Abstract
This experiment investigated the sex responses of heat stress (HS) and subsequent recovery on growth performance, serum metabolic parameters, and redox status. Two hundred 38-day-old broilers were arranged in a completely randomized design with a 2 × 2 (temperatures and sexes) factorial arrangement in five replicates. Broilers were raised at 24 ± 1 °C or 32 ± 1 °C for 3 days and returned to 24 °C for 2 days. The study showed that HS decreased both average daily feed intake (ADFI), average daily gain (ADG), serum total glutathione peroxidase (GPx), and superoxide dismutase (T-SOD). However, it increased feed conversion ratio (FCR), rectal temperature (RT), respiratory rate (RR), serum glucose, blood urea nitrogen (BUN), low-density lipoprotein cholesterol, and the protein carbonyl group (PCG). Male broilers had higher ADFI, ADG, lactic acid (LA), high-density lipoprotein cholesterol (HDL-C), and PCG, but lower FCR, albumin, total antioxidant capacity, T-SOD, and GPx. Temperature and sex significantly interacted with ADFI, ADG, LA, and HDL-C. The effects of HS on RR, RT, glucose, albumin, BUN, PCG, T-SOD, and GPx recovered after 2 days. These results indicate that HS and subsequent recovery affect growth performance, which is accompanied by disturbances in serum nutrient metabolism and abnormalities in redox function and manifested by temporal and gender differences.

Abstract
BACKGROUND Pancreatic cancer is a complex disease with a desmoplastic stroma, extreme hypoxia, and inherent resistance to therapy. Understanding the signaling and adaptive response of such an aggressive cancer is key to making advances in therapeutic efficacy. Redox factor-1 (Ref-1), a redox signaling protein, regulates the conversion of several transcription factors (TFs), including HIF-1α, STAT3 and NFκB from an oxidized to reduced state leading to enhancement of their DNA binding. In our previously published work, knockdown of Ref-1 under normoxia resulted in altered gene expression patterns on pathways including EIF2, protein kinase A, and mTOR. In this study, single cell RNA sequencing (scRNA-seq) and proteomics were used to explore the effects of Ref-1 on metabolic pathways under hypoxia. METHODS scRNA-seq comparing pancreatic cancer cells expressing less than 20% of the Ref-1 protein was analyzed using left truncated mixture Gaussian model and validated using proteomics and qRT-PCR. The identified Ref-1's role in mitochondrial function was confirmed using mitochondrial function assays, qRT-PCR, western blotting and NADP assay. Further, the effect of Ref-1 redox function inhibition against pancreatic cancer metabolism was assayed using 3D co-culture in vitro and xenograft studies in vivo. RESULTS Distinct transcriptional variation in central metabolism, cell cycle, apoptosis, immune response, and genes downstream of a series of signaling pathways and transcriptional regulatory factors were identified in Ref-1 knockdown vs Scrambled control from the scRNA-seq data. Mitochondrial DEG subsets downregulated with Ref-1 knockdown were significantly reduced following Ref-1 redox inhibition and more dramatically in combination with Devimistat in vitro. Mitochondrial function assays demonstrated that Ref-1 knockdown and Ref-1 redox signaling inhibition decreased utilization of TCA cycle substrates and slowed the growth of pancreatic cancer co-culture spheroids. In Ref-1 knockdown cells, a higher flux rate of NADP + consuming reactions was observed suggesting the less availability of NADP + and a higher level of oxidative stress in these cells. In vivo xenograft studies demonstrated that tumor reduction was potent with Ref-1 redox inhibitor similar to Devimistat. CONCLUSION Ref-1 redox signaling inhibition conclusively alters cancer cell metabolism by causing TCA cycle dysfunction while also reducing the pancreatic tumor growth in vitro as well as in vivo.

Abstract
Inflammatory pain is a complex and multifactorial disorder. Apurinic/apyrimidinic endonuclease 1 (APE1), also called Redox Factor-1 (Ref-1), is constitutively expressed in the central nervous system and regulates various cellular functions including oxidative stress. In the present study, we investigated APE1 modulation and associated pain behavior changes in the complete Freund's adjuvant (CFA) model of inflammatory pain in rats. In addition we tested the anti-inflammatory effects of E3330, a selective inhibitor of APE1-redox activity, in CFA pain condition. We demonstrate that APE1 expression and subcellular distribution are significantly altered in rats at 4 days post CFA injection. We observed around 30% reduction in the overall APE1 mRNA and protein levels. Interestingly, our data point to an increased nuclear accumulation in the inflamed group as compared to the sham group. E3330 inhibitor injection in CFA rats normalized APE1 mRNA expression and changed its distribution toward cytosolic accumulation. Furthermore, intrathecal injection of E3330 decreased inflammation (i.e. reduced IL-6 expression) and alleviated pain, as assessed by measuring the paw withdrawal threshold with the von Frey test. In conclusion, our data indicate that changes in APE1 expression and sub-cellular distribution are implicated in inflammatory pain mechanisms mediated by APE1 redox functions. Further studies are required to elucidate the exact function of APE1 in inflammatory pain processes.

Abstract
The base excision repair (BER) pathway consists of sequential action of DNA glycosylase and apurinic/apyrimidinic (AP) endonuclease necessary to remove a damaged base and generate a single-strand break in duplex DNA. Human multifunctional AP endonuclease 1 (APE1, a.k.a. APEX1, HAP-1, or Ref-1) plays essential roles in BER by acting downstream of DNA glycosylases to incise a DNA duplex at AP sites and remove 3'-blocking sugar moieties at DNA strand breaks. Human 8-oxoguanine-DNA glycosylase (OGG1), methyl-CpG-binding domain 4 (MBD4, a.k.a. MED1), and alkyl-N-purine-DNA glycosylase (ANPG, a.k.a. Aag or MPG) excise a variety of damaged bases from DNA. Here we demonstrated that the redox-deficient truncated APE1 protein lacking the first N-terminal 61 amino acid residues (APE1-NΔ61) cannot stimulate DNA glycosylase activities of OGG1, MBD4, and ANPG on duplex DNA substrates. Electron microscopy imaging of APE1-DNA complexes revealed oligomerization of APE1 along the DNA duplex and APE1-mediated DNA bridging followed by DNA aggregation. APE1 polymerizes on both undamaged and damaged DNA in cooperative mode. Association of APE1 with undamaged DNA may enable scanning for damage; however, this event reduces effective concentration of the enzyme and subsequently decreases APE1-catalyzed cleavage rates on long DNA substrates. We propose that APE1 oligomers on DNA induce helix distortions thereby enhancing molecular recognition of DNA lesions by DNA glycosylases via a conformational proofreading/selection mechanism. Thus, APE1-mediated structural deformations of the DNA helix stabilize the enzyme-substrate complex and promote dissociation of human DNA glycosylases from the AP site with a subsequent increase in their turnover rate. SIGNIFICANCE STATEMENT The major human apurinic/apyrimidinic (AP) endonuclease, APE1, stimulates DNA glycosylases by increasing their turnover rate on duplex DNA substrates. At present, the mechanism of the stimulation remains unclear. We report that the redox domain of APE1 is necessary for the active mode of stimulation of DNA glycosylases. Electron microscopy revealed that full-length APE1 oligomerizes on DNA possibly via cooperative binding to DNA. Consequently, APE1 shows DNA length dependence with preferential repair of short DNA duplexes. We propose that APE1-catalyzed oligomerization along DNA induces helix distortions, which in turn enable conformational selection and stimulation of DNA glycosylases. This new biochemical property of APE1 sheds light on the mechanism of redox function and its role in DNA repair.
