  • Davies KG,J Wolf-Phillips. Scientific Citizenship and good governance: implications for biotechnology. Trends in Biotechnology 2006, 24 (2): 57-61
    Yes. Science does not have boundary, and the scientists do have citizenships. But this scientific citizenship is different. It was proposed to "restore public trust and bridge the gap between science and the society that it serves".
  • Devlin RH, LF Sundstrom,WM Muir. Interface of biotechnology and ecology for environmental risk assessments of transgenic fish. Trends in Biotechnology 2006, 24 (2): 89-97
    Honestly, I still do not really get what the authors suggest in order to better use transgenic fish.
  • Nilsson M, F Dahl, C Larsson, M Gullberg,J Stenberg. Analyzing genes using closing and replicating circles. Trends in Biotechnology 2006, 24 (2): 83-88
    A review on analytical DNA circularization reactions, a good approach for high-throughout biological applications. Different models were discusssed in detail, including padlock probes and molecular inversion probes, selector-guided circularization of genomic sequences, circle-to-circle amplification, and Padlock probes in situ.
  • Palmer DH, LS Young,V Mautner. Cancer gene-therapy: clinical trials. Trends in Biotechnology 2006, 24 (2): 76-82

  • Evidence for an instructive mechanism of de novo methylation in cancer cells. Nature Genetics 38, 149 - 153 (2006) by Howard Cedar Group.
    we have adopted a new approach for detecting CpG island DNA methylation that can be used together with microarray technology. Genome-wide analysis by this technique demonstrated that tumor-specific methylated genes belong to distinct functional categories, have common sequence motifs in their promoters and are found in clusters on chromosomes.
    Their approach was to employ methyl-DNA immunoprecipitation (mDIP) assay, that used antibodies specific for 5-methyl–cytosine residues. They verified this approach by comparing tumor cell lines and normal cells. Then, they carried out genome-wide mDIP on DNA from the colon cancer cell line Caco-2. A set of 135 gene promoters that were specifically methylated in the cancer cell line
    The most interesting finding was the set of genes methylated differently in tumor cells. They also further verified the expression levels of those genes in colon cancer. This paper worthy of a further look.
  • MKS1, encoding a component of the flagellar apparatus basal body proteome, is mutated in Meckel syndrome. Nature Genetics 38, 141 - 143 (2006)
  • The transmembrane protein meckelin (MKS3) is mutated in Meckel-Gruber syndrome and the wpk rat. Nature Genetics 38, 191 - 196 (2006)
  • The role of microRNA-1 and microRNA-133 in skeletal muscle proliferation and differentiation. Nature Genetics 38, 228 - 233 (2005) by Da-zhi Wang at UNC.
    They showed miR-1 and miR-133 had distinct roles in modulating skeletal muscle proliferation and differentiation in cultured myoblasts in vitro and in Xenopus laevis embryos in vivo. Downsream pathways were also identified for those 2 miRNAs, including histone deacetylase 4 (HDAC4) and serum response factor (SRF) respectively.
  • Cooperative and antagonistic interactions between Sall4 and Tbx5 pattern the mouse limb and heart. Nature Genetics 38, 175 - 183 (2005) Published online: 25 December 2005; by Benoit G Bruneau group at The Hospital for Sick Children/U Toronto.
    TBX5, a gene encoding a T-box transcription factor, and SALL4, a gene encoding a zinc-finger transcription factor both are critical in limb formation. They found Tbx5 regulated Sall4 expression in the developing mouse forelimb and heart.
  • Physiogenomic resources for rat models of heart, lung and blood disorders. Nature Genetics 38, 234 - 239 (2006). By Norman H Lee at TREX Inst Genomic Res.
    The TIGR rodent expression web-based resource (TREX) contains over 2,200 microarray hybridizations, involving over 800 animals from 18 different rat strains.
    Interesting concept. It would become fairly useful for physiological research. Thanks to our progress in bioinformatics.

Data manipulation? or not.

Recently, prestigious NEJM expressed their concerns about two of those articles from Dr. Jon Sudbø at Radiumhospitalet in Oslo, Norway. Concerns have been forwarded to the director of that institution. An investigation was expected.

This, along with other incidents on Lancet and Science, has severely hurt the reputation of science! The integrity of science should always be kept as our highest priority, and no excuse would be granted to hurt it. While the indivisuals are blamed, I also believe there may be a system problem of our current scientific community. Do we chase for the data too urgently? Why can not we do science like 20 years ago, with the drive to discover Veritas rather than to publish?

It was a pity.

Stem cell genes linked to Male Germ Cell Tumors

Cancer Research reported:
12p Gene Cluster Projects Male GCT Stem-Cell Phenotype
Adult male germ cell tumors (GCT) show 12p gain in ~100% of cases, but the target genes are not clearly defined. In the January 15 issue of Cancer Research, Korkola et al. report results from _expression profiling that identified differentially expressed 12p genes within 101 GCT specimens. Genes in a 200kb cluster on 12p13.31, which included the stem-cell markers NANOG, GDF3, and STELLAR, were over-expressed in embryonal carcinoma and seminoma specimens but not in other GCT subtypes. To learn more, click here.

So are those the genes invovled in the development of cancer stem cells, at least in male germ tumors? It would also be interesting to look into the role of those new discovered stem cell-related genes in regulation of stem cell behaviors.

Letter to scienceblogs

Dear staff,

My blogs are http://zhanglab.blogspot.com/ and http://drslk.blogspot.com

The Zhang Lab was dedicated into stem cell research, also covering recent biomedical literatures of general interest, for stem cell biologists. It includes highlights in stem cell research (HiSCR), journal club and general readings (GR). HiSCR was a collection of recent publications with immediate interest to stem cell biologists. I generally browse and pick up papers from Impact Factor more than 10 or so, therefore, the data in the paper would be more solid or less likely a fraud. In weekly journal club, I would discuss significance, perspective and problems/arguments about 1 or 2 recent interesting papers. Hopefully, JC would stimulate more serious thinking about such subject. GR is for brain storm, in my view. This collective reading list may help broarden our science thinking in certain way. These 3 parts would fit into general biologist or experienced stem cell biologist, as I propose
The later Dr. SLK was for clinical medicine with focus on pathology, which would become my clinical training specialty. I would comment on recent progress in medical fields, including general health news and publication in medical journals such as JAMA, NEJM, BMJ, Lancet, etc.

I have tried to find a place/site where many good scientists share their blogs of serious scientific thinking. With a link from Nat Genetics Blog, I found you site, and thought it would fit my blog perfectly.

Thank you very much for your consideration.

Science
--Retraction of Hwang et al., Science 308 (5729) 1777-1783. Retraction of Hwang et al., Science 303 (5664) 1669-1674. Science 311, 335Interestingly, the first 2004 paper still has 7 authors refused to admit frauds. Maybe, the dog was real.
--Chromosomes Can Congress to the Metaphase Plate Before Biorientation
See Science 20 January 2006, 311, 388 - 391 and commentary. New wine in old bottle. Mitosis was further elucidated with the combination of live imaging system, molecular biology and chemical biology. Not my expertise, so no further comments.
--Sampling the Antibiotic Resistome Science 20 January 2006: 311, 374 - 377 A new some-ome. With the completion of Human Genome Project, Wright GD established a new one, namely antibiotic resistome. This paper gave us an early warning of antibioltic resistance. Out of 480 sampled microbes, very one of them was found resistant to 6-8 different antibiotics and some to as many as 20. See also perspective.

Nature
--New publishing rule on Cloning Nature 439, 243 (19 January 2006)
1.Mitochondrial DNA fingerprint comparison should be submitted to Nature, in addition to nuclear DNA FP.
2.If new ESC was established, one must compare its nuclear DNA fingerprint with existing ESC lines.
3.No independent verification is required, but be ready! Maybe Nature will ask for it in RARE cases.
4.To deposit to ATCC? Nature is weighing this reqirement.
--Sea of change. Nature 439, 256-260 (19 January 2006)
--Blue faculty Nature 439, 254 (19 January 2006).
AAMC new study suggests faculty members in med schools of US have as many as 1 of 5 depression symptoms. Young members and physicians have more chances.
--Scientific publishing: Peer review, unmasked. Nature 416, 258-260 (21 March 2002)
Open access peer review? Some new journals are experimenting this new way of paper evaluation. Given the competitiveness of biomedical fields, no big journals plan to adapt this open access peer review system.
--Cancer biology: Signatures guide drug choice. Nature 439, 274-275 (19 January 2006)
---Oncogenic pathway signatures in human cancers as a guide to targeted therapies. Nature 439, 353-357 (19 January 2006)
Joseph R. Nevins group at Duke showed deregulated oncogenic pathways differed in tumor types and correlated with clinical outcomes.
--- BRAF mutation predicts sensitivity to MEK inhibition Nature 439, 358-362 (19 January 2006) by Neal Rosen group at MSKCC.
They compared the sensitivities to ERK inhibitors in cancer cell lines with mutations of BRAF and RAS, both in vitro and in vivo. Addiontal mechanism was edemonstrated including loss of D-cylcin expression, Rb physphorylation, and G1 arrest induced by ERK inhibitor.

My 3 blogs

It will be good to have one's own lab, but if not, one still can run for preparing for it. The Zhang Lab blog is my way of doing so. Now I'm serious about.

The main purposes of this site were
1, Pick recent papers of my special interest, if not significance;
2, Record my own experience about maturing to become an independent investigator;
3, Collect papers, and articles about sciencetific community.

Also, I am running this Dr SLK site, that was meant for my node site. Now it's been switched to the site of interesting health news. I plan to comment on those news a little bit, if possible.

The last one is my Chinese sina blog, that was meant for translation work on NEJM, and other leading medical journals. After running it for a while, I found I was not able to catch up with all 4-5 journals, including NEJM, JAMA, BMJ, Lancet, AIM, etc. It was of no choices but stopping translating all of those journals. Though I should and plan to continue reading them periodicaly.

About me, Lanjing Zhang

I am interested in stem cell biology, focusing on normal and cancerous pancreatic stem cells. I dream to have my own lab some day, hopefully, amongst those top stem cell and/or pancreatic cancer labs.

Currently, I am pursuing residency training in anatomic and clinical pathology at Mount Sinai Medical Center, New York City, that would provide me wonderful opportunities to explore the cellular and molecular mechanism of diabetes and pancreatic cancer. It is also one of the main reasons why I picked up Pathology as my medical specialty. And the other is my love of diagnosing diseases through slides.

Here is my profile on COS.

Nature Jobs-1 Meetings

Just came cross a very impressive website about a career in science, nature jobs. Actually, more than just a career in science. Many pieces of advice were given regarding how to start your own lab, how to meet up peers in a meeting, etc. Well organized.
It's nature jobs

First article of my interest is the one about how to meet up with peers in a meeting. It is always rough to join the meeting, like a lost chicken as one of them said. The article is Nature 438, 1187 (December 2005) | doi:10.1038/nj7071-1187a , including two out linked articles Small conferences pay their way Nature 438, 264-265 (17 November 2005) and Meeting up Nature 436, 1060-1061 (August 2005). The Editor Paul Smaglik argues meetings would provide new collaborations and insights.
