[PMID: 36657523 DOI: 10.1016/j.clinre.2023.102086] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Revised: 09/05/2022] [Accepted: 01/15/2023] [Indexed: 01/18/2023]
Abstract
The Wnt/β-catenin signaling pathway is highly conservative. β-catenin is the key molecule in this pathway. The β-catenin target genes regulate cell proliferation and apoptosis. Since Wnt pathway proteins are distributed on the cell membrane, cytoplasm, and nucleus, inhibiting or activating these pathway proteins presents a novel target for cancer treatment via the Wnt signaling pathway. Studies have found that this pathway plays a significant role in the formation and progression of cancers, particularly colorectal cancer. We summarised the activation and inhibition of the Wnt signaling pathway in tumors, its relationship with the microenvironment and crosstalk with other pathways, and the effect of targeting abnormal Wnt signaling in the treatment of colorectal cancer. Here is to review future targeted therapeutics in colorectal cancer research and implementation.

Abstract
Heparan sulfate proteoglycans (HSPGs) are constituents of the cell surface and extracellular matrix and are vital for various activities within the cell. The N-deacetylase/N-sulfotransferase (heparin glucosaminyl) family of enzymes, or NDST, modifies heparan sulfate (HS) by catalyzing both the N-deacetylation and the N-sulfation of N-acetylglucosamine residues. In zebrafish, a single ndst3 gene is an orthologue of both mammalian NDST3 and NDST4 genes. The role of ndst3 in zebrafish development has not been investigated and such study may provide insight into the role(s) of both mammalian orthologues. Here, we characterized expression of ndst3 during early development in zebrafish and found it to be predominately neuronal. We found that expression of ndst3 is sensitive to Wnt signaling manipulation, with stimulation of the Wnt pathway resulting in robust expansion of ndst3 expression domains. Finally, using CRISPR/Cas9 genome editing, we mutagenized the ndst3 gene and isolated an allele, ndst3nu20, resulting in a frameshift and premature protein truncation. We discovered Ndst3 is not essential for zebrafish survival as ndst3nu20 homozygous mutants are viable and fertile.

Abstract
We study computational approaches for detecting SNP-SNP interactions that are characterized by a set of "two-locus, two-allele, two-phenotype and complete-penetrance" disease models. We argue that existing methods, which use data to determine a best-fitting disease model for each pair of SNPs prior to screening, may be too greedy. We present a less greedy strategy which, for each given pair of SNPs, limits the number of candidate disease models to a set of prototypes determined a priori.

Abstract
Regular exercise reduces depressive-like behavior activation. In this study, we look for exact roles of exercise on molecular and neuronal mechanisms for antidepressant action by studying the hippocampal neuroplasticity and proliferation. Increased hippocampal neurogenesis with exercise has potential significance for depression. Exercise promotes brain health in the molecular levels in the hippocampus and also affects behavior in a similar way to chronic antidepressant treatment. Wingless (Wnt) and frizzled signaling system plays an important role in cell proliferation, growth, and differentiation during development. Our results demonstrate complicated, differential effects of antidepressants on Wnt signaling system, and assume a role for selected signaling molecules in the neurogenic activity of antidepressant care. Our review suggests that exercise may preserve brain function by increasing neurogenesis through activating Wnt signaling pathway in the psychiatric disorders, such as depression.

Abstract
Lithium is the most commonly prescribed medication for the treatment of bipolar disorder (BD), yet the mechanisms underlying its beneficial effects are still unclear. We aimed to compare the effects of lithium treatment in lymphoblastoid cell lines (LCLs) from BD patients and controls. LCLs were generated from sixty-two BD patients (based on DSM-IV) and seventeen healthy controls matched for age, sex, and ethnicity. Patients were recruited from outpatient clinics from February 2012 to October 2014. LCLs were treated with 1mM lithium for 7 days followed by microarray gene expression assay and validation by real-time quantitative PCR. Baseline differences between groups, as well as differences between vehicle- and lithium-treated cells within each group were analyzed. The biological significance of differentially expressed genes was examined by pathway enrichment analysis. No significant differences in baseline gene expression (adjusted p-value < 0.05) were detected between groups. Lithium treatment of LCLs from controls did not lead to any significant differences. However, lithium altered the expression of 236 genes in LCLs from patients; those genes were enriched for signaling pathways related to apoptosis. Among those genes, the alterations in the expression of PIK3CG, SERP1 and UPP1 were validated by real-time PCR. A significant correlation was also found between circadian functioning and CEBPG and FGF2 expression levels. In summary, our results suggest that lithium treatment induces expression changes in genes associated with the apoptosis pathway in BD LCLs. The more pronounced effects of lithium in patients compared to controls suggest a disease-specific effect of this drug.

Abstract
Chronic organophosphorus pesticides (OP) exposure is associated with an increased risk of depression, and there is an urgent need to find an effective treatment for the depressive-like symptoms caused by OP. The main purpose of this study was to investigate whether combined lithium chloride (LiCl) and astaxanthin (AST) treatment would manifest synergetic antidepressant effects on mice with chronic OP exposure, and to determine the role of the Akt/GSK3β/CREB signaling pathway. Our results showed that chronic omethoate exposure significantly increased immobility time in behavioral tests and induced neuron damage in HE staining. The expression of p-GSK3β, p-CREB, p-PI3K and p-Akt in hippocampus after OP exposure were significantly down-regulated, while the influences were reversed by LiCl and AST treatment. Moreover, the combined application of AST and LiCl had synergistic therapeutic effects compared to LiCl and AST treatment alone, the expression of p-GSK3β, p-CREB, p-PI3K and p-Akt after combined LiCl-AST treatment were significantly higher than that with single drug application. These results showed that the combination of LiCl and AST could efficiently ameliorate depressive-like behavior induced by omethoate, and Akt/GSK3β/CREB signaling pathway might be responsible for the neuroprotective effect.

Abstract
Colorectal cancer is one of the most common gastric malignancies worldwide. However, the underlying mechanism of colon cancer development and valuable indicators of the disease remain unclear. In this study, the expression of frequently rearranged in advanced T-cell lymphomas 1 (FRAT1) in colon cancer was investigated and the association between FRAT1 expression and biological properties of tumors was analyzed. A total of 147 colon cancer tissue samples and adjacent normal tissues were collected between January 2013 and June 2014. The FRAT1 gene and protein expression levels were analyzed in tissues with different TNM and pathological stages. Small hairpin RNAs (shRNAs) containing the human FRAT1 gene were constructed and transfected into colon cancer HT-29 cells. The proliferation and migration of the cells was also analyzed in relation to a reduction in FRAT1 expression. In colon cancer tissues, the expression of FRAT1 was significantly higher when compared with adjacent tissues. In addition, FRAT1 expression was found to positively correlate with the degree of tumor malignancy, and this difference was determined to be statistically significant (P<0.05). Following shRNA transfection in HT-29 cells to decrease the expression of FRAT1, the proliferation and migration of the HT-29 cells decreased (due to conversion of the shRNA into small interfering RNA). These results indicate that in colon cancer, FRAT1 may present a novel tool for analyzing the tumor progression and may be a novel therapeutic target for the treatment of colon cancer.

Abstract
Despite significant research efforts aimed at understanding the neurobiological underpinnings of mood (depression, bipolar disorder) and psychotic disorders, the diagnosis and evaluation of treatment of these disorders are still based solely on relatively subjective assessment of symptoms as well as psychometric evaluations. Therefore, biological markers aimed at improving the current classification of psychotic and mood-related disorders, and that will enable patients to be stratified on a biological basis into more homogeneous clinically distinct subgroups, are urgently needed. The attainment of this goal can be facilitated by identifying biomarkers that accurately reflect pathophysiologic processes in these disorders. This review postulates that the field of psychotic and mood disorder research has advanced sufficiently to develop biochemical hypotheses of the etiopathology of the particular illness and to target the same for more effective disease modifying therapy. This implies that a "one-size fits all" paradigm in the treatment of psychotic and mood disorders is not a viable approach, but that a customized regime based on individual biological abnormalities would pave the way forward to more effective treatment. In reviewing the clinical and preclinical literature, this paper discusses the most highly regarded pathophysiologic processes in mood and psychotic disorders, thereby providing a scaffold for the selection of suitable biomarkers for future studies in this field, to develope biomarker panels, as well as to improve diagnosis and to customize treatment regimens for better therapeutic outcomes.

Abstract
The purpose of the present study was to evaluate the association between lithium levels in the public water supply and prefecture-based suicide rates in Greece. Analyses were conducted with respect to lithium levels in 149 samples from 34 prefectures of Greece. The average lithium level was 11.10 μg/l (range 0.1 to 121 μg/l). The results indicate that there is a tendency for lower suicide rates in the prefectures with high levels of lithium in drinking water. Ecological studies explained by researchers Schrauzer and Shrestha have revealed the existence of statistically significant inverse associations between the lithium levels in drinking water and the incidence of suicides, homicides, rapes, possession of narcotic drugs, and in juveniles, the rates of runaway from home. Such a result of inverse relationship was not proven by Kabacs et al., most likely because the differences of the lithium levels in the selection of their case-control samples were not large enough. In addition, probably the selection of random regions in Japan and East England might have been biased. Thus, the addition of small amounts of lithium to the drinking water could provide an effective means to lower the incidence of these conditions in the general population. Furthermore, the nutritional importance of lithium in the form of the carbonate named lithium carbonate (Li2CO3) is currently still viewed primarily as a pharmacological agent. The study by Al-Chalabi et al. state that the therapeutic activity of lithium in amyotrophic lateral sclerosis (ALS) is worth investigating. Any drug that can be shown to slow the course of ALS in a clinically significant way and to be safe and well tolerated will be an important advance for patients with this disease.

Abstract
OBJECTIVES To review the evidence of the involvement of the Wnt signalling pathway in mood disorders and in the action of drugs used to treat these disorders. METHODS We performed a careful PubMed search using as keywords all possible terms relevant to the Wnt pathway and crossing them with each of four areas, i.e., developmental effects, behavioural effects, mood disorders, and drugs used in their treatment. Papers were selected on the basis of their content and their data used for discussion. RESULTS Neurodevelopmental and behavioural data point to the possibility of involvement of the Wnt pathway in the pathophysiology of mood disorders. Clinical and post-mortem data are not sufficient to corroborate a definite role for Wnt alterations in any mood disorder. Combining genetic and pharmacological data, we may state that glycogen synthase kinase is the key molecule in bipolar disorder, as it is connected with many other signalling pathways that were shown to be involved in mood disorders, while Wnt molecules in the hippocampus appear to be mainly involved in depressive disorders. CONCLUSIONS Altered Wnt signalling may play a role in the pathophysiology of mood disorders, although not a central one. It is premature to draw conclusions regarding the possible usefulness of Wnt manipulations in the treatment of mood disorders.

Abstract
Mood disorders are marked by high rates of non-recovery, recurrence, and chronicity, which are insufficiently addressed by current therapies. Several patho-etiological models have been proposed that are not mutually exclusive and include but are not limited to the monoamine, inflammatory, neurotrophic, gliotrophic, excitatory, and oxidative stress systems. A derivative of these observations is that treatment(s) which target one or more of these mechanistic steps may be capable of mitigating, or preventing, disparate psychopathological features. Minocycline is an agent with pleiotropic properties that targets multiple proteins and cellular processes implicated in the patho-etiology of mood disorders. Moreover, preclinical and preliminary clinical evidence suggests that minocycline possesses antidepressant properties. Herein, we provide the rationale for conducting a randomized, controlled trial to test the antidepressant properties of minocycline.

Abstract
Aside from monoamine disturbances, recent evidence has implicated particular intracellular pathways, including Wnt signaling, in the pathogenesis of major depressive disorder. In the present study, we investigated the role of Wingless (Wnt)-Dishevelled (DVL)-glycogen synthase kinase 3β (GSK3β) signaling in the depression-like behaviors exhibited by rats exposed to chronic forced swim stress. We found that the rats subjected to forced swim stress for 14 consecutive days exhibited obvious depression-like behaviors and showed decreased levels of phosphorylated GSK3β and β-catenin in the hippocampus. Chronic citalopram treatment alleviated the depression-like behaviors and reversed the disruptions of the phosphorylated GSK3β and β-catenin in stressed rats. Furthermore, when the stressed rats with citalopram treatment received bilateral, dorsal hippocampus infusions of a DVL inhibitor, sulindac, the depression-like effects induced by chronic stress reappeared. These findings suggest that the Wnt-DVL-GSK3β signaling in the hippocampus is markedly involved in the pathophysiology of depression induced by chronic stress. The Wnt-DVL-GSK3β pathway may mediate the therapeutic action of citalopram, and the manipulation of DVL could be a target for novel antidepressants.

Increased serum Dickkopf-1 levels in drug-abusing psychotic patients. Prog Neuropsychopharmacol Biol Psychiatry 2012; 36:239-44. [PMID: 22122879 DOI: 10.1016/j.pnpbp.2011.11.006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2011] [Revised: 11/14/2011] [Accepted: 11/14/2011] [Indexed: 12/17/2022]
Abstract
BACKGROUND Dickkopf-1 (DKK1) is an inhibitor of the canonical Wnt pathway, which is known to be impaired in both psychotic and neurodegenerative disorders. Here, we examined serum DKK1 levels as an indicator of ongoing neurodegeneration in psychotic patients, with or without a recent or current history of drug abuse. METHODS We measured serum DKK1 levels by ELISA in 22 inpatients with psychosis and no history of drug abuse, 22 with psychosis and drug abuse, and 16 controls. We rated psychopathology using the following rating scales: the Positive and Negative Syndrome Scale (PANSS); the Clinical Global Impressions (CGI) severity scale; and the Global Assessment of Functioning (GAF) scale. Extrapyramidal motor symptoms were assessed by the Simpson-Angus Neurological Rating Scale (NRS). RESULTS Inpatients with psychosis and comorbid substance abuse showed significantly higher serum DKK1 levels than inpatients with psychosis and no comorbid substance abuse or controls. Comorbid patients had earlier onset, longer duration of psychosis, and more severe extrapyramidal motor symptoms. However, we did not find any significant correlation between DKK1 levels and rating scale scores. CONCLUSION Psychosis led to elevated serum DKK1 levels, and substance abuse led to a further increase. Knowing that there is a correlation between brain and blood levels of DKK1, we speculate that the observed increase in DKK1 levels reflects drug-induced neurotoxicity in our patients.

Abstract
Basic and clinical studies demonstrate that stress and depression are associated with atrophy and loss of neurons and glia, which contribute to the decreased size and function of limbic brain regions that control mood and depression, including the prefrontal cortex and hippocampus. Here, we review findings that suggest that opposing effects of stress and/or depression and antidepressants on neurotrophic factor expression and signaling partly explain these effects. We also discuss recent reports that suggest a possible role for glycogen synthase kinase 3 and upstream wingless (Wnt)-frizzled (Fz) signaling pathways in mood disorders. New studies also demonstrate that the rapid antidepressant actions of NMDA receptor antagonists are associated with activation of glutamate transmission and induction of synaptogenesis, providing novel targets for a new generation of fast-acting, more efficacious therapeutic agents.
