Particularly, genipin-BSA-CLEAs showed higher thermal and pH stability than CLEAs that were cross-linked using glutaraldehyde. Therefore, genipin represents an alternative to toxic compounds such as glutaraldehyde during cross-linking to prepare CLEAs.Antrodia cinnamomea is a precious Polyporaceous fungus with various bioactivities. This study reports the chemical identification and biological activities of sulfomalonoglucan, a sulfated polysaccharide (SPS), from the sodium sulfate enriched medium of the title fungus. The SPS-containing fraction was separated by gel filtration chromatography (GFC) to give the title SPS (denoted as Na10_SPS-F3). By analyzing the evidence for key inter-glycosidic linkages in the 1D and 2D NMR spectroscopic data, one possible repeat unit was proposed as Na10_SPS-F3 inhibited the secretion of tumor necrosis factor (TNF-α) and interleukin (IL)-6 after lipopolysaccharide (LPS) stimulation in RAW264.7 macrophages. Mechanistically, Na10_SPS-F3 downregulated TGFRII also attenuated the LPS-induced IκB-α degradation. Moreover, Na10_SPS-F3 inhibited lung cancer cell H1975 EGFR/ERK signaling. This is the first paper reporting a 3-O-sulfomalonyl glucan (Na10_SPS-F3) with eight 1,4-β-Glc moieties connected with ten 1,4-α-Glc moieties from Antrodia cinnamomea and its anti-inflammatory and anti-cancer activities.Considering the need of new lactic acid bacteria (LAB) for the production of novel biosurfactant (BS) molecules, the current study brings out a new insight on the exploration of cheese samples for BS producers and process optimization for industrial applications. In view of this, Lactobacillus plantarum 60FHE, Lactobacillus paracasei 75FHE, and Lactobacillus paracasei 77FHE were selected as the most operative strains. The biosurfactants (BSs) described as glycolipoproteins via Fourier-transform infrared spectroscopy (FTIR) exhibited antimicrobial activity against the food-borne pathogens. L. plantarum 60FHE BS showed an anticancer activity against colon carcinoma cells and had a week antiviral activity against Hepatitis A virus. Furthermore, glycolipoprotein production was enhanced by 1.42-fold through the development of an optimized process using central composite design (CCD). Emulsifying activities were stable after 60-min incubation from 4 to 120 °C, at pH 2-12, and after the addition of NaCl (2-14%). Characterization by nuclear magnetic resonance spectroscopy (1H NMR) revealed that BS produced from strain 60FHE was glycolipoprotein. L. plantarum produced mixed BSs determined by Liquid Chromatography/Mass Spectrometry (LC-MS). Thus, indicating that BS was applied as a microbial food prevention and biomedical. Also, L. plantarum 60FHE BS was achieved with the use of statistical optimization on inexpensive food wastes.L-asparaginase is an enzyme capable of hydrolyzing the asparagine to aspartic acid and ammonia. L-asparaginase is widely used in the treatment of acute lymphoblastic leukemia (ALL) and other cancers. Here, for the first time, the effects of a novel yeast L-asparaginase from Yarrowia lipolytica were studied on human lung (A549) and breast cancer (MCF7) cell lines as the solid cancer cell lines in terms of cell growth and metastasis inhibition. Functional analysis showed the L-asparagine deprivation mediated anti-proliferation effects by apoptosis induction and changes in the expression of target genes involved in apoptosis and migration pathways. The qRT-PCR analysis showed the higher expression levels of pro-apoptosis genes, including Bax, P53, caspase 3, caspase 8, and down-regulation of Bcl-2 anti-apoptotic gene in treated cells. On the other hand, there was no increase in ROS production in the treated cells. However, L-asparaginase treatment was able to significantly induce autophagy activation in A549 cells. Besides, wound healing assay showed that L-asparaginase could considerably inhibit the migration of A549 and MCF7 cells. Taken together, our results suggested that Yarrowia lipolytica L-asparaginase might be considered for enzyme therapy against breast and lung cancers.Corneal transplantation, by which the damaged cornea is replaced by a new one, suffers from limited access to HLA-compatible-donors and high maintenance and surgical costs. Therefore, artificial corneas are considered as alternative tools with promising prospects. In our previous study, a two-part-polymeric artificial cornea was composed of enhanced hydrophilic surface electrospun poly(ε-caprolactone) nanofibrous scaffold that is thermally connected to a polyvinyl alcohol-based hydrogel disk was prepared. Characterization tests revealed the prepared artificial cornea had similar biocompatible and structural characteristics regarding the natural cornea. In current study, human amniotic membrane extract containing growth factors, cytokines, anti-inflammatory factors, and anti-angiogenic factors was prepared, nano-encapsulated in chitosan-dextran nanoparticles, and physically decorated on the poly(ε-caprolactone)-polyvinyl-alcohol artificial cornea. Physicochemical and biological characterizations revealed the nano-decorated artificial cornea has more biocompatibility than the unmodified one. Our study demonstrated the bioactive macromolecules loaded on chitosan-dextran nanoparticles enhanced the anti-angiogenic property of artificial cornea through the sustained release of anti-angiogenic factors such as thrombospondin-1, endostatin, and heparin sulfate proteoglycan. Real-time-PCR and flow-cytometry assessments elucidated the vascularization was inhibited through a decrease in the expression of cluster of differentiation 31 and von-Willebrand-Factor. Our study proposed the use of biocompatible artificial cornea could be a promising strategy in corneal transplantation.The increasing use of sustainable manufacturing technologies in the industry presents a constant challenge for the development of suitable biocatalysts. Traditionally, improved biocatalysts are developed either using protein engineering (PE) or enzyme immobilization (EI). However, these approaches are usually not simultaneously applied. In this work, we designed and validated an enzyme improvement platform, Immobilized Biocatalyst Engineering (IBE), which simultaneously integrates PE and EI, with a unique combination of improvement through amino acid substitutions and attachment to a support material, allowing to select variants that would not be found through single or subsequent PE and EI improvement strategies. Our results show that there is a significant difference on the best performing variants identified through IBE, when compared to those that could be identified as soluble enzymes and then immobilized, especially when evaluating variants with low enzyme as soluble enzymes and high activity when immobilized. IBE allows evaluating thousands of variants in a short time through an integrated screening, and selection can be made with more information, resulting in the detection of highly stable and active heterogeneous biocatalysts. This novel approach can translate into a higher probability of finding suitable biocatalysts for highly demanding processes.Alginate and its derivatives are annually produced approximately 30,000 tons or more and are applied to various industries as they are natural polymers. The global market for alginate and its derivatives has been growing steadily. There is little research compared to other enzymes produced through biomass degradation or modification. An alginate lyase, MtAl138, from Microbulbifer thermotolerans DAU221 was cloned and identified in Escherichia coli BL21 (DE3). MtAl138 contains a highly conserved motif (R538TELR, Q607IH609, and YFKAGVY716NQ), which indicates that it belongs to the polysaccharide lyase family 7 (PL7). MtAl138, with a molecular weight of 77 kDa worked optimally at 45 °C and pH 7.4. MtAl138 showed twice as much activity as when there was no NaCl when there was between 100 and 600 mM NaCl. Moreover, its activity increased in organic solvents such as benzene, hexane, methanol, and toluene. Based on the thin layer chromatography analyses, MtAl38 is an endo-type enzyme that produces di-, tri-, or tetrasaccharides from polyG and polyM. This study provided that MtAl138 is an endoenzyme that showed outstanding enzymatic activity at concentrated salt solutions and organic solvents, which makes it a reasonably attractive enzyme for use in various industries.Uterovesical fistulas are the rarest of all urogenital fistulas, mostly occurring as a complication of cesarean section. We present a case of a 32-year-old woman, who noticed continuous vaginal urine leakage starting immediately after a vaginal delivery. The shortening of the uterine cervix was reported at 26th week of gestation, and a cervical pessary was placed. Shortly after delivery, the patient noticed the loss of urinary continence control, and she was diagnosed with urinary incontinence and hematuria. The office diagnostic hysteroscopy revealed uterovesical fistula. The correction procedure by transabdominal approach was performed by the team of gynecological and urological surgeons. Laduviglusib in vivo One year of follow-up, the patient reports no symptoms related to lower urinary tract dysfunction. Based on the literature search, we believe that his is the first study of a uterovesical fistula followed by the use of a cervical pessary for the prevention of preterm delivery. Our case is a clear reminder that symptoms of urinary incontinence after vaginal delivery should be carefully managed.In Yangtze River Delta white goat, hypermethylation of CMTM3 leads to a decreased expression level in high quality brush hair. However, the regulation of CMTM3 expression and its function in hair follicle stem cells (HFSCs) remains largely unknown. In this study, we investigated the regulation of CMTM3 expression, function, and molecular mechanism in HFSCs. The re-expression of CMTM3 significantly suppressed the proliferation of HFSCs by inducing G1 cell cycle arrest and promoting apoptosis. Moreover, the downregulation of CMTM3 promoted HFSC proliferation. Treatment with sh_CMTM3 and incubation in a DHT culture medium had the most significant growth-promoting effect. It was hypothesized that transcriptome analysis using RNA sequencing (RNA-seq) in samples would enable the identification of unique protein-coding and non-coding genes that may help uncover the role of CMTM3. Multiple genes and pathways were involved in this process, including 168 common DEGs, such as CXCL8 and E-selectin, which is reportedly involved in multiple regulatory pathways. These results indicated that CMTM3 can function as HFSCs through the induction of a G1 cell cycle arrest and promoted apoptosis by mediating crosstalk between several pathways and transcription factors. Our data is available in the National Center for Biotechnology Information (NCBI) database with the accession number PRJNA657430.
Diet-induced obesity (DIO) is associated with chronic, low-grade inflammation in the hypothalamus. The inflammatory pathway of the hypothalamus is activated during obesity, and inhibition of activation of the inflammatory pathway can partially reverse obesity. Therefore, exploring new targets for inhibiting hypothalamic inflammation will provide new ideas for the prevention and treatment of obesity. Liver kinase B1 (LKB1), a serine/threonine kinase, is a tumor suppressor and metabolic regulator. Recent studies have shown that LKB1 has a certain anti-inflammatory effect. However, a role of LKB1 in the regulation of hypothalamic inflammation remains unclear. Therefore, we examined whether LKB1 overexpression in the hypothalamus could weaken the hypothalamic inflammation and inhibit the development of obesity.

LKB1 overexpressing adeno-associated virus (AAV) particles were injected stereotactically into the third ventricle (3 V) of C57BL/6 mice fed with HFD. We assessed changes in body mass and adiposity, food intake, hypothalamic inflammatory markers, and energy and glucose metabolism.
