude with perspectives on future katanin research that will advance our understanding of this exciting and dynamic class of disease-associated enzymes.

Abstract
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. According to IR score (from 0 ~ 12), katanin P60/P80 expressions were classified as low (IR score 0 ~ 3) and high (IR score 4 ~ 12) expressions. Results Both katanin P60/P80 expressions were highly expressed in tumor tissue compared with adjacent tissue. Besides, tumor katanin P60 expression positively correlated with tumor katanin P80 expression. Tumor katanin P60 high expression correlated with larger tumor size, extrathyroidal invasion, advanced pT stage, pN stage, and pTNM stage, while no correlation of tumor katanin P60 expression with age or gender was observed; tumor katanin P80 high expression correlated with advanced pN stage and pTNM stage, whereas there was no correlation of tumor katanin P80 expression with age, gender, tumor size, extrathyroidal invasion, or pT stage. Furthermore, both tumor katanin P60/P80 high expressions correlated with shorter accumulating disease‐free survival. As for overall survival (OS), neither tumor katanin P60 nor P80 expression correlated with OS. Conclusion Katanin P60/P80 measurement might assist with tumor management and prognosis surveillance in PTC patients.

J Clin Lab Anal 2020; 34:e23141. [PMID: 31944409 PMCID: PMC7171325 DOI: 10.1002/jcla.23141] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/09/2019] [Revised: 10/22/2019] [Accepted: 11/15/2019] [Indexed: 12/21/2022] Open
Abstract
Objective The present study aimed to investigate the correlation of katanin P80 expression with clinicopathological features and survival profile in non–small‐cell lung cancer (NSCLC) patients. Methods Totally, 398 NSCLC patients treated by pulmonary resection were enrolled and their tumor specimens were collected to determine katanin P80 expression by immunohistochemistry (IHC) assay. Clinical data were collected at diagnosis, and survival data including disease‐free survival (DFS) and overall survival (OS) were assessed after treatment. Results There were 195 (49.0%) patients with katanin P80 high expression and 203 (51.0%) patients with katanin P80 low expression, respectively. Meanwhile, katanin P80 high expression was associated with larger tumor size (P = .001), lymph node (LYN) metastasis (P = .005), and advanced TNM stage (P = .001). As for survival data, katanin P80 high expression was correlated with reduced DFS (P < .001) and OS (P < .001). And forward stepwise multivariate Cox's regression revealed that katanin P80 high expression was an independent predictor for decreased DFS (P < .001) and OS (P < .001). Besides, further analysis indicated that DFS (P < .001) and OS (P < .001) were the shortest in patients with katanin P80 high+++ expression, followed by patients with katanin P80 high++ expression and then those with katanin P80 high + expression and katanin P80 low expression. Conclusion Katanin P80 correlates with larger tumor size, LYN metastasis, and advanced TNM stage, and serves as a potential biomarker for predicting poor survival in NSCLC patients.
