Abstract
Paraneoplastic neurological syndrome refers to certain malignant tumors that have affected the distant nervous system and caused corresponding dysfunction in the absence of tumor metastasis. Patients with this syndrome produce multiple antibodies, each targeting a different antigen and causing different symptoms and signs. The CV2/collapsin response mediator protein 5 (CRMP5) antibody is a major antibody of this type. It damages the nervous system, which often manifests as limbic encephalitis, chorea, ocular manifestation, cerebellar ataxia, myelopathy, and peripheral neuropathy. Detecting CV2/CRMP5 antibody is crucial for the clinical diagnosis of paraneoplastic neurological syndrome, and anti-tumor and immunological therapies can help to alleviate symptoms and improve prognosis. However, because of the low incidence of this disease, few reports and no reviews have been published about it so far. This article intends to review the research on CV2/CRMP5 antibody-associated paraneoplastic neurological syndrome and summarize its clinical features to help clinicians comprehensively understand the disease. Additionally, this review discusses the current challenges that this disease poses, and the application prospects of new detection and diagnostic techniques in the field of paraneoplastic neurological syndrome, including CV2/CRMP5-associated paraneoplastic neurological syndrome, in recent years.

Abstract
Colorectal cancer (CRC) is one of the most common malignancies worldwide. Collapsin response mediator protein 5 (CRMP5) belongs to a family of five cytosolic proteins that serve a major role in neural development. CRMP5 has been identified as a biomarker of numerous cancer types, including lung cancer and glioblastoma. However, the role of CRMP5 in CRC remains unclear. In the present study, CRMP5 was characterized as a novel biomarker of poor survival in CRC. CRMP5-overexpression in CRC cells promoted cell proliferation and migration while CPMP5-knockdown decreased cell growth and migration. A novel mechanism was uncovered, by which CRMP5 regulates MAPK signaling to drive CRC cell proliferation and development. Furthermore, CRMP5-overexpression induced chemotherapy resistance and tumor recurrence in CRC. Taken together, these results demonstrated the important role of CRMP5 in the development and proliferation of CRC cells and suggested that CRMP5 may be a novel therapeutic target for CRC.

Abstract
Microtubule-severing protein (MTSP) is critical for the survival of both mitotic and postmitotic cells. However, the study of MTSP during meiosis of mammalian oocytes has not been reported. We found that spastin, a member of the MTSP family, was highly expressed in oocytes and aggregated in spindle microtubules. After knocking down spastin by specific siRNA, the spindle microtubule density of meiotic oocytes decreased significantly. When the oocytes were cultured in vitro, the oocytes lacking spastin showed an obvious maturation disorder. Considering the microtubule-severing activity of spastin, we speculate that spastin on spindles may increase the number of microtubule broken ends by severing the microtubules, therefore playing a nucleating role, promoting spindle assembly and ensuring normal meiosis. In addition, we found the colocalization and interaction of collapsin response mediator protein 5 (CRMP5) and spastin in oocytes. CRMP5 can provide structural support and promote microtubule aggregation, creating transportation routes, and can interact with spastin in the microtubule activity of nerve cells (30). Knocking down CRMP5 may lead to spindle abnormalities and developmental disorders in oocytes. Overexpression of spastin may reverse the abnormal phenotype caused by the deletion of CRMP5. In summary, our data support a model in which the interaction between spastin and CRMP5 promotes the assembly of spindle microtubules in oocytes by controlling microtubule dynamics, therefore ensuring normal meiosis.

Abstract
Collapsin response mediator protein 5 (CRMP5), a member of the CRMP family, is expressed in the brain, particularly in the hippocampus, an area of the brain that can modulate stress responses. Social stress has a well-known detrimental effect on health and can lead to depression, but not all individuals are equally sensitive to stress. To date, researchers have not conclusively determined how social stress increases the susceptibility of the brain to depression. Here, we used the chronic social defeat stress (CSDS) model and observed higher hippocampal CRMP5 expression in stress-susceptible (SS) mice than in control and stress-resilient (RES) mice. A negative correlation was observed between the expression levels of CRMP5 and the social interaction (SI) ratio. Reduced hippocampal CRMP5 expression increased the SI ratio in SS mice, whereas CRMP5 overexpression was sufficient to induce social avoidance behaviors in control mice following exposure to subthreshold social stress induced by lentivirus-based overexpression and inducible tetracycline-on strategies to upregulate CRMP5. Interestingly, increased CRMP5 expression in SS and lenti-CRMP5-treated mice also caused serum corticosterone concentrations to increase. These findings improve our understanding of the potential mechanism by which CRMP5 triggers susceptibility to social stress, and they support the further development of therapeutic agents for the treatment of stress disorders in humans.

Abstract
CV2/CRMP5 is the most common antibody accompaniment of paraneoplastic choreoathetosis. We present a case of paraneoplastic choreothetosis with associated cerebellar dysfunction, peripheral neuropathy, and likely dysautonomia. Our patient developed a movement disorder after a cardiopulmonary arrest, which unfortunately masked the true etiology of his symptoms. He was later found to have extensive stage small cell lung cancer, with further evaluation revealing seropositivity for anti-CV2 antibodies. Choreoathetosis is a known sequelae of hypoxic-ischemic brain injury, but clinicians should continue to keep an open mind. The utility of immunotherapy is unclear in these circumstances and many physicians adopt a symptom-based approach.

Abstract
Paraneoplastic neurological syndromes (PNS) are immune-mediated complications of cancer associated with a broad spectrum of clinical manifestations. Optic neuropathy (ON) and myelitis are frequent manifestations of multiple sclerosis and neuromyelitis optic spectrum disorders but are considered as non-classical in PNS. Here, we report a case of PNS revealed by simultaneous bilateral ON and myelitis related to a cluster of three neural autoantibodies, in the setting of small cell lung cancer.

Abstract
Background Posterior reversible encephalopathy syndrome (PRES) is a rare neurological condition with many associated risk factors. The presentation varies and consists of seizures, impaired visual acuity or visual field deficits, disorders of consciousness, headaches, confusion and focal neurological deficits. The diagnosis relies on clinical presentation and MRI findings. Treatment and prognosis are related to the underlying etiology. Case presentation We present a 58-year-old woman with ovarian cancer who developed symptoms and radiologic signs of PRES with no apparent trigger other than a sudden increase in blood pressure for the first time in her life and before any treatment has begun. Antibodies to collapsin response-mediator protein-5 (CRMP-5), a malignancy related paraneoplastic protein, were identified in her CSF. Conclusions We present a novel and intriguing association between PRES and antibodies against CRMP-5 which may highlight a new etiology for this condition.

Abstract
We herein report a 76-year-old man who developed irritability and forgetfulness 5 months after the introduction of atezolizumab for the treatment of small cell lung cancer (SCLC). Brain magnetic resonance imaging showed lesions of the striatum, and an investigation of the serum revealed a high titer of anti-CRMP5 antibody. After stopping atezolizumab and starting steroid pulse therapy, these clinical features improved. Given these findings, it is considered that CRMP5-assciated striatal encephalitis was induced by atezolizumab in this case with SCLC.

Abstract
OBJECTIVES In men, human prostate cancer (PCa) has become the second most common cancer. miRNAs are short non-coding RNAs that can inhibit target gene mRNAs. Studies have showed that the alternation of miRNAs expression in cancer is relevant to pathogenesis of tumor. In present study, we aimed to investigate functions of miR-214-5p in PCa. MATERIALS AND METHODS 10 paired human prostate tumor tissues and homologous para-tumor tissues were recruited, and the levels of miR-214-5p and CRMP5 were respectively determined by qRT-PCR assay. Luciferase activity analysis was performed to explore the regulation of CRMP5 mRNA 3'UTR by miR-214-5p. Then, cell experiments, including cell proliferation, apoptosis, cell cycle, migration and colony formation ability, were performed after proper plasmids or RNAs transfection. RESULTS In PCa tissues and cell lines, expression of miR-214-5p was decreased compared with para-tumor tissues or normal prostate epithelial cell lines. Luciferase activity assay showed a direct combination of miR-214-5p and CRMP5 mRNA 3'UTR, and indicated that the absence of miR-214-5p in PCa cells may contributes to a high level of CRMP5. Cell experiments showed that miR-214-5p can induce inhibition of tumor cell growth, migration and colony forming efficiency, promotion of apoptosis and G1-phase arrest, on the other hand, co-expression of CRMP5 somewhat counteracted these phenotype induced by miR-214-5p. CONCLUSION Taken together, miR-214-5p shows tumor suppression effects in PCa cells. Loss expression of miR-214-5p in PCa increase levels of CRMP5 through regulating CRMP5 3'UTR, which could be a potential therapy target for PCa.

Abstract
AIMS AMPA receptor (AMPAR) and CRMP5 antibodies are relatively uncommon in limbic encephalitis, and patients with both antibodies are rare. We recently treated such a patient, but the patient died after active treatment. To further understand this disease, we conducted a case report and literature review. DISCUSSIONS To date, five encephalitis patients, including our patient, have been found to be positive for AMPAR and CRMP5 antibodies. The male-to-female ratio of the reported cases is 4:1, and the age range is 26 and 62 years old. All five patients presented with various neuropsychiatric symptoms, including insomnia, abnormal behavior, seizures, extrapyramidal symptoms, and autonomic dysfunction. Four patients had tumors (three invasive thymomas and one suspected lymphoma), and three cases died within a short period of time. No tumor was detected in one of the patients during the follow-up period; however, after active treatment, the outcome was poor, and the patient developed cachexia. One patient had good response to immunotherapy and tumor therapy and successfully returned to work. CONCLUSIONS The prognosis of encephalitis associated with AMPAR and CRMP5 antibodies is worse than that of the encephalitis associated with AMPAR antibodies alone. The most likely cause is that this encephalitis is more likely to be accompanied by malignant tumors, leading to a poor prognosis. In addition, it may also be due to some synergistic mechanisms between the two antibodies. Further studies aimed at the prognosis of this type of encephalitis are warranted.

Abstract
Paraneoplastic neurological syndromes (PNS) associated with anti-CV2/CRMP5 antibodies are rare in the literature. Various clinical manifestations can occur including paraneoplastic limbic encephalitis (PLE). Thymoma is one of the rare causes that can be associated with this syndrome. It has not been reported in the literature in children or adolescents to the best of our knowledge. We report a case of PLE in a 19-year-old male patient secondary to thymoma that was diagnosed after 5 years of onset. Anti-CV2/CRMP5 antibodies were positive in the serum and became negative after thymectomy. Diagnosis of PNS should be evoked in cases with atypical neurological manifestation and can be confirmed by the presence of onconeuronal antibodies. We report the first pediatric PLE secondary to thymoma associated with anti-CV2/CRMP5 antibodies.

However, the clinical course may be variable, and effective symptomatic management can precede the start of cancer treatment. CASE REPORT A 63-year-old man presented with insidious onset, slowly progressive generalized chorea for 1 year, later diagnosed as anti-CV2/CRMP5 autoantibody positive paraneoplastic chorea. His chorea was markedly improved with intravenous amantadine. DISCUSSION In patients with anti-CV2/CRMP5 autoantibody-related chorea, sequential follow-up of brain magnetic resonance imaging reveals progression from active inflammation to atrophy. Our report highlights the efficacy of intravenous amantadine in paraneoplastic chorea.

Abstract
Alzheimer's disease (AD) is a progressive neurodegenerative disease characterized by several behavioral disturbances, especially cognitive decline and deficits in social competence. Previous studies revealed that decreased social activity would accelerate AD progression, whereas enhanced social interaction could rescue AD-induced memory impairment. Collapsin response mediator protein 5 (CRMP5), which belongs to a family of cytosolic proteins, is abundantly expressed in the brain and is involved in the regulation of neurodevelopment and the pathology of several neuropsychiatric diseases. However, the functions of CRMP5 in AD are still unclear. Here, we demonstrated that 9-month-old 3xTg-AD mice exhibited social behavioral deficits and increased hippocampal CRMP5 levels compared to control (B6129S) mice. Knockdown of CRMP5 reversed the social deficits in 9-month-old 3xTg-AD mice, whereas CRMP5 overexpression decreased social interaction in both 3xTg-AD and control mice at 6 months of age. Interestingly, decreased expression of CRMP5 rescued AD-induced memory impairment, but overexpression of CRMP5 accelerated memory loss only in 3xTg-AD mice. In addition, we found that CRMP5 could regulate surface GluA2 and GluA2 S880 phosphorylation. These results suggest that CRMP5 regulates social behavior via modulation of surface GluA2 trafficking and affects memory performance in 3xTg-AD mice.

Abstract
Changing the microtubule dynamics is sufficient to alter the axon and dendrite specification and development. Spastin participates in the growth and regeneration of neurites by severing microtubules into small segments, and collapsin response mediator protein 5 (CRMP5) provides structural support and serves as a track for cargo transport by promoting microtubule polymerization. Nevertheless, how spastin and CRMP5 cooperate to regulate neurite outgrowth by controlling the microtubule dynamics needs to be elucidated. In our present study, spastin interacted with CRMP5 in vitro and in vivo. The binding domains for the spastin and CRMP5 interaction were the N-terminal fragment of spastin (residues 270-328) and the C-terminal fragment of CRMP5 (residues 472-564). Spastin and its truncation mutants, including the microtubule-binding domain (MTBD) and ATPases associated with diverse cellular activities (AAA) domain, were necessary for the severing of microtubules. Furthermore, we demonstrated that microtubule polymerization of CRMP5 interfered with the microtubule-severing function of spastin. Knocking down either spastin or CRMP5 inhibited neurite outgrowth in hippocampal neurons. However, co-transfected spastin and CRMP5 promoted the outgrowth of neurites including dendrites and axons. Taken together, our data support a model in which the spastin interaction with CRMP5 promotes neurite outgrowth by controlling the microtubule dynamics.

Abstract
Transcriptional regulation of proteins involved in neuronal polarity is a key process that underlies the ability of neurons to transfer information in the central nervous system. The Collapsin Response Mediator Protein (CRMP) family is best known for its role in neurite outgrowth regulation conducting to neuronal polarity and axonal guidance, including CRMP5 that drives dendrite differentiation. Although CRMP5 is able to control dendritic development, the regulation of its expression remains poorly understood. Here we identify a Sox5 consensus binding sequence in the putative promoter sequence upstream of the CRMP5 gene. By luciferase assays we show that Sox5 increases CRMP5 promoter activity, but not if the putative Sox5 binding site is mutated. We demonstrate that Sox5 can physically bind to the CRMP5 promoter DNA in gel mobility shift and chromatin immunoprecipitation assays. Using a combination of real-time RT-PCR and quantitative immunocytochemistry, we provide further evidence for a Sox5-dependent upregulation of CRMP5 transcription and protein expression in N1E115 cells: a commonly used cell line model for neuronal differentiation. Furthermore, we report that increasing Sox5 levels in this neuronal cell line inhibits neurite outgrowth. This inhibition requires CRMP5 because CRMP5 knockdown prevents the Sox5-dependent effect. We confirm the physiological relevance of the Sox5-CRMP5 pathway in the regulation of neurite outgrowth using mouse primary hippocampal neurons. These findings identify Sox5 as a critical modulator of neurite outgrowth through the selective activation of CRMP5 expression.

Abstract
Anti-α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor (AMPAR) encephalitis positive for additional onconeural antibodies is rarely reported. Here we report the clinical features of a patient who developed limbic encephalitis with both glutamate receptor 2 (GluR2) and collapsin response mediator protein 5 (CRMP5) antibodies. Brain magnetic resonance imaging revealed multifocal encephalopathy. Chest computed tomography showed a highly suspicious malignant thymoma. He experienced rapid neurological deterioration during hospitalization. This report indicates that the clinical diversity of anti-AMPAR encephalitis and the presence of onconeural antibodies may lead to poor prognosis.
