Abstract
In order to evaluate the function of hypoxia-inducible factor-1 alpha (hif1α) and factor inhibiting hif1α (fih1) in response to thermal stress, we first conducted a functional analysis of A. sapidissima hif1α and fih1, and determined hif1α and fih1 expressions in different tissues in response to thermal stress based on identified housekeeping genes (HKGs). The results showed that hif1α and fih1 were mainly located in the nucleus and cytoplasm. The full length cDNA sequence of hif1α and fih1 was 4073 bp and 2759 bp, respectively. The cDNA sequence of hif1α includes 15 exons encoding 750 amino acid residues, and the full length cDNA sequence of fih1 contains 9 exons encoding 354 amino acid residues. During the acute thermal stress transferring from 16 ± 0.5 °C (control) to 20 ± 0.5 °C, 25 ± 0.5 °C, and 30 ± 0.5 °C for 15 min, it was found that the expression trends of hif1α and fih1 showed an inhibitory regulation in the heart, while they consistently expressed in brain, intestine, muscle, gill, kidney and liver. In conclusion, this is the first study to identify the tissue-specific HKGs in A. sapidissima and found that ef1α and β-actin are the most suitable HKGs. Hif1α and Fih1 are mainly the nuclear and cytoplasmic proteins, respectively, having high levels in the heart and brain. Alosa sapidissima countered a temperature increase from 16 to 25 ℃ by regulating the expressions of hif1α and fih1, but their physiological regulatory functions were unable to cope with acute thermal stress when the temperature difference was 14 ℃ (from 16 to 30 ℃).

Abstract
Duchenne muscular dystrophy (DMD) is a severe hereditary disease caused by a deficiency in the dystrophin protein. The most frequent types of disease-causing mutations in the DMD gene are frameshift deletions of one or more exons. Precision genome editing systems such as CRISPR-Cas9 have shown potential to restore open reading frames in numerous animal studies. Here, we applied an AAV-CRISPR double-cut strategy to correct a mutation in the DMD mouse model with exon 8-34 deletion, encompassing the N-terminal actin-binding domain. We report successful excision of the 100-kb genomic sequence, which includes exons 6 and 7, and partial improvement in cardiorespiratory function. While corrected mRNA was abundant in muscle tissues, only a low level of truncated dystrophin was produced, possibly because of protein instability. Furthermore, CRISPR-Cas9-mediated genome editing upregulated the Dp71f dystrophin isoform on the sarcolemma. Given the previously reported Dp71-associated muscle pathology, our results question the applicability of genome editing strategies for some DMD patients with N-terminal mutations. The safety and efficacy of CRISPR-Cas9 constructs require rigorous investigation in patient-specific animal models.

Therapeutic potential of highly functional codon-optimized microutrophin for muscle-specific expression. Sci Rep 2022; 12:848. [PMID: 35039573 PMCID: PMC8764061 DOI: 10.1038/s41598-022-04892-x] [Citation(s) in RCA: 10] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/20/2021] [Accepted: 01/03/2022] [Indexed: 12/26/2022] Open
Abstract
High expectations have been set on gene therapy with an AAV-delivered shortened version of dystrophin (µDys) for Duchenne muscular dystrophy (DMD), with several drug candidates currently undergoing clinical trials. Safety concerns with this therapeutic approach include the immune response to introduced dystrophin antigens observed in some DMD patients. Recent reports highlighted microutrophin (µUtrn) as a less immunogenic functional dystrophin substitute for gene therapy. In the current study, we created a human codon-optimized µUtrn which was subjected to side-by-side characterization with previously reported mouse and human µUtrn sequences after rAAV9 intramuscular injections in mdx mice. Long-term studies with systemic delivery of rAAV9-µUtrn demonstrated robust transgene expression in muscles, with localization to the sarcolemma, functional improvement of muscle performance, decreased creatine kinase levels, and lower immunogenicity as compared to µDys. An extensive toxicity study in wild-type rats did not reveal adverse changes associated with high-dose rAAV9 administration and human codon-optimized µUtrn overexpression. Furthermore, we verified that muscle-specific promoters MHCK7 and SPc5-12 drive a sufficient level of rAAV9-µUtrn expression to ameliorate the dystrophic phenotype in mdx mice. Our results provide ground for taking human codon-optimized µUtrn combined with muscle-specific promoters into clinical development as safe and efficient gene therapy for DMD.

Abstract
There is a lack of systematic research on the expression of internal control genes used for gene expression normalization in real-time reverse transcription polymerase chain reaction in spinal cord injury research. In this study, we used rat models of spinal cord hemisection to analyze the expression stability of 13 commonly applied reference genes: Actb, Ankrd27, CypA, Gapdh, Hprt1, Mrpl10, Pgk1, Rictor, Rn18s, Tbp, Ubc, Ubxn11, and Ywhaz. Our results show that the expression of Ankrd27, Ubc, and Tbp were stable after spinal cord injury, while Actb was the most unstable internal control gene. Ankrd27, Ubc, Tbp, and Actb were consequently used to investigate the effects of internal control genes with differing stabilities on the normalization of target gene expression. Target gene expression levels and changes over time were similar when Ankrd27, Ubc, and Tbp were used as internal controls but different when Actb was used as an internal control. We recommend that Ankrd27, Ubc, and Tbp are used as internal control genes for real-time reverse transcription polymerase chain reaction in spinal cord injury research. This study was approved by the Administration Committee of Experimental Animals, Jiangsu Province, China (approval No. 20180304-008) on March 4, 2018.

Abstract
Delivery of putative compounds of therapeutic value to the brain is limited by brain barriers: the blood–brain barrier located in the endothelium of the brain microvessels (BrMV) and the blood–cerebrospinal fluid barrier located in the epithelium of the choroid plexus (ChP). Understanding their function and modulation by the circadian clock may enhance the efficacy of brain-targeting therapies. The aim of the present study was to evaluate the stability of 10 reference genes in the BrMV and ChP, isolated from male and female rats at six time points (ZT1, 5, 9, 13, 17, and 21). Gene evaluations were performed by qPCR, analyzed by RefFinder tool, and verified by analyzing the expression of the brain and muscle ARNT-like 1 (Bmal1) using the qPCR and digital PCR methods. We identified as the most stable genes for circadian studies tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein zeta (Ywhaz) and apolipoprotein E (Apoe) for BrMV, and beta actin (Actb) and hypoxanthine-guanine phosphoribosyltransferase (Hprt1) for ChP. After verification, ribosomal protein (Rps18) was also included as a sufficient reference gene. Additionally, the observed gender difference in the Bmal1 oscillations in both BrMV and ChP suggests that separate studies for each gender are recommended.

Age and Sex-Dependent ADNP Regulation of Muscle Gene Expression Is Correlated with Motor Behavior: Possible Feedback Mechanism with PACAP. Int J Mol Sci 2020; 21:ijms21186715.

Abstract
The activity-dependent neuroprotective protein (ADNP), a double-edged sword, sex-dependently regulates multiple genes and was previously associated with the control of early muscle development and aging. Here we aimed to decipher the involvement of ADNP in versatile muscle gene expression patterns in correlation with motor function throughout life. Using quantitative RT-PCR we showed that Adnp+/− heterozygous deficiency in mice resulted in aberrant gastrocnemius (GC) muscle, tongue and bladder gene expression, which was corrected by the Adnp snippet, drug candidate, NAP (CP201). A significant sexual dichotomy was discovered, coupled to muscle and age-specific gene regulation. As such, Adnp was shown to regulate myosin light chain (Myl) in the gastrocnemius (GC) muscle, the language acquisition gene forkhead box protein P2 (Foxp2) in the tongue and the pituitary-adenylate cyclase activating polypeptide (PACAP) receptor PAC1 mRNA (Adcyap1r1) in the bladder, with PACAP linked to bladder function. A tight age regulation was observed, coupled to an extensive correlation to muscle function (gait analysis), placing ADNP as a muscle-regulating gene/protein.
