    Integrated overview of lignan biosynthesis and “Push-Pull-Release” strategies for plant lignan metabolic engineering. (A) Overview of the phenylpropanoid pathway leading to flavonoids, lignin, and lignan precursors. Sequential enzymatic conversions start from L-phenylalanine and branch into flavonoid biosynthesis and monolignol production for lignin monomer (H-, G-, and S-lignin). The principal enzymes and end products depicted are as follows: PAL, phenylalanine ammonia-lyase; C4H, cinnamate 4-hydroxylase; 4CL, 4-coumarate:CoA ligase; CHS, chalcone synthase; HCT, hydroxycinnamoyl-CoA:shikimate hydroxycinnamoyl transferase; C3’H, p -coumaroyl shikimate 3’-hydroxylase; CSE, caffeoyl shikimate esterase; C3H, coumarate 3-hydroxylase; COMT, caffeic acid <t>O-methyltransferase;</t> F5H, ferulate 5-hydroxylase; <t>CCoA-OMT,</t> <t>caffeoyl-CoA</t> O-methyltransferase; CCR, cinnamoyl-CoA reductase; CAD, cinnamyl alcohol dehydrogenase; LAC, laccase; PRX, peroxidase; H-lignin, hydroxyphenyl-lignin; G-lignin, guaiacyl lignin; S-lignin, syringyl-lignin. The pathway also highlights interconnections leading to lignan biosynthesis. Enzyme names are shown at each reaction step, and the main product classes are indicated at pathway termini. (B) Chemical structures of monolignol precursor (coniferyl alcohol) and representative lignans derived from phenylpropanoid pathway. (C) Biosynthetic pathway from coniferyl alcohol to sesamin and podophyllotoxin derivatives. This panel illustrates the enzymatic conversion steps starting from coniferyl alcohol as the precursor of lignan biosynthesis. Key enzymes and their full names are as follows: DIR, dirigent protein; PLR, pinoresinol-lariciresinol reductase; SDH, secoisolariciresinol dehydrogenase; CYP81Q1, (+)-piperitol/(+)-sesamin synthase; CYP719A23, (–)-pluviatolide synthase; OMT3, (–)-pluviatolide-O-methyltransferase; CYP71CU1, (–)-5’-desmethoxy-yatein hydroxylase; OMT1, (–)-5’-desmethyl-yatein O-methyltransferase; 2-ODD, 2-oxoglutarate/Fe(II)-dependent dioxygenase; CYP82D61, (–)-deoxypodophyllotoxin 4-hydroxylase; CYP71BE54, (–)-4’-desmethyl-deoxypodophyllotoxin hydroxylase. Each step highlights the enzyme responsible for the specific biochemical reaction ( <xref ref-type=Gasper et al., 2016 ; ; Yao et al., 2021 ). (D) Schematic representation of the “Push-Pull-Release” framework for lignan metabolic engineering. “Push” promotes precursor supply, “Pull” redirects flux by blocking competing pathways, and “Release” removes negative regulators to relieve pathway repression. These strategies are linked with synthetic biology tools for modular assembly, multiplex CRISPR, and spatiotemporal control to support lignan production and plant fitness (See Table 1 for a comparative overview of major engineering strategies and their risks and considerations).

The B-cell epitope regions predicted by the Kolaskar & Tongaonkar (KT) algorithm within IEDB are indicated by the dashed red lines and yellow highlight in protein structures. The KT antigenicity maps of endochitinase 1B and MetE are displayed in panels C and D, respectively. The residues in yellow regions indicate potential antigenic areas.

    m 5 C RNA methyltransferase NUSN2 is significantly upregulated in CC and its gene expression is associated with poor prognosis. (A) The level of m 5 C modification of RNA in CC cells was analyzed using a dot blot assay. Methylene blue staining served as an internal reference. (B) Semi-quantitative analysis of dot blot results in HeLa cells. (C) Semi-quantitative analysis of dot blot results in SiHa cells. (D) Expression levels of genes encoding m 5 C methyltransferases was analyzed within a CC database of TCGA. (E) HeLa and SiHa cells were incubated under hypoxia (0.1% O 2 ) and proteins collected at 24, 48 and 72 h were analyzed for NSUN2, TRDMT1 and GAPDH by western blotting. ImageJ was used to quantify western blotting signals from (F) HeLa and (G) SiHa cells. GAPDH served as an internal reference. (H) mRNA expression level of NSUN2 in 44 pairs of CC and paracancerous tissues were quantified using RT-qPCR. Gene expression in cancer tissues is expressed compared with expression in normal tissues. (I) Comparison of the average expression level of NSUN2 mRNA in CC tissues compared with paracancerous tissues. (J) Panoramic scans after IHC detection of NSUN2 and H&E staining in CC and paracancerous tissues. Scale bar, 50 µm. Magnification, ×20. (K) Protein levels of NSUN2 in 20 paired CC and paracancerous tissues, with the NSUN2 level in CC tissue expressed compared with that in the paired normal tissue. (L) Level of NSUN2 expression in CC was associated with a poor prognosis in the form of biochemical progression-free survival (P=0.018; log-rank test). *P<0.05, **P<0.01 and ***P<0.001.
