3Abe et al. [24], 2020https://pubmed.ncbi.nlm.nih.gov/32354168/miR-505-5p, miR-1255b-5p, miR-550b-2-5p, miR-4523, and miR-6795-3pmiRNAs downregulate WDR26, which is an apoptosis repressor factor.The study identified five miRNAs with fluctuating patterns correlated with the onset and course of cerebral infarction: miR-505-5p, miR-1255b-5p, miR-550b-2-5p, miR-4523, and miR-6795-3p. Higher levels of miR-376a-3p and downregulation of miR-3184-5p were associated with the onset of cerebral infarction.

6Zhu et al. [29], 2019https://www.webofscience.com/wos/woscc/full-record/WOS:000457370300001SCARNA10, TERC, LINC01481, FLJ23867, H3F3AP6, TNPO1P1LncRNA levels in the pathway of antigen processing and presentation were elevated at 24 h, while lncRNA levels in TRP channels and GABAergic synapses were downregulated on day 7 following stroke.SCARNA10, TERC, and LINC01481 showed significantly increased expression (P < 0.01), whereas FLJ23867, H3F3AP6, and TNPO1P1 showed significantly decreased expression (P < 0.05) in IS patient PBMCs compared to healthy controls.
7Cao et al. [31], 2020https://www.webofscience.com/wos/woscc/full-record/WOS:000513554900005LncMRTThe PI3K/Akt signaling pathway was recognized by IS as a key route due to dysregulated LncMRTs. Improved cell survival is linked to the serine/ threonine kinase PI3K, and this impact is partially mediated by the activation of the serine/threonine kinase Akt.The dysregulated LncMRT in IS (formed by PTEN, TFAP2A, and HOTAIR) suggests that PTEN is a key part of the PI3K/Akt signaling pathway by generating LncMRT.
8Wang et al. [33], 2022https://www.webofscience.com/wos/woscc/full-record/WOS:000711301400001LNC_000015, LNC_001727Because it encourages stem cell development and inhibits erythrocyte apoptosis, lncRNA is also thought to be useful in the treatment of ischemic disorders.Five differentially expressed lncRNAs (LNC_000015, LNC_001727, SNHG8, MIRLET7BHG, AF001548.5) were found in IS and were used to construct a pathway network that suggests their potential as biomarkers and therapeutic targets in IS linked with the inflammatory response.
9Zhang et al. [38], 2020https://www.webofscience.com/wos/woscc/full-record/WOS:000575004300053MCM3AP-AS1, LINC01089, ITPK1-AS1, HCG27These hub genes were connected to signaling pathways relevant to inflammation, according to functional analysis.Inflammatory associated DELs (MCM3AP-AS1/LINC01089/ hsa-miR-125a/FYN, ITPK1-AS1/ hsa-let-7i/RHOA/GRB2/STAT1, and HCG27/hsa-miR-19a/PXN) may function as a ceRNA network to accelerate the development of the genes.

11Li et al. [44], 2018https://www.webofscience.com/wos/woscc/full-record/WOS:000429737400001Cx37The dysregulation of eNOS production and activity is brought on by the Cx37 C1019T polymorphism, which causes the transfer of proline to serine and also influences endothelial function and elasticity, leading to atherosclerosis.The G allele of the Cx37 SNP rs1764390 was shown to be a risk factor for IS and the genotypes of the Cx37 SNP rs1764390 and rs1764391 are linked to an elevated risk of IS.

[45], 2020https://www.webofscience.com/wos/woscc/full-record/WOS:000601211900010RPS14, RPS15A, RPS24, FAU, RPL27, RPL31, RPL34, RPL35A, RSL24D1, EEF1B2The expression of sex-specific ribosomal differential genes during the early stages of stroke recovery may be the main underlying cause of sexually dimorphic diff in inflammatory responses.They showed that there are 10 upregulated genes with mostly ribosomal and protein synthesis- related functions (RPS14, RPS15A, RPS24, FAU, RPL27, RPL31, RPL34, RPL35A, RSL24D1, and EEF1B2).
13Shroff et al. [47], 2019https://www.webofscience.com/wos/woscc/full-record/WOS:000455396400002HDAC9 polymorphism rs2107595HDAC9 is a class IIa HDAC that is located at 7p21 and changes the chromatin state by removing acetyl groups from proteins.Both the rs2107595 risk allele-positive and risk allele-negative LVAS groups, as well as the risk allele-positive and risk allele-negative VRFC groups, did not significantly differ from each other.
14Williams et al. [48], 2017https://pubmed.ncbi.nlm.nih.gov/28495826/rs505922The production of thrombus during cerebrovascular injury is significantly influenced by vWF.Their results suggest that high vWF levels associate with the risk of stroke recurrence in both unadjusted (P = 0.0007, HR = 1.26) and fully adjusted (P = 0.018, HR=1.19) models, with the most strongly associated SNP-rs505922.
15Davis Armstrong et al. [49], 2021https://pubmed.ncbi.nlm.nih.gov/33661917/rs7025659, rs10757056, rs10118089, rs7020745, rs10125228, rs10757058, rs10118371Leukotriene B4 is a pro-inflammatory lipid mediator derived from arachidonic acid.Sphingosine and sphinganine were nominally related with five common variants and one different variant [rs10757056 (sphingosine only), rs10118089, rs7020745, rs10125228, rs10757058, and rs10118371]. The most significant association included leukotriene B4 and rs7025659- SPTLC1 (P = 6.12e-07; post-hoc comparison between TG to GG genotypes P = 3.00E-07).
16Davis Armstrong et al. [51], 2021https://pubmed.ncbi.nlm.nih.gov/34252155/cg03584380, which is located in an intron of ZDHHC6.The ZDHHC6 gene, which makes the palmitoyltransferase ZDHHC6, contains this methylation site in its first intron. ZDHHC6 is required for the palmitoylation of numerous significant ER proteins, including calnexin and the ITPR1.In the African population, cg03584380 [HR = 5.41 (2.91–10.06)] was significantly associated with the recurrence of stroke, but not in the European cohort.
17Soriano- Tárraga et al. [59], 2018https://pubmed.ncbi.nlm.nih.gov/29515201/DNAmDNAm affects the expression of genes and the structure of DNA, and fluctuates over the length of a human’s life.Biological aging, an epigenetic biomarker calculated from DNAm values, outperforms chronological aging in predicting mortality three months after an IS. This connection is particularly important in the etiology of LAA stroke.
18Miao et al. [64], 2021https://www.webofscience.com/wos/woscc/full-record/WOS:000685052900002Hypomethylation of the RIN3The RIN3 gene regulates the movement of the amyloid beta-protein and functions as an inducer to maintain the transit of GTP Rab5 to endosomes at the plasma membrane. This process interferes with the endocytosis of the amyloid protein, which is connected to cellular endocytosis.In the TIA/MIS group, the RIN3 gene’s overall methylation level was considerably lower than in the control group (diff = 0.02, P = 0.001), a result that was maintained in the cognitive impairment vs. non-cognitive impairment group (diff = −0.013, P = 0.01).

20Tufekci et al. [66], 2018https://www.webofscience.com/wos/woscc/full-record/WOS:000426733300001TRAIL mRNA expressionTRAIL is linked to five different receptors, two of which, DR4 and DR5 that cause apoptosis and inflammation.Serum TRAIL levels of stroke patients were statistically (P < 0.0001) lower at the time of admission than those of healthy controls.
Surprisingly, the follow-up study revealed that serum TRAIL levels considerably raised after the first month following stroke onset (P = 0.002).
In addition, the TRAIL mRNA expression in PBMC was substantially higher in the stroke patients than in the controls (P < 0.0001).
When compared to the first week after the onset of the stroke, TRAIL mRNA expression in PBMC was observed to be decreased (P < 0.001).
21Li et al. [68], 2021https://pubmed.ncbi.nlm.nih.gov/34188129/serum anti- AP3D1-antibody (s-AP3D1-Ab)AP3D1 was the target antigen that serum IgG antibodies identified in the plasma of individuals with atherosclerosis.s-AP3D1-Ab levels were substantially greater in AIS than in healthy donors. The levels of s-AP3D1-Ab were still considerably greater in patients with AIS than in healthy donors even after the subjects’ ages were matched to 65 years. The s-AP3D1-Ab-positive rates in healthy donors and patients with AIS and TIA were 2.4%, 10.1%, and 10.4%, respectively, at a cutoff value comparable to the average plus two SDs of the HD values.
