Abstract: SARS-CoV-2 pandemic has recently made the entire world come to a standstill. The number of cases in the world, especially India, have been increasing exponentially. The need of the hour is to assimilate as much data as possible to fast track the pipeline of bringing in new therapeutic tools against this fatal virus. In this brief communication, we aim to throw light on the various variants of the proteins involved heavily in the pathophysiology of COVID-19, namely Spike protein, ACE2, GRP78, TMPRSS2 and NSP-12. We also portray the molecular docking studies of these proteins with specific drugs that are currently being associated with the same. In our brief study, we come across a few key findings. First of all the combinations of the variants of spike protein and ACE2 binding show overall 25% unfavourable ΔΔG. Second, NSP12 is the most mutation prone among all the NSPs of the SARS-CoV-2 genome and the most common mutations are P323L and A97V. Third, we discovered the variants found in the Indian subpopulation that have greater binding with the currently investigated drugs.

Abstract: Dandy-Walker malformation (DWM) is characterized by complete or partial agenesis of the cerebellar vermis, cyatic dilatation of the forth ventricle, and enlarged posterior fossa. However, the mechanism is still not completely understood up to now. In this study, we reported a rare case that a foetus with DWM showed partial trisomy 12p and distal 15q deletion. Karyotype analysis and chromosomal microarray analysis (CMA) were not always concordant with each other, and it is suggested that they should be performed for prenatal genetic diagnosis together. DWM is a rare central nervous system malformation, reported in 1/25-30,000 live births, characterized by complete or partial agenesis of the cerebellar vermis, cyatic dilatation of the forth ventricle, and enlarged posterior fossa (Kumar et al. 2001; Klein et al. 2003; Agrawal et al. 2016). The neurological development of children with DWM may range from normal to severely retarded, and cause variable clinical feature. Although several efforts have been made to explore its pathogenesis, however, it is still not completely understood. During the past decade, some genetic loci, microdeletion or duplication have been reported to be associated with DWM, such as 9p trisomy, partial deletions of the long arm of chromosome 13, genes ZIC1 and ZIC4 (von Kaisenberg et al. 2000; McCormack et al. 2003; Grinberg et al. 2004). In the present study, we describe a prenatal diagnosis case that a foetus with DWM on ultrasound scanning accepted genetic testing, and it revealed a microduplication of 12p13.33p11.1 and microdeletion of 15q11.2 in 750K single nucleotide polymorphism (SNP) array, while it showed 46,XX,der(8)(8pter→8q24::12p10→12qter),i(12)(p10) in karyotyping.

Abstract: Low temperature (LT) causes significant yield losses in chickpea (Cicer arietinum L.). The sucrose starch metabolism is associated with abiotic-stress tolerance or sensitivity in plants. The changes in sugars and starch contents under LT in chickpea have already been studied, however, no information is available on LT-induced alterations in transcription of carbohydrate metabolic pathway genes in chickpea. To understand the differences in the regulation of sucrose and starch metabolism under LT, the expression of sucrose and starch metabolism genes was studied in leaves of cold-sensitive (GPF2) and cold-tolerant (ICC 16349) chickpea genotypes. The mRNA sequences of chickpea genes were retrieved from the public databases followed by confirmation of identity and characterization. All the genes were functional in chickpea. Between the two paralogues of cell wall invertase, cell wall invertase 3×2 (CWINx2) was the truncated version of cell wall invertase 3×1 (CWINx1) with the loss of 241 bases in the mRNA and 67 amino acids at N terminal of the protein. Comparison of expression of the genes between control (22°C day / 16°C night) and LT treated (4°C; 72 h) plants revealed that granule bound starch synthase 2 (GBSS2) and β-amylase 3 (BAM3) were upregulated in ICC 16349 whereas sucrose phosphate synthase 2 (SPS2), CWINx1, CWINx2 and β-amylase 1 (BAM1) were downregulated. In contrast to this, SPS2, CWINx1, CWINx2 and BAM1 were upregulated and GBSS2 downregulated in GPF2 under LT. The gene expression data suggested that UGPase, CWINs, GBSS2 and BAM3 are important components of cold-tolerance machinery of chickpea.
