Abstract The proximate and mineral composition of the anatomical parts of adult male and female Sudananautes africanus africanus (common West African fresh water crab) were determined. The mineral composition of the ambient water was also determined. The lifeweights of the males varied between 92.18 and 140.36 g and the values ranged between 56.95 and 102.61 g in the females. The cheliped muscle recorded the highest value for protein and the lowest value for the total ash in both sexes, correlation coefficients (rMF) were positively related and high for protein (0.99), crude fat (0.84), total ash (0.99) and fibre (0.99) but negatively related in carbohydrate (-0.49) between the two sexes. The following minerals were highly concentrated in both sexes: Ca, Mg, Zn, Ni, P, Fe, Cu, Na and K with significant differences occurring in Ca, Mg, Zn, Ni, P, Fe, Cu and K at alpha < 0.05. Bioconcentration factors were found to be particularly high in the trace heavy metals: Co, Ni and Cu. All the various parts studied were found to be very good sources of the minerals examined with the exception of Co.

    Classically, the 3’untranslated region (3’UTR) is that region in eukaryotic protein-coding genes from the translation termination codon to the polyA signal. It is transcribed as an integral part of the mRNA encoded by the gene. However, there exists another kind of RNA, which consists of the 3’UTR alone, without all other elements in mRNA such as 5’UTR and coding region. The importance of independent 3’UTR RNA (referred as I3’UTR) was prompted by results of artificially introducing such RNA species into malignant mammalian cells. Since 1991, we found that the middle part of the 3’UTR of the human nuclear factor for interleukin-6 (NF-IL6) or C/EBP gene exerted tumor suppression effect in vivo. Our subsequent studies showed that transfection of C/EBP 3’UTR led to down-regulation of several genes favorable for malignancy and to up-regulation of some genes favorable for phenotypic reversion. Also, it was shown that the sequences near the termini of the C/EBP 3’UTR were important for its tumor suppression activity. Then, the C/EBP 3’UTR was found to directly inhibit the phosphorylation activity of protein kinase CPKC in SMMC-7721, a hepatocarcinoma cell line. Recently, an AU-rich region in the C/EBP 3’UTR was found also to be responsible for its tumor suppression. Recently we have also found evidence that the independent C/EBP 3’UTR RNA is actually exists in human tissues, such as fetal liver and heart, pregnant uterus, senescent fibroblasts etc. Through 1990’s to 2000’s, world scientists found several 3’UTR RNAs that functioned as artificial independent RNAs in cancer cells and resulted in tumor suppression. Interestingly, majority of genes for these RNAs have promoter-like structures in their 3’UTR regions, although the existence of their transcribed products as independent 3’UTR RNAs is still to be confirmed. Our studies indicate that the independent 3’UTR RNA is a novel non-coding RNA species whose function should be the regulation not of the expression of their original mRNA, but of some essential life activities of the cell as a whole.
