G150 is an inhibitor of cyclic GMP-AMP synthase (cGAS; IC50 = 10.2 nM for the human enzyme).1 It is selective for human cGAS over mouse cGAS (IC50 = 25,000 nM). G150 inhibits dsDNA-induced expression of IFNB1 in THP-1 cells and isolated human monocyte-derived macrophages (IC50s = 1.96 and 0.62 ?M, respectively) but not LPS-induced expresssion of TNF or poly(I:C)-induced rRNA degradation in the same cells when used at a concentration of 10 ?M.

Vertical Transmission of Babesia microti in BALB/c Mice: Preliminary Report
PLoS One 2015 Sep 15;10(9):e0137731.PMID:26372043DOI:10.1371/journal.pone.0137731.
Babesia spp. (Apicomplexa, Piroplasmida) are obligate parasites of many species of mammals, causing a malaria-like infection- babesiosis. Three routes of Babesia infection have been recognized to date. The main route is by a tick bite, the second is via blood transfusion. The third, vertical route of infection is poorly recognized and understood. Our study focused on vertical transmission of B. microti in a well-established mouse model. We assessed the success of this route of infection in BALB/c mice with acute and chronic infections of B. microti. In experimental groups, females were mated on the 1st day of Babesia infection (Group G0); on the 28th day post infection (dpi) in the post- acute phase of the parasite infection (G28); and on the 90th and 150th dpi (G90 and G150 group, respectively), in the chronic phase of the parasite infection. Pups were obtained from 58% of females mated in the post-acute phase (G28) and from 33% of females in groups G90 and G150. Mice mated in the pre-acute phase of infection (G0) did not deliver pups. Congenital B. microti infections were detected by PCR amplification of Babesia 18S rDNA in almost all pups (96%) from the experimental groups G28, G90 and G150. Parasitaemia in the F1 generation was low and varied between 0.01-0.001%. Vertical transmission of B. microti was demonstrated for the first time in BALB/c mice.
Purification of human alpha uterine protein
J Reprod Fertil 1980 Mar;58(2):435-42.PMID:7431275DOI:10.1530/jrf.0.0580435.
Human alpha uterine protein (AUP) has been prepared from extracts of decudua by antibody affinity chromatography, DEAE Sepharose chromatography and by filtration through Sephadex G-150. This procedure yielded a protein fraction containing AUP, which was labelled with 125I by chloramine T. When analysed by SDS gel electrophoresis this radioiodinated protein fraction was found to contain predominantly a single species of protein which was precipitated by antibodies against AUP in antibody-antigen crossed electrophoresis. Rabbit anti-AUP precipitated 55-65% of the tracer in a double-antibody system. Sephadex G150 gel filtration of AUP obtained before and after affinity chromatography provided a molecular weight estimate of 50000. Since SDS gel electrophoresis revealed a polypeptide molecular weight of 23000-25000, it is suggested that AUP is a dimer.
The effect of 2 different single injections of high dose of vitamin D on improving the depression in depressed patients with vitamin D deficiency: a randomized clinical trial
J Clin Psychopharmacol 2013 Jun;33(3):378-85.PMID:23609390DOI:10.1097/JCP.0b013e31828f619a.
The correlation between vitamin D deficiency and depression has recently been put forward and resulted in controversial findings. The present study was conducted to find out the effect of 2 single injections of 150,000 and 300,000 IU of vitamin D on improving the depression in depressed patients with vitamin D deficiency.This clinical trial study was carried out during 2011-2012 in Yazd, Islamic Republic of Iran. A total of 120 patients who had a Beck Depression Inventory II score of 17+ and were affected with vitamin D deficiency were randomly assigned to 3 groups of 40. They included G300, G150, and NTG. G300 and G150 received an intramuscular single dose of 300,000 and 150,000 IU of vitamin D, respectively, and the NTG group received nothing. After 3 months of intervention, the depression state, serum vitamin D, calcium, phosphorus, and parathormone were measured.The median of serum vitamin D after intervention were 60.2, 54.6, and 28.2 nmol/L (P < 0.001) for the G300, G150, and NTG, respectively. Percentages of vitamin D deficiency after intervention were 18, 20, and 91.2 for the groups, respectively. The serum calcium mean showed a statistically significant increase in just the 2 test groups receiving vitamin D. There was only significant difference in mean of Beck Depression Inventory II test score between G300 and NTG (P = 0.003).The results of the study revealed that first, the correction of vitamin D deficiency improved the depression state, and second, a single injection dose of 300,000 IU of vitamin D was safe and more effective than a 150,000-IU dose.
Purification and subunit structure of glycogen-branching enzyme from rabbit skeletal muscle
Eur J Biochem 1980 Aug;109(2):391-4.PMID:6447599DOI:10.1111/j.1432-1033.1980.tb04806.x.
1,4-alpha-glucan:1,4-alpha-glucan 6-alpha-D-(1,4-alpha-D-glucano) transferase (branching enzyme) was purified by ammonium sulphate precipitation, chromatography on DEAE-cellulose, fractionation with poly(ethyleneglycol) 6000, chromatography on DEAE-Sepharose and gel filtration on Sephadex G150. The final specific activity was 3000 U/mg corresponding to a purification of approximately 10000-fold over the muscle extracts. 0.6 mg of enzyme was isolated from 4000 g muscle within eight days corresponding to an overall yield of 7%. The purified protein was homogeneous as judged by polyacrylamide gel electrophoresis in the presence of sodium dodecyl sulphate, and this technique yielded a molecular weight of 77000 for the subunit molecular weight of branching enzyme. The apparent molecular weight of the native enzyme determined by gel filtration on Sephadex G150 was 60000, demonstrating that branching enzyme is a monomeric protein. Only a very small proportion of the branching enzyme activity in muscle extracts (2%) precipitated with the protein-glycogen complex. This finding, and its low concentration in muscle, explain why a protein-staining band corresponding to branching enzyme cannot be detected by polyacrylamide gel electrophoresis of the protein-glycogen complex.
Detection of circulating hepatoma D23 antigen and immune complexes in tumour bearer serum
Br J Cancer 1973 Jul;28(1):16-24.PMID:4353387DOI:10.1038/bjc.1973.66.
Serum from rats bearing progressively growing aminoazo dye-induced rat hepatomata has been fractionated by Sephadex G150 gel filtration chromatography and isolated fractions have been examined by indirect membrane immunofluorescence techniques to detect tumour specific antigen and antibody. Hepatoma D23-specific antigenic activity was associated with material (of approximate molecular weight <150,000) isolated in the included volume of the gel at pH 7·3. The fraction excluded from the gel (of approximate molecular weight >150,000) was adjusted to pH 3·0 and further separated by Sephadex G150 gel filtration chromatography at pH 3·0 into gel included and excluded fractions. Hepatoma D23 specific antibody, demonstrable by membrane immunofluorescence staining of hepatoma D23 cells, was found to be eluted in the excluded volume and specific antigenic activity was retarded into the included volume of the gel. These results indicate that hepatoma D23 bearer serum contains free circulating tumour specific antigen in excess, together with specific immune complexes. The presence of these factors in tumour bearer serum is discussed in terms of "blocking" phenomena whereby serum factors may protect tumour cells from sensitized lymphocyte cytotoxic attack.
